Follow all applicable guidelines for siting the components before continuing with
these installation instructions.

There may be some variation in the process depending on the type and number of
drive components in your particular installation.

Connect Shipping Splits ATTENTION: Install the drive on a level surface (+/- 1 mm per meter
[+/- 0.036 in. per 36 in.] of drive length in all directions). If necessary, use
metal shims to level the cabinets before joining them; attempting to level after
joining may twist or misalign the cabinets.

Connect DV/DT Filter Cabinet for A-Frame Drives

The standard A-Frame for PowerFlex 6000 drives comes fully assembled and does
not require any shipping splits. However, if a DV/DT filter is included with the
drive then there is one shipping split, and the drive and filter must be connected
as follows:

1. Remove the M16x16 countersunk screw that secures the LV covers and
grounding cover at the right side of the main drive, and the left side of the
filer cabinet. Then remove the covers.
2. Arrange the sections as described in the Dimensional Drawings and move
the sections together.

4. Remove all back plates to access rear edge joining holes (five places).

TIP Each back plate will have two keyhole screw holes on either side. Remove all
other screws first. Loosen the two screws in the keyhole screw holes last and
lift the back plate to remove. Do not remove these screws.
Do not replace the back plates until the Drive Electrical Interconnection Process
is complete (See Drive Electrical Interconnection on page 57).
To replace the back plates, the two remaining screws orient and hold the back
plate in place while fastening the other screws holding the back plates to the
frame of the cabinet. Tighten these screws last to complete the process.

Chapter 1 Drive Mechanical Installation

External Ducting The PowerFlex 6000 design can accommodate ducting exhaust air outside of the
control room.

ATTENTION: The Isolation Transformer Cabinet and the Power Module/LV

Control Cabinet must be ducted separately.

The following requirements are mandatory design requirements for systems that
will externally duct the exhaust air and draw cleansed outside air:

• External ducting including an external filtering system must not add more
than 50 Pa (0.2 in. of water) pressure drop to the PowerFlex 6000 drive
airflow system. Ensure a minimum top clearance of 1500 mm (39.4 in.)
above the drive top plate.

• The control room must provide slightly more make-up air, creating a
pressurized room. This slight pressurization prevents unfiltered air
drawing into the room.

• The drive is intended to operate in conditions with no special precautions

to minimize the presence of sand or dust, but not in close proximity to
sand or dust sources. IEC 721-1 defines this as being less than 0.2 mg/m3
of dust.

• If outside air does not meet this condition, filter the air to EU EN779
Class F6 or ASHRAE Standard 52.2 MERV 11. These ratings address a
high percentage of the 1.0...3.0 μm particle size. Clean or change filters
regularly to ensure proper flow.

• The make-up air must be between 0...40 °C (32...104°F).

• Relative humidity must be less than 95% noncondensing.

• If the ducting length is greater than 4 m (13 ft), an axial fan must be
installed at the air outlet. The exhaust flow of the axial fan must be greater
than the total flow amount of all centrifugal fans in this air duct.

• The ducting can be shared by more than one cabinet.

• Do not cover any medium voltage or control power wires that enter or exit
from the top of the cabinet.

• The air duct outlet must slope downward to prevent water damage.

• Screens must be installed in the air duct outlet.

• An air inlet must be added to the drive room. The cross-sectional area of
this inlet must meet the ventilation requirements of all drives. Screens
must be installed in the air inlet.
• The air inlet and outlet must not be at the same side of the drive room.

Drive Electrical Installation

Introduction The installation of all external power cables and control signal wiring is covered
in this chapter. General electrical safety and installation guideline topics are also
included. The basic activities include connecting the system ground cable, line
and motor cables, control power, and all control signal wiring from the sources to
the drive. See Figure 45 and Figure 46 for an overview of these connections.

Electrical interconnections are also required between cabinets that have shipped
separately. These are described in Drive Electrical Interconnection on page 57.

Safety and Codes SHOCK HAZARD: Connecting to potentially energized industrial control
equipment can be dangerous. Severe injury or death can result from electrical
shock, burn, or unintended actuation of control equipment. Hazardous voltages
may exist in the cabinet even with the circuit breaker in the off position.
Required practice is to disconnect and lock out control equipment from power
sources, and confirm discharge of stored energy in capacitors. If it is necessary
to work in the vicinity of energized equipment, the safety-related work
practices that are outlined in Electrical Safety requirements for Employee Work
places must be followed. Before attempting any work, verify that the system
has been locked out and tested to have no potential.

Lockout and tagout the input circuit breaker before performing any electrical
connection work. After the input circuit breaker cabinet doors are opened,
immediately test the outgoing connections and any components that are
connected to medium voltage with a live-line tool (hot stick) while wearing high-
voltage gloves. Pay special attention to any capacitors connected to medium
voltage that can retain a charge for a period of time. Only after the equipment has
been verified as isolated and de-energized can subsequent work be performed.
Even though the input to the drive may be open, it is still possible for hazardous
voltage to be present.
See national and local safety guidelines for detailed procedures on how to safely
isolate the equipment from hazards.

ATTENTION: The national and local electrical codes outline provisions for safely
installing electrical equipment. Installation must comply with specifications
regarding wire type, conductor sizes, branch circuit protection, and disconnect
devices. Failure to do so may result in personal injury and/or equipment
damage.

Rockwell Automation Publication 6000-IN006H-EN-P - October 2020 39

Chapter 2 Drive Electrical Installation

Electrical Drawings Before connecting any power cables or control signal wiring, review and
understand the information that is contained in the project-specific Electrical
Drawings.

They contain critical information such as:

• Minimum power cable insulation ratings and sizes
• Power terminal locations and designations
• Terminal block designations for all connections to external customer
control signal wiring and control power supply cables.

The practice that is used within the PowerFlex 6000 electrical drawing is based
on the IEC or NEMA standard depending on the requirements. The symbols
used to identify components on the drawings are international.

Device designations that are used on the drawings and labeling are explained on
each drawing set.

Wiring identification uses a source/destination wire number convention on

point-to-point multi-conductor wiring and in situations where the system is
warranted. The wire-numbering system of unique, single numbers for multi-drop
and point-to-point wiring continues to be used for general control and power
wiring.

Wiring that connects between the sheets or that ends at one point and starts at
another point on a drawing has an arrow and drawing reference to indicate the
ongoing connection. The drawing reference indicates the sheet and the X/Y
coordinates of the continuation point. The reference system is explained on a
sheet in each drawing set. The unique wire numbering system serves as
confirmation that the correct wire is being traced from sheet-to-sheet or across a
drawing. Wires in multi-conductor cables are typically identified by color rather
than by number. Abbreviations used to identify the colors on the drawings are
fully identified on a sheet in the drawing set.

Grounding System As a general guideline, the ground path must be of sufficiently low impedance
and capacity that:
Requirements
• the rise in potential of the drive ground point when subjected to a current
of twice the rating of the supply should be no higher than 4V over ground
potential
• the current flowing into a ground fault is of sufficient magnitude to cause
the protection to operate.

The general grounding point must be reliably connected with the grounding
network.

40 Rockwell Automation Publication 6000-IN006H-EN-P - October 2020

 Drive Electrical Installation Chapter 2

Attach an external ground cable to the main ground bus, in compliance with
applicable national and local electrical codes.

IMPORTANT The primary grounding cable must have a diameter of at least 50 mm2 and
meet all applicable national and local electrical codes.

Run the system ground cable separately from power and signal wiring so that
faults:
• do not damage the grounding circuit
• will not interfere with or damage the protection or metering systems, or
cause undue disturbance on power lines.

Power Cable Insulation Incoming line power cable ratings are shown on the Electrical Drawings and
reflect what would typically be supplied, based on line voltage rating.
Requirements
All voltage ratings for outgoing motor cables that are shown are line-to-ground
rated power-frequency voltages and line-to-line power-frequency voltages.
Table 5 - Cable Insulation Requirements for Outgoing Motor Cables

6900 ≥4.8 ≥8.3
10,000 ≥6.4 ≥11.1
11,000 ≥7.2 ≥12.5

Select cables of appropriate voltage classes when the incoming line grid-side
voltage class differs from the outgoing line motor-side voltage class.

Standard power cable ratings commercially available can vary in different regions
around the world. Cable must meet the minimum line-to-ground and line-to-
line requirements.

IMPORTANT Follow the recommended field power cabling insulation levels to help ensure
trouble-free startup and operation. The cable insulation level must be
increased over that which would be supplied for an across-the-line application
with the same rated line-to-line voltage.

Rockwell Automation Publication 6000-IN006H-EN-P - October 2020 41

Chapter 2 Drive Electrical Installation

Power Cable Design Use fire retardant cables for the drive input/output connections.
Considerations Shielded or unshielded cable can be used based on the criteria that are considered
by the distribution system designer and national and local electrical codes.

If shielded power cables are used, connect the shield of the main input/output
power cables with the general grounding point of the drive. Ground the drive
output protective grounding connection separately, and only at the drive side.

Comply with the maximum tensile stress and the minimum curvature radius that
is recommended by the cable manufacturer.

Do not bundle the input/output cables of the drive together.

The power cable tray must not be less than 300 mm (12 in.).

There must be no gaps where the conduit connects to the cabinet and the ground
bond must be less than 0.1 ohms. Spacing between wire groups is the
recommended minimum for parallel runs of approximately 61 m (200 ft) or less.

IMPORTANT PowerFlex 6000 drives are able to operate motors if the cable length is less
than 800 m (2624 ft). Contact the factory when cable lengths at the drive
output exceed 800 m (2624 ft).
When the cable length is longer than 800 m (2624 ft), an assessment is
required. It does not necessarily mean that an output filter is required.
Configurations can be provided for longer cable distances, but must be
specified at the time of order.

All input and output power wiring, control wiring, or conduit must be brought
through the conduit entrance holes of the cabinet. Use appropriate connectors to
maintain the environmental rating of the cabinet.

Motor Cable Sizing Voltage drop in motor leads may adversely affect motor starting and running
performance. Installation and application requirements may dictate that larger
wire sizes than indicated in national and local electrical codes are used.

Wire sizes must be selected individually, observing all applicable safety and
national and local electrical codes. The minimum permissible wire size does not
necessarily result in the best operating economy. The minimum recommended
size for the wires between the drive and the motor is the same as that used if a
main voltage source connection to the motor was used. The distance between the
drive and motor can affect the size of the conductors used.

Consult the Electrical Drawings and appropriate national and local electrical
codes to determine correct power wiring. If assistance is needed, contact your
local Rockwell Automation Sales Office.

42 Rockwell Automation Publication 6000-IN006H-EN-P - October 2020

 Drive Electrical Installation Chapter 2

Control Signal Wiring Design Use shielded cables for all analog and digital control cables.
Considerations Steel conduit or a cable tray can be used for all PowerFlex 6000 drive power or
control wiring; however, use only steel conduit for all signal wiring.

ATTENTION: Steel conduit is required for all control and signal circuits when
the drive is installed in European Union countries.

Wires for digital and analog signals must be routed separately.

Control cables and power cables must be routed separately; the distance between
the control cable tray and the power cable tray must not be less than 300 mm
(11.8 in.).

If the control cable must pass through the power cable tray, the angle between the
cable trays must be as close to 90° as possible.

Do not mix AC and DC wires in the same cable bundle.

General Wire Categories on page 71 identifies general wire categories for

installing the PowerFlex 6000 drive. Each category has an associated wire group
number that is used to identify the required wire. Application and signal
examples, along with the recommended type of cable for each group, are
provided. A matrix providing the recommended minimum spacing between
different wire groups that run in the same tray or in a separate conduit is also
provided.

Control Signal Wire Shield Grounding

Guidelines for Drive Signal and Safety Grounds: when using interface cables
carrying signals, where the frequency does not exceed 1 MHz, for
communications with the drive, follow these general guidelines:
• Ground screen mesh around the entire circumference, rather than forming
a pigtail grounded only at one point.
• For coaxial cables with a single conductor surrounded by a mesh screen,
ground the screen at both ends.
• When using a multi-layer screened cable (that is, a cable with both a mesh
screen and a metal sheath or some form of foil), there are two alternative
methods:

Connect External Control Introduction

Signal Wiring
This section summarizes the control signal wiring from the remote DCS/PLC or
discrete control to the drive. General connections are detailed in Power Cabling
and Control Signal Wiring Details on page 73. Refer to the Electrical Drawings
for connection information specific See the drive being installed.

Analog and Digital I/O Overview

Four 4...20 mA analog input signals. One may be used for DCS with rotating
speed setting and three for backup. For detailed information, see Table 15 and
Table 16 on page 76.

Two 4...20 mA analog output signals for indication signals such as output motor
current and frequency. See Table 15 and Table 16 on page 76.

Sixteen passive dry contact inputs (internal 24V DC power supply) start/stop
and reset controls. For detailed information, see Table 15 and Table 16 on
page 76. These inputs are scalable depending on user requirements.

Twenty dry contact outputs: including nine active dry contact outputs with a
capacity of not more than 20W for indication (backup), and 11 passive dry
contact outputs powered by the drive with a capacity of 220V AC/5A for DCS
status/fault indication. For detailed information, see Table 15 and Table 16 on
page 76. These outputs are scalable depending on user requirements.

The drive is provided with dry contact outputs (1 N.O. with a capacity of
220V AC/5 A, valid when closed) which trigger the user-provided medium
voltage circuit breaker for interlock with the user-provided medium voltage
switch cabinet. For detailed information, see Table 15 and Table 16 on page 76.

Modbus RTU interface is supplied as standard (other communication interfaces

including Modbus TCP, Modbus Plus, EtherNet/IP™, and PROFIBUS are
provided as options). For detailed information, see Figure 46 on page 75.

Wiring Routing and Connection

The control signal wiring enters the drive through the same opening as the
control power wiring in the LV Control Cabinet (Figure 34 or Figure 35).

The wiring terminates either to the DTB1 or DTB2 terminal block strips on
either side of the LV Control cabinet (Figure 36). See Figure 45 or Figure 46 for
general information. See Electrical Drawings for actual connection points.

Chapter 2 Drive Electrical Installation

Connect Electrical Safety Introduction

Interlock Circuit to Input
Circuit Breaker The electrical safety interlock circuit is part of the overall control signal wiring
activity. However, it is mentioned separately in this document due to its critical
importance related to the safe operation of the drive and personnel safety.

The circuits that are connected between the drive and the input circuit breaker:
• allow the drive to trip the input circuit breaker if a drive cabinet door is
opened. This applies to the cabinet doors where medium voltage is
present. The LV Control cabinet door can be opened while the drive is
energized.
• allow the drive to prevent the input circuit breaker from closing when
required.
• indicate to the drive when the input circuit breaker is closed.

MV Door Safety Interlock

If the MV cabinet door is opened, the Allen-Bradley Guardmaster® Limit Switch

(440P-CRPS11D4B) on the cabinet door will actuate. The drive will send a trip
signal to the input circuit breaker to disconnect the medium voltage power
supply to the drive.

ATTENTION: The door position interlock is a safety feature. It must not be used
solely as a part of the plant operation process to ensure that the drive has been
disconnected from input medium voltage. Keep the medium voltage doors
locked as standard practice. Always go to the input circuit breaker feeding the
drive to verify if it is open. Lock out and tagout the input circuit breaker before
performing any work on the drive or bypass units.

Figure 37 - Interlock for Cabinet Doors

Door Position Limit Switch

54 Rockwell Automation Publication 6000-IN006H-EN-P - October 2020

 Drive Electrical Installation Chapter 2

When the doors of the Power Module/LV Control Cabinet or Isolation

Transformer Cabinet are not closed, when the drive is being maintained or when
the control power switch is not closed, the drive will not send a signal allowing
the input circuit breaker to close; this is wired as a permissive contact in the input
circuit breaker’s closing circuit so that the input circuit breaker cannot close.

Wire Routing and Connection

The electrical safety interlock control signal wiring enters the drive through the
same opening as the control power wiring in the bottom of the LV Control
Cabinet (Figure 34 or Figure 35).

The wiring terminates to the X1 terminal block strip on the right side of the LV
Control cabinet (Figure 36). See Figure 45 or Figure 46 for general information.
See Electrical Drawings for actual connection points.

Power Cable Interconnection Figure 38 provides a three-line drawing overview of the power cable
interconnections between the power modules (PC XX) in the Power Module/
Overview LV Control cabinet and the secondary windings of the isolation transformer in
the Isolation Transformer cabinet. The number of power modules is dependent
solely on output (motor) voltage:
• 9 power modules for 2.3/2.4/3.0/3.3 kV
• 12 power modules for 4.0/4.16 kV
• 15 power modules for 6.0 kV
• 18 power modules for 6.6/6.9 kV
• 24 power modules for 10 kV
• 27 power modules for 11 kV

It also shows the connection point from the U, V, and W motor output phases
from the power module array to the voltage sensing board cables and the motor
cables.

The isolation transformer secondary windings as shown do reflect the actual

orientation on the isolation transformer.

The Power Module/LV Cabinet orientation is optimized for drawing clarity. To

better understand the physical orientation, the components and connections that
are shown in the Power Module/LV Control Cabinet would be rotated 90º
counter clockwise. The U phase is the top horizontal row, the V phase is the
middle horizontal row, and the W phase is the bottom horizontal row.

Connect Isolation Introduction

Transformer Secondary
The isolation transformer’s three-phase primary coils are oriented A, B, and C
Power Cables from left to right, as viewed from the front. The secondary windings are also
divided into three principal sections from top to bottom. The upper third are to
feed the power modules in the U output phase. The middle third are to feed the
power modules in the V output phase. The bottom third are to feed the power
modules in the W output phase (Figure 39).

The secondary windings are brought out to corresponding vertical isolated stand-
offs on the body of the transformer (orientated U, V, and W from left to right as
viewed from the front). See Figure 40.

Each secondary winding set will have a designated U, V, and W terminal

connection. For example, (from top to bottom and left to right) the terminals
from the first winding set are 1W, 1V, and 1U, the terminals from the next
winding set are 2W, 2V, and 2U, and so on.

As shown in Figure 38, the first winding set (1U, 1V, and 1W) will connect to the
three-phase input power connection of the first power module in the U motor
phase array (PCA1), the second winding set will connect to the second power
module in the U motor phase array (PCA2), and the third winding set will
connect to the third power module in the U motor phase array (PCA3). The
next three winding sets connect to the power modules in the V motor phase array.
The remaining three winding sets connect to the power modules in the W motor
phase array.

Figure 38 shows 3.0/3.3 kV configuration. The 6.0/6.6 kV and 10 kV

configuration have more power modules and therefore have more corresponding
isolation transformer secondary windings. The concept is the same—the top
third of the winding sets feeds the power modules in the U phase, the middle
third feeds the power modules in the V phase, and the bottom third feeds the
power modules in the W phase.

Rockwell Automation Publication 6000-IN006H-EN-P - October 2020 59

Chapter 3 Drive Electrical Interconnection

Each three-phase secondary winding set of the isolation transformer has three
individual single-phase power cables connecting its output to the three-phase
power input of its corresponding power module.

Drives are shipped split with an Isolation Transformer cabinet and a Power
Module cabinet, and connection at the site is needed. The power cables connect
to the secondary winding termination in the Isolation Transformer. All cables can
be connected from the front of the cabinet.

Line and Load Cable Sizes

The data in the following tables are informative only; do not base final design
criteria solely on this data. Follow national and local installation codes, industry
best practices, and cable manufacturer recommendations. As cabling methods
can vary widely, maximum cables sizes do not account for the size of the conduit
hub.

(1) Cable sizes are based on overall dimensions of compact-stranded three-conductor shielded cable (common for industrial cable tray
installations). Maximum sizing stated accounts for minimum rated cable insulation requirements and the next higher-rated cable
(that is, 8 kV is not commercially available in many areas of the world, therefore Rockwell Automation provides an 8 kV (minimum
rating) and a 15 kV rating, when applicable. Enclosure openings accommodate the thicker insulation on the higher-rated cable. IEC
ratings show the equivalent to the NEMA sizes. The exact cable mm2 size that is shown is not commercially available in many cases;
use the next smaller standard size.

(2) Minimum cable bend radius recommendations vary by national codes, cable type, and cable size. Consult local codes for guidelines
and requirements. General relationship of cable diameter to bend radius is typically between 7x...12x (for example, if the cable
diameter is 1 in. [2.54 cm] the minimum bend radius could range between 7...12 in. [18.8...30.48 cm]).

(3) As cabling methods can vary widely, maximum cable sizes that are shown do not account for the size of the conduit hub. Verify size
of conduit hubs against the “Drive enclosure openings” shown.

(1) Cable sizes are based on overall dimensions of compact-stranded three-conductor shielded cable (common for industrial cable tray
installations). Maximum sizing stated accounts for minimum rated cable insulation requirements and the next higher-rated cable
(that is, 8 kV is not commercially available in many areas of the world, therefore Rockwell Automation provides an 8 kV (minimum
rating) and a 15 kV rating, when applicable. Enclosure openings accommodate the thicker insulation on the higher-rated cable. IEC
ratings show the equivalent to the NEMA sizes. The exact cable mm2 size that is shown is not commercially available in many cases;
use the next smaller standard size.

(2) Minimum cable bend radius recommendations vary by national codes, cable type, and cable size. Consult local codes for guidelines
and requirements. General relationship of cable diameter to bend radius is typically between 7x...12x (for example, if the cable
diameter is 1 in. [2.54 cm] the minimum bend radius could range between 7...12 in. [18.8...30.48 cm]).

(3) As cabling methods can vary widely, maximum cable sizes that are shown do not account for the size of the conduit hub. Verify size
of conduit hubs against the “Drive enclosure openings” shown.
