Before You Begin 10/2008

Before You Begin Read and follow these precautions before performing any procedure with
this drive.
The word “drive” as used in this bulletin refers to the controller portion of the
adjustable speed drive as defined in the National Electrical Code (NEC).
.

DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
• Read and understand this manual before installing or operating the
Altivar 61 or 71 drive. Installation, adjustment, repair, and maintenance
must be performed by qualified personnel.
• The user is responsible for compliance with all international and national
electrical code requirements with respect to grounding of all equipment.
• Many parts of this drive, including the printed circuit boards, operate at
the line voltage. DO NOT TOUCH. Use only electrically insulated tools.
• DO NOT touch unshielded components or terminal strip screw
connections with voltage present.
• DO NOT short across terminals PA/+ and PC/– or across the DC bus
capacitors.
• Before servicing the drive:
— Disconnect all power, including external control power that may be
present.
— Place a “DO NOT TURN ON” label on all power disconnects.
— Lock all power disconnects in the open position.
— WAIT 15 MINUTES to allow the DC bus capacitors to discharge.
Then follow the “Bus Voltage Measurement Procedure” on page 11
to verify that the DC voltage is less than 42 V. The drive LED is not
an indicator of the absence of DC bus voltage.
• Install and close all covers before applying power or starting and
stopping the drive.

Failure to follow these instructions will result in death or serious

injury.

Electrostatic Precautions
CAUTION
STATIC SENSITIVE COMPONENTS
Circuit boards and option cards can be damaged by static electricity.
Observe the electrostatic precautions below when handling controller
circuit boards or testing components.

Failure to follow these instructions can result in injury or equipment

damage.

Observe the following precautions for handling static-sensitive components:

• Keep static-producing material such as plastic, upholstery, and
carpeting out of the immediate work area.
• Store static-sensitive components in protective packaging when they are
not installed in the drive.
• When handling a static-sensitive component, wear a conductive wrist
strap connected to the component or drive through a minimum of
1 megohm resistance.
• Avoid touching exposed conductors and component leads with skin or
clothing.

Inspecting the Spare Part Kits After receiving the ATV61/ATV71 spare parts kit:
• Ensure that the catalog number printed on the kit label is the same as
that on the packing slip and corresponding purchase order. Contact your
Schneider Electric representative if there are any errors.
• Remove the kit from its packaging and inspect it for damage. If any
damage is found, notify the carrier and your Schneider Electric
representative.
• To store the kit, replace any static-sensitive parts in their protective
packaging and store them at -25 to +70 °C (-13 to +158 °F).

WARNING
DAMAGED EQUIPMENT
Do not install or operate any equipment that appears damaged.

Failure to follow these instructions can result in death, serious

injury, or equipment damage.

10/2008 Installation Procedures

Installation Procedures
Power Removal and
Bus Voltage Measurement DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
Read and understand the precautions in “Before You Begin” starting on
page 6 before performing this procedure.

Failure to follow these instructions will result in death or serious

injury.

The DC bus voltage can exceed 1,000 Vdc. Use a properly rated
voltage-sensing device when performing this procedure. To measure the
DC bus voltage:
1. Disconnect all power.
2. Wait 15 minutes to allow the DC bus to discharge.
3. Measure the voltage of the DC bus between the PA/+ and PC/–
terminals to ensure that the voltage is less than 42 Vdc.These terminals
are clearly labeled on each drive.
4. If the DC bus capacitors do not discharge completely, contact your local
Schneider Electric representative. Do not repair or operate the drive.

CAUTION
IMPROPER DRIVE OPERATION
• If the drive is not turned on for a long period, the performance of its
electrolytic capacitors will be reduced.
• If the drive is stopped for a prolonged period, turn the drive on every two
years for at least 5 hours to restore the performance of the capacitors,
then check its operation.
• Do not connect the drive directly to line voltage. Increase the voltage
gradually using an adjustable AC source.

Failure to follow these instructions can result in injury or equipment

damage.

Installation Procedures 10/2008

Discharging Stored Energy in

Capacitors DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
• When the controller is damaged, voltage may remain on certain energy
storage capacitors after de-energization of the controller and discharge
of the main capacitor bank.
• Before working on or near assemblies containing energy storage
capacitors, verify that the capacitor voltages are less than 42 Vdc.
• The following assemblies have energy-storing capacitors:
— Filter board
— Rectifier snubber board
— Snubber capacitors
• Always check for the presence of voltage using a voltmeter set to the
1000 Vdc scale. When voltage is present, allow the voltmeter to
discharge the capacitor’s stored charge.

Failure to follow these instructions will result in death or serious

injury.

Capacitors are used throughout the drive as energy storage devices. Some
of the capacitors can store potentially lethal amounts of energy during
normal controller operation.
When power is removed from an undamaged controller, the stored energy
in these capacitors is automatically discharged to nonhazardous levels.
However, the discharge mechanisms in a damaged controller may not be
operating properly, and stored energy may be present on printed circuit
boards.
Do not touch traces on printed circuit boards, such as the line filter board
and rectifier snubber board, unless you have first checked for voltage with a
voltmeter!
To discharge the filter board capacitors, rectifier snubber board, and
snubber capacitors, use a voltmeter set to the 1000 Vdc scale. It will take
approximately 6.6 minutes for a 10 megohm input impedance voltmeter to
discharge a 10 microfarad capacitor from 700 V to less than 42 V. It will take
approximately 40 seconds for a 1 megohm input impedance voltmeter to
discharge a 10 microfarad capacitor from 700 V to less than 50 V.

DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
• Do not use a voltmeter to discharge stored energy on the DC bus
capacitors.
• If the energy on the DC bus capacitors remains greater than 42 Vdc
after 15 minutes, contact Product Support.

Failure to follow these instructions will result in death or serious

injury.
