MGE-G, MLE-G Features and benefits

2. Features and benefits

The Grundfos MGE-G and MLE-G are standard asynchronous motors with integrated frequency
converter. The major features and benefits for the MGE-G and MLE-G motors are:

• Modular design. The choice among different functional modules and control panels enables
different variants
• Compact design
• Available with UL recognition cUR/US
• Plug connection for external wires enables easy service and installation
• Service set-up where mounting of control panels and functional modules will be carried out by
the service engineer. This will reduce the required stock of service parts.
• Factory-configured with the required application set-up, so the only set-up to be made at the
commissioning is setting the setpoint
• Can be operated by means of R100 and PC Tool E-Products
• Control based on sensor feedback to internal PI regulator
• Duty/stand by function
• Setpoint adjustable by means of external signal
• Digital inputs for external control
• Relay for warning, operation and fault
• Wide voltage range (380 - 480 V)
• The same MGE-G motor can be used for both 50 Hz and 60 Hz operation
• High speed operation
• IE2 and IE3 standard motor used
• Energy optimization
• Robustness.
The common features and benefits for E-motors in general described in the common information
also apply to MGE-G and MLE-G.

3. Main components
In order to give a good overview of the construction of an E-motor, we have chosen to split it up in
the five major components illustrated in the drawing below.
The components are not drawn to scale but intended to illustrate that the physical difference in size
is related to the power rating of the motor, see table below the drawing.

The power factor is defined as the ratio between active power and apparent power.
This ratio is normally called cosϕ. But cosϕ is only defined for sinusoidal voltages and currents.
When the mains is loaded by a frequency converter, the current input is not sinusoidal.
Therefore the term power factor is used instead.
Reference: See Common information, section 3. Frequency converter basics.

5.2 Label with pump configuration file number

The label with the pump configuration file number is placed on the inside of the terminal box cover.

MGE-G, MLE-G Identification

5.5 Type designation

The type designation is a unique specification of the E-motor type and model. The complete type
designation is thus the basis of the selection of drawings, spare parts, etc.
Note: The type designation is not sufficient for an unambiguous identification of a motor. The prod-
uct number of the motor must therefore always be stated together with the type designation when
enquiring or reordering.

5.6 Type key

5.6.1 MGE-G
The type key is general for MGE motors and explains what the codes of the type designation mean.

5.7 SAP material description

The SAP material description is mentioned in the product information as this description is used in
parts lists, etc. in SAP
Internal Grundfos staff will therefore typically work with the material description instead of the type
designation.
Note: The SAP material description is not sufficient for a clear identification of a motor. Conse-
quently, always state the product number of the motor together with the SAP material description
when enquiring or reordering.

The colour is black: NCS 9000 gloss 40 ±10.
Other colours than the black electro-coating are available.
The inner stator bore surface is corrosion protected by means of a liquid, and this combined with
the painted rotor surface makes the motor resistant towards high humidity.

Standard
On the basis of market experience Grundfos estimates that MGE-G and MLE-G motors fulfil climate
group ‘Moderate’ to DIN IEC 60 721, Part 2-1 for indoor and outdoor installation.
Motors provided with a coating on top of the electro-coating are still categorized as climate group
‘Moderate.

Drive end:
Motors are supplied with either single-row, deep-groove ball bearings with outer and inner rings
locked by means of lock rings or with angular contact bearings.
Non-drive end:
Motors are supplied with single-row, deep-groove ball bearings.
If the motor has a deep-groove ball bearing in the drive end, a corrugated spring washer will be fitted
between the bearing and the bearing end shield. If the motor has an angular contact bearing in the
drive end, one or two corrugated springs will be fitted between the bearing and the bearing end
shield.

MGE-G and MLE-G motors for CRE/CRNE/CRNE-S, CRKE, MTRE as from 4.0 kW (frame
sizes 112-132):
These motors have angular contact bearings in the drive end to absorb the outgoing axial forces
(pull).
MGE-G and MLE-G motors for CRNE-HS and CRNE-SF (frame sizes 112-132):
These motors are supplied with single-row deep-groove ball bearings in the drive end. Two corru-
gated springs are fitted between the bearing and the bearing end shield.
An angular contact bearing is fitted in the non-drive end to absorb the ingoing axial forces (thrust).
For information on bearing clearances, grease types, maintenance and lubrication intervals etc.,
see Common information, section 10.1.8 Bearings.
Bearing sizes for the individual E-motors and for various E-pump types appear from the product
range, see Common information.

8.1.13 Shaft end

The shaft end complies with IEC 60072-1 and EN 50347.

Approvals MGE-G, MLE-G

10. Approvals
10.1 UL approval
Both MGE-G and the MLE-G motors have the cURus approval.

UL = Underwriters’ Laboratories Inc.

UL approval is primarily required in the American market.
UL approval at component level facilitates approval of the final product and signals a certain quality
level of the component - in this case the motor.
Tests are carried out by the American testing insitute Underwriters’ Laboratories according to
UL1004 Standard for Electric Motors.
Underwriters’ Laboratories are authorized to issue UL and cUL approvals after carrying out an
approved test.
UL standards applying in the USA:
• UL508C Power Conversion Equipment
• UL1004 Electric Motors.

Recognized component marks issued by UL

UL and cUL approvals give the manufacturer the right to mark his product with a Recognized
Component Mark for the USA and Canada. The recognition mark is shown on the nameplate of the
motor, see figure below.
TM02 1594 1601

Fig. 38 Recognized component mark covering both the USA and Canada

These marks may be used on the motor as a component in a machine or a large system.

10.2 C-tick approval

EMC and C-tick

Fig. 39 C-tick approval mark covering Australia

All E-pumps marked with the C-tick logo fulfil the requirements for EMC in Australia and New
Zealand.
The C-tick approval is based on the EN-standards and the units are therefore tested according
to the European standard EN 61 800-3.
Only E-pumps with MGE-motors are marked with C-tick.
The C-tick only covers emission.

12.3 Air humidity

Maximum air humidity: 95 %
If the air humidity is constantly high and above 85 %, the drain holes in the drive-end flange should
be opened.
For further information, see Common Information.

12.4 Number of starts

The number of starts and stops via the mains voltage must not exceed 4 times per hour. When the
E-motor is switched on via the mains, it will start after approx. 5 seconds. If a higher number of
starts and stops is desired, the digital input for external start/stop must be used when starting/stop-
ping the pump. When the E-motor is started/stopped via an external on/off switch, it will start
immediately.

12.5 Cooling
The motor is cooled according to IEC 34-6, IC 0141, i.e. surface cooled by means of a fan mounted
on the motor shaft (fan-cooled).
TM02 6808 2303

Operating conditions MGE-G, MLE-G

12.8 EMC
Emission:
Comply with the limits in EN 61 800-3 for the first environment (residential areas), unrestricted dis-
tribution, corresponding to CISPR11, group 1, class B.

Immunity:
Fulfil the requirements for both the first and the second environment according to EN 61 800-3.
Precautions such as extra EMC filters are not required for most of our products but 7.5 kW 2-pole
and 5.5 kW 4-pole MGE-G motors need an EMC filter to fulfil the requirements. The product number
for the EMC filter is: 96041047.
In order to achieve EMC-correct installation, the cable connections to the E-motor should be taken
into consideration. Cable connections are described in 13.2.10 Connections.

Installation MGE-G, MLE-G

13.2 Electrical installation

Note: The user or the installer is responsible for the installation of the correct earthing and protec-
tion according to current national and local standards. All operations must be carried out by a
qualified electrician.
Note: In order to maintain the UL/cUL approval, additional installation procedures must be followed,
see 13.4 Installation in the USA and Canada on page 158.
Warning!
All electric supply circuits must always be inter-
rupted before working in the motor terminal box.

Never make any connections in the motor

terminal box unless the electricity supply has
been switched off for at least 5 minutes.

13.2.1 Protection against electric shock – indirect contact

The motor must be earthed and protected against

indirect contact in accordance with national
regulations.
Protective earth conductors must always have a yellow/green (PE) or yellow/green/blue (PEN)
colour marking.
Note: As the leakage current of 4 kW to 7.5 kW motors is > 3.5 mA, these motors must be
connected to especially reliable/sturdy earth connections.

Leakage current

Motor size Leakage current

[kW] [mA]
0.75 to 3.0 (supply voltage < 460 V) < 3.5
0.75 to 3.0 (supply voltage > 460 V) <5
4.0 to 7.5 > 3.5

The leakage currents are measured in accordance with EN 61800-5-1.

The leakage current of the individual motor sizes can be found in section
18.2.2 Leakage current.
EN 50 178 and BS 7671 specify the following:

Leakage current > 3.5 mA:

The motor must be stationary and installed permanently. Furthermore, it must be connected
permanently to the electricity supply.
• The earth connection must be carried out as duplicate conductors.

Leakage current > 10 mA:

If the installation includes several mains-connected units and the total leakage may be
> 10 mA, the demands on the earth connection are tightened.
The motor must be stationary and installed permanently. Furthermore, it must be connected
permanently to the electricity supply.
In addition, observe the tightened precautions as regards earth connection.
Use one of the following installation examples:
• A single protective earth conductor with a cross-sectional area of 10 mm².
• Separate duplicate conductors each with a minimum cross-sectional area of 4 mm².
• Duplicate (protective earth) conductors in a multicore cable. One of the conductors may be the
metallic armour or sheath of the cable.
• A protective earth conductor contained in a cable conduit, trunking or cable tray so forming a
duplicate conductor.

1 April 2011/PI-081 152

MGE-G, MLE-G Installation

13.2.2 Mains switch

The motor must be connected to an external all-pole mains switch with a contact separation of at
least 3 mm in each pole according to IEC 364.

13.2.3 Fuse, back-up fuse

Recommended fuse size

Motor size Min. Max.

[kW] [A] [A]
0.75 to 3.0 10 16
4.0 to 5.5 16 16
7.5 25 32
Standard as well as quick-blow or slow-blow fuses may be used.

13.2.4 Additional protection

If the motor is connected to an electric installation where an earth-leakage circuit breaker is used
as additional protection, this circuit breaker must be of the type:
• which is suitable for handling leakage currents and cutting-in with short pulse-shaped leakage.
• which trips out when alternating fault currents and fault currents with DC content, i.e. pulsating
DC and smooth DC fault currents, occur.
For these motors use an earth leakage circuit breaker type B. This circuit breaker must be marked
with the following symbols:

ELCB

For more information about earth-leakage circuit breakers, see Common information,
section E-motors and earth-leakage circuit breakers (ELCB).
Note: When an earth-leakage circuit breaker is selected, the total leakage current of all the
electrical equipment in the installation must be taken into account.

13.2.5 Supply voltage

• 3 x 380-480 V ±10%, 50/60 Hz, PE.
The supply voltage and frequency are marked on the motor nameplate. Please make sure that the
motor is suitable for the electricity supply on which it will be used.
The wires in the motor terminal box must be as short as possible. Excepted from this is the
protective earth conductor which must be so long that it is the last one to be disconnected in case
the cable is inadvertently pulled out of the cable entry.

If the supply cable is damaged, it must be

replaced by the manufacturer, the
manufacturer's service partner or similarly
qualified persons in order to avoid a hazard.

13.2.6 Motor protection

The motor requires no external motor protection. The motor incorporates thermal protection against
slow overloading and blocking (IEC 34-11: TP 211).

13.2.7 Protection against mains voltage transients

The motor is protected against mains voltage transients in accordance with EN 61 800-3.

13.2.8 Protection against phase unbalance

In order to ensure correct motor operation in cased of phase unbalance, connect the motor to an
electricity supply with a quality corresponding to IEC 60 146-1-1, class C. This also ensures long
life of the components.

13.2.9 Start/stop of motor

The number of starts and stops via the mains voltage must not exceed 4 times per hour. When the
motor is switched on via the mains, the motor will start after approx. 5 seconds.
If a higher number of starts and stops is desired, use the input for external start/stop when starting
the motor. When the motor is started via an external on/off switch, the motor will start immediately.

13.2.10 Connections
Fig. 45 below shows the connection terminals of
• external potential-free contacts for start/stop
• digital functions
• external setpoint signal
• sensor signal
• GENIbus
• relay signal.
Note: If no external on/off switch is connected, short-circuit terminals 2 and 3 using a short wire.
Note: As a precaution, the wires to be connected to the following connection groups must be
separated from each other by reinforced insulation in their entire lengths:
1. Input/output (external start/stop, digital functions, setpoint and sensor signals, terminals
1-13, and bus connection (optional), terminals B, Y, A).
All inputs (group 1) are internally separated from the mains-conducting parts by reinforced
insulation and galvanically separated from other circuits. All control terminals are supplied
by protective extra-low voltage (PELV), thus ensuring protection against electric shock.
2. Signal relay (terminals NC, C, NO).
The output (group 2) is galvanically separated from other circuits. A maximum supply volt-
age of 250 V or protective extra-low voltage can be connected to the output as desired.
3. Mains supply (terminals L1, L2, L3, PE).
A galvanically safe separation must fulfil the requirements for reinforced insulation including
creepage distances and clearances specified in EN 60 335.
