19. Servicing the product

19.1 Motor

If service is needed on the product, please contact 
Grundfos Service.

19.2 Pump

Service documentation is available in Grundfos 
Product Center 
(http://product-selection.grundfos.com/).
If you have any questions, please contact the 
nearest Grundfos company or service workshop.

20. Cleaning the product

In order to avoid condensation in the motor, let the 
motor cool down before spraying it with cold water.

21. Megging

Do not meg an installation incorporating MGE motors 
as the built-in electronics may be damaged.

22. Technical data, three-phase 

motors

22.1 Supply voltage 

Check that the supply voltage and frequency 
correspond to the values stated on the nameplate.

Recommended fuse size

3 x 380-480 V - 10 %/+ 10 %, 50/60 Hz, PE.

22.2 Leakage current (AC)

The leakage currents are measured without any load 
on the shaft and in accordance with EN 
61800-5-1:2007.

23. Inputs/outputs

Earth reference

All voltages refer to earth. All currents return to 
earth.

Absolute maximum voltage and current limits

Exceeding the following electrical limits may result in 
severely reduced operating reliability and motor life:
Relay 1:
Maximum contact load: 250 VAC, 2 A or 30 VDC, 2 
A.
GENI terminals: -5.5 to 9.0 VDC or less than 25 
mADC.
Other input/output terminals: -0.5 to 26 VDC or less 
than 15 mADC. 

DANGER

Electric shock

Death or serious personal injury
- Switch off the power supply to the motor 

and to the signal relay. Wait at least 5 
minutes before starting any work on the 
motor. Make sure that the power supply 
cannot be accidentally switched on.

DANGER

Magnetic field
Death or serious personal injury
- Do not handle the motor or rotor if you 

have a pacemaker.

WARNING

Electric shock

Death or serious personal injury
- Switch off the power supply to the motor 

and to the signal relay. Check that the 
terminal box cover is intact before 
spraying water on the product.
