Following tools are required to install the electric machine:
•
Grease pump.
•
Ratchet torque wrench.
•
Hex head wrench kit with different metric sizes.
•
Socket wrench kit with different metric sizes.
•
Cable gland tightening tool. Size according to cable glands.
•
Cable skinning knife.
•
Crimping tool for cable lugs. Consult cable lug manufacturer for correct size.
•
Lifting slings with sufficient rated capacity.
•

Do not touch the electric machine during the insulation resistance check. Discharge the
electric machine afterwards.
Measure the insulation resistance of the electric machine before and after the installation of
the electric machine.
Use a voltage of 500 V in the insulation resistance test.
Measure the insulation resistance of the electric machine before and after the installation of the electric
machine. Because of the structure of the electric machine, it is possible that the stator is damaged during
the installation.
If the electric machine is in continuous use, it is recommended to do the insulation resistance test three
or four times a year.
The reference value of 150 MΩ must be exceeded in room temperature. Contact Danfoss representative if
the reference value is not exceeded. Reference value of 150 MΩ has to be exceeded at reference ambient
temperature 25°C (measured with 500 V
Allowed mounting positions
If the application is a moving work machine or similar, it is allowed to deviate from the
allowed mounting position for the duration of 30% of the work cycle. This applies to electric
machines with grease lubricated bearings.
