PRELIMINARY INSPECTION

[√] Visually check the motor integrity, in order to find possibile damages due to transportation.
[√] Check power and voltage according to the application.
[√] Manually check that the shaft can rotate.
[√] Check the insulation resistance with a megger before installation: referring to a brand new
motor, the resistance must be over 500 Mohm.

TRANSPORT AND STORAGE

• Store motor in original package until assembly.
• Under no circumstances may the motor be stored as temperatures
above +50° C since this can lead to filling liquid leakage and
premature motor failure.
TOPPING THE MOTOR FLUID
