Measure the insulation resistance of the motor windings

(each phase to ground). Insulation resistance requirement for

Cold motor (10..40 °C): ≥ 5 MΩ

Warm motor (40 °C or more): ≥ 1 MΩ

If insulation resistance is less that requirement the motor

shall be dried.

Reconnect the motor cables and check the thightness of the

other cables.
