Checking motor and motor cable insulation

WARNING! Check the motor and motor cable insulation before connecting the drive
to input power. For this test, make sure that motor cables are NOT connected to the
drive.
1. Complete motor cable connections to the motor, but NOT to the drive output
terminals (U2, V2, W2).
2. At the drive end of the motor cable, measure the insulation
resistance between each motor cable phase and Protective
Earth (PE): Apply a voltage of 1 kV DC and verify that
resistance is greater than 1 Mohm.
