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. Measure the insulation resistance between each
phase conductor and the Protective Earth conductor
using a measuring voltage of 500 V DC. The
insulation resistance of an ABB motor must exceed
10 Mohm (reference value at 25 °C or 77 °F). For the
insulation resistance of other motors, please consult
the manufacturer’s instructions.
Note:
Moisture inside the motor casing will reduce
the insulation resistance. If moisture is suspected, dry the motor and repeat the
measurement.
