Checking the insulation of the assembly
Drive
WARNING!
Do not make any voltage tolerance or insulation resistance
tests on any part of the drive as testing can damage the drive.
Every drive is tested for insulation between the main circuit and the chassis
at the factory. Also, there are voltage-limiting circuits inside the drive which
cut down the testing voltage automatically.
Input power cable
Check the insulation of the input cable according to local regulations before
connecting it to the drive.
Motor and power cable insulation
• Check that the motor cable is connected to the motor, and disconnected from the
drive output terminals U2, V2 and W2.
• Measure the insulation resistance between the phase conductors and between
each phase conductor and the Protective Earth conductor.
Use a measuring voltage of 1000 V DC. The insulation resistance of an ABB
motor must exceed 100 Mohm (reference value at 25 °C or 77 °F). For the
insulation resistance of other motors, consult the manufacturer’s instructions.
Note
: Moisture inside the motor casing reduces the insulation resistance. If
moisture is suspected, dry the motor and repeat the measurement.
