Measuring the insulation of the motor and motor cable
1. Follow the electrical safety precautions. See Electrical safety instructions in the hardware
manual.
2. Make sure that the motor cable is disconnected from the drive output terminals.
3. Measure the insulation resistance 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 be more than 100 Mohm (reference value at 25 C [77°F]). For the
EN
insulation resistance of other motors, refer to the manufacturer's instructions.
HI
टिप् प णी Moisture inside the motor casing reduces the insulation resistance. If you think
that there is moisture in the motor, dry the motor and do the measurement again.

Obey the safety instructions of the drive. If you ignore them, injury or death,
or damage to the equipment can occur. If you are not a qualified electrical
professional, do not do installation or maintenance work.
