Measuring the insulation
Measuring the insulation is typically not required in North America.
■
Measuring the insulation of the drive
WARNING!
Do not do any voltage withstand or insulation resistance tests on any part of the
drive as testing can damage the drive. Every drive has been 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.
■
Measuring the insulation of the input power cable
Before you connect the input power cable to the drive, measure its insulation according
to local regulations.
■
Measuring the insulation of the motor and motor cable
WARNING!
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.
1. Do the steps in section
Electrical safety precautions (page 17)
before you start the
work.
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 insulation resistance of other motors, refer to the manufacturer’s instructions.
Note:
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.
