Measuring the insulation
■
Measuring the insulation resistance 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 resistance of the input power cable
Before you connect the input power cable to the drive, measure its insulation resistance
according to local regulations.
■
Measuring the insulation resistance 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, commissioning or
maintenance work.
1.
Do the steps in section
Electrical safety precautions (page 21)
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 reduces the insulation resistance. If you think
that there is moisture in the motor, dry the motor and do the measurement again.

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, commissioning or
maintenance work.
