described in this chapter. Obey the instructions in chapter Safety instructions. If

Checking the insulation of the assembly
Drive
Do not make any voltage tolerance 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.
Input cable
Check the insulation of the input cable according to local regulations before connecting it
to the drive.
