Electrical installation
What this chapter contains
The chapter tells how to check the insulation of the assembly and the compatibility
with IT (ungrounded) and corner-grounded TN systems as well as connect power
cables and control cables.
WARNING!
The work described in this chapter may only be carried out by a
qualified electrician. Follow the instructions in chapter
Ignoring the safety instructions can cause injury or death.
Make sure that the drive is disconnected from the input power during
installation. If the drive is already connected to the input power, wait for
5 minutes after disconnecting the input power.
Checking the insulation of the assembly
Drive
Do not make any voltage tolerance or insulation resistance tests (for example hi-pot
or megger) 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 power cable
Check the insulation of the input power cable according to local regulations before
connecting to the drive.
