Electrical installation
What this chapter contains
This chapter describes the electrical installation procedure of the drive.
WARNING! The work described in this chapter may only be carried out by a qualified
electrician. Follow the Safety instructions on the first pages of this manual. Ignoring
the safety instructions can cause injury or death.
Make sure that the drive is disconnected from the mains (input power) during
installation. If the drive is already connected to the mains, wait for 5 min after
disconnecting mains power.
Checking the insulation of the installation
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.
Supply cable
Check the insulation of the supply (input) cable according to local regulations before
connecting to the drive.
