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. Obey the
Safety instructions
(page 9) in this manual.
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 was connected to the input power, wait for 5 minutes after you disconnect
the input 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 was tested for insulation between
the main circuit and the chassis at the factory. 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
you connect it to the drive.
