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
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 supply (input power) during
installation. If the drive is already connected to the supply, 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 (e.g. 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.
Supply cable
Check the insulation of the supply (input) cable according to local regulations before
connecting to the drive.
Motor and motor cable
Check the insulation of the motor and motor cable as follows:
1. Check that the motor cable is connected to the motor, and disconnected from the
drive output terminals U2, V2 and W2.
2. Measure the insulation resistance between each phase and the motor PE
conductor by using a measuring voltage of 1 kV DC. The insulation resistance
must be higher than 1 Mohm.
