Electrical installation
Chapter overview
This chapter describes the electrical installation procedure of the DCS880.
WARNING
A qualified electrician may only carry out the work described in this chapter. Follow the
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 was already connected to the mains, wait for 5 min. after disconnecting mains
power.
Further information is available in the

Checking the insulation of the drive
Every converter has been tested for insulation between the main circuit and the chassis
(2500 V rms 50 Hz for 1 second) at the factory. Therefore, do not make any voltage
tolerance or insulation resistance tests (e.g. hi-pot or megger) on any part of the converter.
Check the insulation of the drive as follows.
WARNING
Check the insulation before connecting the drive to the mains. Make sure that the drive is
disconnected from the mains (input power).
1. Check that the motor cables are disconnected from the converter output terminals C1,
D1, F+ and F-.
2. Measure the insulation resistances of the motor cable and the motor between each
circuit (C1, D1) / (F+, F-) and the Protective Earth (PE) by using a measuring voltage of
1 kV DC. The insulation resistance must be higher than 1 MOhm.
