Mounting and installation
Installing the motor power cable
EMC-optimal installation in system and control cabinet
With regenerative supply units, use shielded lines with the shield grounded at
both ends for the connection between supply unit and mains choke.
●
Use shielded motor power cables or run motor power cables in a shiel‐
ded duct
●
Use the shortest possible motor power cables
●
Ground motor power cable shield at both ends over the largest possible
surface area to establish a good electrical connection
●
Run shielded motor lines inside the control cabinet
●
Do not use any steel-shielded lines
●
The shield of the motor power cable cannot be interrupted by mounted
components, such as output chokes, sine filters or motor filters
General information
For EMC-optimal installation, it is recommended to spatially separate the
area free from interference (mains connection) from the area prone to inter‐
ference (drive components), as shown in the figures below.
Recommendation: For EMC-optimal installation in the control cab‐
inet, use a separate control cabinet panel for the drive compo‐
nents.
Division into areas (zones)
Sample arrangements in the control cabinet: See section
sign according to interference areas - exemplary arrangements, page
There are three areas:
1. Control cabinet area free from interference (area A):
This includes:
●
Supply feeder, input terminals, fuse, main switch, mains side of
mains filter for drives and corresponding connecting lines
●
Control voltage or auxiliary voltage connection with power supply
unit, fuse and other parts unless connection is run through the
mains filter of the AC drives
●
All components that are not electrically connected to the drive sys‐
tem
2. Area prone to interference (area B):
●
Mains connections between drive system and mains filter for
drives, mains contactor
●
Interface lines for drive controller
3. Area highly prone to interference (area C):
●
Motor power cables including single cores
Never run lines from one of these areas along lines from another area to
eliminate any unwanted interference injection from one area to the other and
jumper the filter with regard to high frequency. Use the shortest possible con‐
necting lines.
Recommendation for complex systems: Install drive components in one cabi‐
net and the control units in a second, separate cabinet.
