4.2 Mounting in control cabinet

When the CIU unit is mounted in a control cabinet
containing a frequency converter, it is especially
important to ensure an EMC-correct installation of
both the CIU unit, CIM module and frequency
converter.
The following rules must therefore be observed:
• All cable screens must be connected to earth.
If it is not possible to use cable clamps, the
stripped part of the cable screen must be as short
as possible to reduce the impedance at high
frequencies.
• All units in the control cabinet must be connected
to earth.
Mounting on DIN rail
The CIU unit is prepared for mounting on a 35 mm
DIN rail (EN 50022).
1. Fix the DIN rail clip supplied on the CIU unit.
See the instructions on the CIU unit.
2. Fit the CIU unit by hooking the top on the DIN rail
and clicking the bottom onto the rail. See fig. 3.
