● Serial connecting cables must be shielded. Place the shield on the metallic connector
housing. Also connect the shield to the shield rail. Do not connect the cable shield to a
ground pin of the connector.
● The connector housing and front plate of the boards do not provide adequate cable
shielding. Connect the cable shields at both ends to the shield rails in the cabinets. Always
use shielded analog signal cables, regardless of whether they are installed inside or outside
cabinets. In order to increase the effectiveness of the shielding, ground spare conductors at
both ends.
You should only use the pre-assembled cable sets supplied. These cable sets are marked at
both cable ends with the precise designation of the connection point at which you must connect
or plug in the cable.
Note
For more information, see the interconnection diagram in the circuit manual.
Please proceed as follows:
1. Connect the signal and power supply cables.
2. Connect the shield and secure the cable. You can find further information on this in the
“Electromagnetic compatibility" section.
3. Seal the cable routing according to the degree of protection required.

Connecting the auxiliary voltage
Connecting the 1 AC auxiliary voltage
Connect the 1 AC auxiliary voltage e.g. for SITOP, closed-loop control, open-loop control,
cabinet lighting, service sockets, anti-condensation heating etc. to the relevant terminal blocks.
The maximum cross section of the cables is 2.5 mm
2
.
You will find detailed information in the terminal diagram or in the circuit manual under
"Technical specifications and drawings."
Connecting the 3 AC auxiliary voltage
Connect the 3 AC auxiliary voltage for e.g. fans, precharging etc. to the relevant terminal
blocks. Information on the maximum cable cross-section is provided in the project
documentation.
With options C30 - C49, the auxiliary voltage can be drawn from the matching transformer.
You will find detailed information in the terminal diagram or in the circuit manual under
"Technical specifications and drawings."
