6.6 Laying the signal lines
Malfunction due to common cable installation
Malfunctions can occur in the converter if cables with differing voltage levels are laid together
with internal cables in one cable duct in the cabinet.
● Do not run cables coming from the outside, for example to the terminal strips, together with
Ensure that the following instructions are complied with:
● All signal lines must be shielded. The cable shield should be braided, because cables
● Clamp the shield of incoming analog and binary cables to the shield busbar at the entry point
● Serial connecting cables must be shielded. Place the shield on the metallic connector
● The connector housing and front plate of the boards do not provide adequate cable
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
3. Seal the cable routing according to the degree of protection required.

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.
