Connecting cables
Note
Use copper cables at connectors with terminal connections
Use copper (Cu) cables for all supply lines that are connected to the device with terminals,
e.g. 24 V DC power supply cables to the 24 V DC power supply connectors.
Use only shielded standard cables as data cables, order information is available in the
section "Accessories (Page 25)".
Note
Separate SELV/PELV circuits from other electric circuits or isolate the wires.
The wiring of SELV/PELV circuits must either be separated from the wiring of other
non-SELV/PELV electric circuits, or the insulation of all conductors must be rated for the
higher voltage. Alternatively, a grounded shield or additional insulation must be installed
around the wiring for SELV/PELV circuits or the other electric circuits, based on
IEC 60364-4-41.
