NOTE
Layout of data cables
Use shielded data cables with twisted-pair wires.
■
Implement the shielding design correctly and completely.
■
To avoid interference, e.g., from switching power supplies, motors, clocked drives,
■
and contactors, always use cables and layouts that are suitable for EMC.
Do not lay cables over long distances in parallel with voltage supply cables and
■
motor cables in cable channels.
The IP enclosure rating for the device is only achieved under the following conditions:
The cables plugged into the connections are screwed tight.
■
Any electrical connections that are not being used must be fitted with protective
■
caps that are screwed tight (as in the delivery condition).
Any other lids present must be closed and lie flush on the device.
■
If these instructions are not complied with, the IP enclosure rating for the device is not
guaranteed!

NOTICE
Risk of damage to the device!
The device can become damaged if it is connected to a voltage supply that is already
switched on.
•
Only connect the device when the supply cable is de-energized.
The device must be connected to a power supply unit with the following properties:
• Supply voltage DC 10.8 V – 28.8 V (SELV/PELV as per currently valid standards)
•
Electricity source with at least 3 W power
To ensure protection against short-circuits/overload in the customer's supply cables,
the wire cross-sections used must be appropriately selected and protected.
