Protecting the supply cables
To ensure protection against short-circuits/overload in the customer’s supply cables,
appropriately choose and protect the wire cross-sections used.
The following standards must be observed in Germany:
Observe applicable standards (Germany):
•
DIN VDE 0100 (part 430)
•
DIN VDE 0298 (part 4) and DIN VDE 0891 (part 1)
Connecting device without connection module
For a supply voltage of DC 12 V to 24 V ± 20%, protect the device with a separate 2 A
fuse.
b
Install the fuse in the supply circuit at the start of the supply cable.
