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