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 the following rating:
•
Lector621: 2 A
•
Lector621 ECO: 0.8 A
b
Install the fuse in the supply circuit at the start of the supply cable.
Connection with connection module
The supply voltage for the device is protected as follows in the connection modules in
the circuit after switch S1:
