of a short circuit!
According to DIN VDE 0100-430, devices for protection against a short circuit can be
omitted for the coupling of terminals WA and WB if the wiring is carried out in such a manner as to reduce
the risk of a short circuit to a minimum. (A short-circuit-proof and earth-fault-proof wiring is recommen-
ded). The connecting lines WA and WB to the system to be monitored must be designed as spur lines. No
load current may be conducted through the terminals.
