The trip signals of the U> stage is firmly wired
to output relay A and the trip signal of the U<
stage to output relay B. In addition, the follow-
ing functions can be selected with the switches
of the SGR switchgroup on the front panel of
the relay:
Configuration of

SGR/1 Routes the external blocking signal to stage U< 1
SGR/2 Routes the start signal of the U< stage to output relay D 1
SGR/3 Routes the start signal of the U> stage to output relay D 1
SGR/4 Routes the trip signal of the U< stage to output relay D 1
SGR/5 Routes the trip signal of the U< stage to output relay C 1
SGR/6 Routes the trip signal of the U< stage to output relay A 1
SGR/7 Routes the trip signals of the U> stage to output relay C 1
SGR/8 Routes the trip signals of the U> stage to output relay B 1
Circuit breakers can be controlled directly with
output relay A and B. This enables two circuit
breakers to be controlled at the same time or
separate trip output relays can be configured for
the overvoltage protection and the undervoltage
protection.
