Single-channel operation: no re-
dundancy in the input circuit, earth
faults in the reset circuit are detect-
ed.
Power: Supply voltage
Reset/start: Reset circuit Y1-Y2
Input: Input circuits A1-L+
Output safe: Safety contacts 13-14,
23-24, 33-34
Information given in the “Technical
details” must be followed.
Outputs 13-14, 23-24, 33-34 are
safety contacts, output 41-42 is an
auxiliary contact (e.g. for display).
To prevent contact welding, a fuse
should be connected before the
output contacts (see technical de-
tails).

Use copper wire that can withstand
60/75 °C.
Sufficient fuse protection must be
provided on all output contacts with
capacitive and inductive loads.

Automatic start: Unit is active once
the input circuit has been closed.
Manual reset: Unit is active once
the input circuit is closed and then
the reset circuit is closed.
Output aux: Auxiliary contacts 41-
