Unit description
Bestimmung/Gertebeschreibung NOT-AUS, Schutz_PNOZ
The safety relay meets the requirements of EN 60947-5-1, EN 60204-1
and VDE 0113-1 and may be used in
applications with
E-STOP pushbuttons
Safety gates
Safety features
][Sicherheitseigenscha ften Schaltgerät_allgem einer Teil
The relay meets the following safety
requirements:
The circuit is redundant with built-in
self-monitoring.
The safety function remains effec-
tive in the case of a component failure.
The correct opening and closing of
the safety function relays is tested
automatically in each on-off cycle.
Sicherheitseigenschaften Zusatz - Sicherung DC_PNOZ
The unit has an electronic fuse.

][Verdrahtung_Si_verz
Please note:
Information given in the “Technical
details” must be followed.
Outputs 13-14, 23-24, 33-34, 57-58
are delay-on de-energisation safety
contacts.
To prevent contact welding, a fuse
should be connected before the
output contacts (see technical details).
Calculation of the max. cable runs
in the input circuit:

ance (see technical details)
/ km = cable resistance/km

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