Unit description
Bestimmung/Gertebesc hreibung NOT-AUS , Schutzt, Lichtsc hr_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
` Light beam devices
Safety features
][Sicherheitseigenschaften Schaltgerät_allgemeiner 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.

Please note:
` Information given in the “Technical
details” must be followed.
` Outputs 13-14, 23-24 are safety
contacts.
` To prevent contact welding, a fuse
should be connected before the
output contacts (see technical details).

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