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.

][Verdrahtung_Si_unverz

Please note:

` Information given in the “Technical

details” must be followed.

` Outputs 13-14, 23-24 are safety

contacts.

` Use copper wire that can withstand

60/75 °C.

` Sufficient fuse protection must be

provided on all output contacts with
capacitive and inductive loads.

` To prevent contact welding, a fuse

should be connected before the
output contacts (see technical de­tails).

` The safety relay should be installed

in a control cabinet with a protec­tion type of at least IP54.

` Use the notch on the rear of the unit

to attach it to a DIN rail.

` Ensure the unit is mounted securely

on a vertical DIN rail (35 mm) by us­ing a fixing element (e.g. retaining
bracket or an end angle).
