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 - AC/DC-Gerte_PNOZ
The tranformer is short circuit-
proof. An electronic fuse is used on
a DC supply.

Please note:
Information given in the “Technical
details” must be followed.
Outputs 13-14, 23-24, 33-34 are
safety contacts, outputs 41-42 are
auxiliary contacts (e.g. for display).
To prevent contact welding, a fuse
should be connected before the
output contacts (see technical details).
Calculation of the max. cabling runs
in the input circuit:

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

Installation
Montage_PNOZ_X
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).

Service life graph
Lebensdauerkurve_Rela is_Text vor Kurv e
The service life graphs indicate the
number of cycles from which failures
due to wear must be expected. The
wear is mainly caused by the electrical
load; the mechanical load is negligible.
Lebensdauerkurve_Relais_Text nach Kurve_SIR_SLR Bsp
Example
Inductive load: 0,2 A
Utilisation category: AC15
Contact service life: 4,000,000 cy-
cles
Provided the application requires fewer than 4,000,000 cycles, the PFH value (see technical details) can be used
in the calculation.
To increase the service life, sufficient
spark suppression must be provided
on all output contacts. With capacitive
loads, any power surges that occur
must be noted. With contactors, use
freewheel diodes for spark suppression.
