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.

It is essential to consider the relay's
service life graphs. The relay outputs'
safety-related characteristic data is
only valid if the values in the service life
graphs are met.

The PFH value depends on the switch­ing frequency and the load on the relay
output.
If the service life graphs are not acces­sible, the stated PFH value can be

INFORMATION

A safety function's SIL/PL values are
not identical to the SIL/PL values of
the units that are used and may be dif­ferent. We recommend that you use
the PAScal software tool to calculate
the safety function's SIL/PL values.
