Installation
][Montage_PNOZsigma
Install base unit without contact expander module:
` Ensure that the plug terminator is
inserted at the side of the unit.
Connect base unit and PNOZsigma
contact expander module:
` Remove the plug terminator at the
side of the base unit and at the contact expander module.
` Connect the base unit and the con-
tact expander module to the supplied connector before mounting
the units to the DIN rail.
Installation in control cabinet
` 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 (35 mm).
` When installed vertically: Secure
the unit by using a fixing element
(e.g. retaining brakket or end angle).
` Push the unit upwards or down-
wards before lifting it from the DIN
rail.

It is essential to consider the relay's

safety-related characteristic data is
only valid if the values in the service life
graphs are met.
All the units used within a safety function must be considered when calculating the safety characteristic data.

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
