Installation and startup

NOTICE!

Installation, operation, and maintenance must be carried out by qualified personnel.

Please note the package leaflet during installation:

The package leaflet is part of the device's scope of delivery. The documents are available as PDF files
and can be downloaded from the manufacturer's website.

•

When configuring the device as per the safety requirements according to the operating mode table,
observe the switch positions that are not admissible for safety-related applications

•

Connect the device according to the installation instructions

•

Check the functionality of the device with a connected sensor or switch with resistance circuit for cor-
rect function

•

Start up the safety circuit and test for correct function

•

Avoid inadmissible currents by switching an external 4-A(T) fuse on the contact side of the relay

•

Check the external temperature monitoring in an installed state

•

Install the device in a control cabinet with a key lock and at least IP54

•

Test the used voltage supply in order to be able to compensate for brief interruptions (

≤

20 mA)
