* Each ex-magnet has to be individually fused, with the fuse installed upstream of the magnet.

You can find more information in the manual of the magnets.

On site, the integration of a gas warning system must be checked by the ATEX representative

on the basis of explosion protection guidelines.

** Please refer to the Zener barrier manual for the detailed connection diagram.

Electrical Connection and Installation of an Ex-Proof

Hold-Open System with RZ-24 - cont.

The following wiring examples apply when the components of points 3b

and 6 are used. If for example other fire detectors (e.g. for installation

outside the hazardous area) are used, please contact us.

A hand release switch mounted outside the hazardous area, has to

be connected so that the Zener barrier is placed between it and the

hazardous area.

IMPORTANT: In case of an alarm the RZ-24 will completely electrically

isolate the control system of the door operator!
