The relay outputs are line voltage isolated from the light barriers; to IEC60664 -1 overvoltage
category III.
All emitters WGS4... and WLS4... and all receivers WGE4... and WLE4... can be connected.
The control unit is built only for the use inside of control cabinets. The Sheet-metal housing
can be snapped on to the TS 35 for mounting inside control cabinets. The control cabinet must
comply with degree of pollution 2 to IEC EN 60439-1 at least (This is normally IP 54). The
mounting rail TS 35 must be connected to the PE conductor.
