Installing the device 

WARNING!

 ALWAYS PULL THE MAINS PLUG BEFORE OPENING THE CASING!

 

 

 

Unscrew the four screws on the edges of the case and screw on the basin through the two 

holes on the bottom side using the fastening screws provided. 

 
 

Electrical connection 

Only a trained electrician may provide the electrical connection in compliance with local 

guidelines. The sensor lines must not be laid in the same cable channel as the supply 
voltage. In a commonly used cable channel, appropriate shielding has to be provided. 

 

Caution: 

Only work on the inside of the control system when it is dead. The connections 

are to be put according to the marking of the clamps. 

 

Note:

 To provide protection from lightening, the system has to be grounded in accordance 

with the regulations. Sensor failures due to storms and static electricity are usually the result 
of improper grounding or overvoltage protection on the collector sensor. 

 

 

Pin configuration: 

 

 

When using the master-slave function, the data link must be connected in-phase to both units 
(data to data, ground to ground).
