Table 9 

 
The terminals must be properly tightened according to the size of the bolds. 
 
Temperature switches are optionally foreseen on both the Lo and Zo elements for the detection of a 
possible over-heating.  In that case, for each element, two voltage-free contacts are available : 
 
 

Terminals Connection 

A1 - A2 

Normally open contact ‘Warning’ (165°C) 

D1 - D2 

Normally closed contact ‘Alarm’ (190°C) 

 

 

 

Table 10

 

 

These contacts are connected on two small terminal boards ( Fig. 2 - "9" ). 
They are foreseen for a maximum current of 5A and a maximum voltage of 230V AC. 

 
 

 

For obvious safety reasons, the energising of the filter can only happen once the housing is 
perfectly secured. 
 
During the energising of the filter, the loads downstream the CleanWave

®

 filter will also be fed. It is 

the technician's responsibility to check that the downstream installation can safely be 
energised. 
 
Once the filter energised, the displays on the front side (IP21 version only) should indicate some 
upstream and downstream currents.
