WARNING: The electrical panel is located under the coping plate. It is necessary to respect the minimum clearances 
given in section 7.3 in order to be able to connect the wires.

 

 

WARNING:  Installer has to provide a general circuit  breaker (for example  a  magnetothermic circuit  breaker) at the 
beginning of unit circuit system. 

 

WARNING: The supply voltage’s fluctuations cannot exceed ±10% of the nominal value. Should this tolerance not  be 
respected, please contact our technical department. 

 

WARNING:  The  power  supply  have  to  respect  the  listed  limits:  failing  this,  warranty  will  terminate  immediately. 
Before any operation on the unit, be sure that the power supply is disconnected. 
WARNING: The water flow switch (B component in the previous hydraulic circuit and factory installed) have ALWAYS 
to  be  connected  following  the  indications  listed  in  the  wiring  diagram.  Never  bridge  the  water  flow  switch 
connections  in  the  terminal  board.  Should  the  water  flow  switch  connections  altered  or  not  properly  made,  the 
guarantee will be invalidated. 

 

WARNING:  The  remote  control  panel  is  connected  to  the  water  chiller  by  means  of  no.4  wires  having  a  1,5  mm

2

 

section. The power supply cables have to be separated from the remote control wires. The maximum distance is 50m. 

 

WARNING: The remote control panel cannot be installed in areas with strong vibrations, corrosive gases, and excess 
of dirtiness or high humidity levels. Leave free the area near the cooling openings. 

7.8.1

 

Wiring terminal block 

 

Electrical wiring have to be done only by qualified personnel. 

The electrical connections have to be realized by qualified personnel.

 The terminal block is located under the cover  of the unit 

close to the side where the controller is positioned. To get access to the terminal block, please see the indications reported in the 
paragraph  7.8.2.  The  wiring  to  the  terminal  block  has  to  be  realized  in  accordance  to  the  below  notes  (the  drawing  is  for 
illustration). 
The  illustrations  below  are  for  the  corresponding  sizes  112T  RH  and  115T  RH,  as  for  the  other  models,  the  only  difference  is 
concerning the power supply input terminals. 

 

The connections indicated below are standard. Other connections are shown in the manual MCO of the on board control of MEX VS  
unit (see "TABLE OF CONFIGURATIONS ALLOWED TO USER AND INSTALLER"), depending on the configurations adopted.
