Instructions 

2.1

 

Mounting 

The transducer is mounted on a 35mm DIN rail on a wall or device cabinet for suitable 
protection. The enclosure shall not be accessible without tools. 
 

2.2

 

Installation 

The  installation  is  to  be  made  by  competent  personnel  and  in  accordance  with 
applicable  regulations.  Before  installation  please  check  that  the  transducer  has  the 
correct type and complies with the installation needs. The connection to the transducer 
is  done  through  the  terminals  that  are  designed  for  a  maximum  of  6  mm²  cable  in 
accordance with connection diagram. An external switch shall be used so that the unit 
can  be  deenergized  during  disassembly.  It  shall  be  appropriately  positioned,  easy  to 
reach  and  marked  as  a  switch  for  the  transducer.  The  measuring  circuits  from  the 
current  transformers  must  be  short-circuited  before  disconnection.  The  unit  must  be 
protected against possible overcurrent by automatic circuit breaker.  

2.3

 

Operation 

The transducer is intended for operation at an altitude not exceeding 2000m and in an 
environment that is not considered as wet location. 

2.4

 

 Warning! 

Connection must comply with current regulations for systems with rated voltage up to 
1000 V. 
 
Before  switching on or off and  if the housing is removed, all voltages to the  appliance 
must be switched off. 

2.5

 

Maintenance 

The  transducer  requires  no  maintenance.  Any  repairs  shall  be  performed  by  trained 
personnel or the appliance shall be returned to the supplier for repair. 
 
Function and safety are only guaranteed if the instructions in this manual are followed.
