DEVICE INSTALLATION 

4.2.1 

Mechanical Installation  

Mechanically, the device is intended to be mounted attached  to the front door of the cabinet. The fitting 
hole must be according to DIN 43 700, (dimensions 138

+1

x138

+1

mm). 

4.2.2 

Connections  

Before connecting the supply to the device check the following items: 

 

The installation  and maintenance  of the device must be carried  out by specialised and dully 
trained staff, according to National Electric Codes and Rules and International Standards 

All the connections must be at the inner part of a protection cabinet. 

Notice that when the device is connected to supply, the 

voltage at certain terminals can be 

hazardous  and  cause  electric  shock 

in  case  of  contact.  Opening  the  electrical  cabinet  or 

removing  certain  covers  can  compromise  the  user  safety  and  should  only  be  done  by 
qualified and authorized staff. 

The 

REG-6S-100  and REG-12S-100

 devices are used together  with capacitor  banks, which 

can remain charged after supply disconnection. In order to avoid shock hazard, wait during 5 
minutes after supply disconnection before any manipulation inside the equipment cabinet.

 

REG-6S-100 and REG-12S-100

 

devices require current sensing of the installation. A current transformer 

(CT) must be installed externally to perform this function.  Usually the current ratio of the CT is 

I

n

 / 5  A

, 

where 

In

 must be at least 1,5 times the maximum expected load current. 

The CT must be installed at the incoming supply line (point of coupling of the user), so that it measures 
the total current of all the loads, including also the compensation capacitor bank (see fig. 4.1) 

The CT should be installed preferably in phase L1, while the voltage measuring terminals of 

REG-6S-100 

and REG-12S-100

 

should  be connected  to phases L2 and L3 (see schematic

s in figs. 4.2 and 4.3). It’s 

important  to  respect  the  connection  senses  of  P1-P2  and  S1-S2  shown  in  the  above  mentioned  figs, 
otherwise  the  phase  difference  will  have  to  be  corrected  by  adjusting  the  device  according  to  set-up 
procedure indicated in paragraph 5.17.
