4.2 Electric connections 

 
 

 

 

Power supply 

 

AC: L(L1), N(L2), P.E. 

 

DC: L(L1), N(L2), P.E. 

 

In the case of DC power supply it is not necessary to respect the polarity. 

Connect only one power source (AC or DC) at a time.

 

 

It is recommended to use pre-insulated female faston terminals 6,3x0,8 mm. 

In order to respect limits of EN61800-3 Category C1 for irradiated disturbs, it is necessary to add a ferrite on input phases L 
and N. The ferrite and cabling instructions are available on request. 

Recommended line cables stripping (without ferrite)
