       CHAPTER 1 – Electrical Wiring 

 

1.1.

 

 Electrical connections 

 

All Connections, except those to the CT core of the ElNet PFC 
Power Factor Controller are made via terminal connector plugs. 
Recommended max tightening torque for the connector screws is 
0.5 Nm. 
The CT cores of the ElNet PFC Power Factor Controller are 
located externally on the rear of the instrument and the lead from 
the leg of the external Current Transformer must pass through in 
the correct direction. 
 

 
 

NOTE!

!

 

Ensure all the connections to the leads of the current 
transformer wiring are secure and there is no mechanical 
strain on the wire. The cross section of the leads to the 
Current transformer must be compatible with the power of 
the current transformer. We recommend a power transformer 
with at least 3VA and the length of the wiring of the 
transformer should not exceed 5m.
