 Connection diagram for current measurement using current transformers 

 

Snap the device onto the DIN rail. The terminals for the mains should be 
located at the top. 

 

If the device is operated with external current transformers, then connect 
according to Fig. 3.  
When connecting the cables to the screw terminals of the device, the neutral 
conductor must be connected to the device first. On removal, the neutral 
conductor must be disconnected from the device last. 

 

NOTE: A load must always be inserted between the output and the neutral 
conductor (>< symbol). The output and neutral conductor may not be 
connected without a load. 

 

The mains voltage infeed lines to the primary sides of the current transformers 
must be protected according to the primary rated current and the current 
rating of the cable with F1, F2, F3 fuses (max. 75 A). 

 

The secondary sides of the current transformers are connected in a single-
pole manner to the mains voltage using a cable to be protected with the rated 
current of the energy detector 2103 REG ES. The poles of the secondary 
sides of the current transformers are to be connected using the inputs E1, E2 
and E3 of the energy detector 2103 REG ES. The cable cross-section must be 
2.5 mm
