Installation of the RGM40 meter must be 
performed only by qualified personnel who  
follow standard safety precautions during all 
procedures. Those personnel should have 
appropriate training and experience with high 
voltage devices. Appropriate safety gloves, 
safety glasses and protective clothing are 
recommended.

During normal operation of the RGM40 meter, 
dangerous voltages flow through many parts of  
the unit, including: Terminals and any connected 
CTs (current transformers) and PTs (potential 
transformers), all I/O modules and their circuits.  
All primary and secondary circuits can, at times, 
produce lethal voltages and currents. Avoid  
contact with any current-carrying surfaces.

Do not use the meter or any I/O device for 
primary protection or in an energy-limiting 
capacity. The meter can only be used as 
secondary protection.

IMPORTANT! Refer to your meter’s user  
manual for additional safety warnings before 
performing installation, wiring or maintenance 
of your meter. 

1.  Slide top groove of meter 

onto the DIN rail.

2.  Press gently until the meter 

clicks into place.

3.  Use two screws to secure 

the meter to the DIN rail.
