3 Electrical Installation 

3.1 Power Supply 

The power source can be dedicated-fused, or from a monitored 
voltage if it is within the transducer power supply range.  
AC power supply: line to terminal 12; neutral to terminal 10.  
DC power supply: positive to terminal 12; negative to terminal 10.

3-1 Locations of Terminals: Front View 

NOTE: Power source connection requires use of the suppression core 

provided with the instrument. 

IMPORTANT: It is recommended to solder the wire ends 

before attaching them to the connectors. 

3.2 Current Inputs 

To ensure accurate readings, the input current should not exceed 
1.2A RMS and 1.76A amplitude for the 1A CT secondary, or 6A 
RMS and 8.8A amplitude for the 5A CT secondary.
