6.3 KWh Meter Hardware Functions

The Main circuit board is located inside the meter enclosure.

Fig. 14. Hardware Functions

IDR Jack 

8-pin RJ-45-used to connect kWh meter to the E-

Mon Energy automatic meter reading system.

Calibration Jack

Connector J11 is for factory calibration only, and is 

not a user accessible port. Silicon plug is not to be 

removed. 

Error LED 

When lit, indicates that the current sensor is 

backwards or on the incorrect phase.

Meter Pulse LED 

Blinks to show the meter load. Blink rate increases 

with load.

Power On LED 

When lit, indicates power to meter is on. 

Pulse Output  

Optically isolated output pulse for connection to 

BAS or peripheral equipment.
