4.5.4 Multiple-Load Monitoring

The Din-Mon™ kWh meter provides extreme flexibility by allowing additional sets of

current sensors to be used in parallel so multiple load locations can be monitored by

one meter. This feature allows totalized display readout from two or more load circuits.

NOTE: Paralleling of current sensors applies only to those designed for 0.333V

output (“V3”); 100mA output (“C1”) sensors must not be paralleled.

When paralleling current sensors, the following rules must be followed:

1. Current sensors must be installed in complete sets of three (or two with single

phase installations), with a maximum of three sensors installed in parallel per

phase.

2. All sensors used in parallel must be of the same type and amperage. rating. The

rating is determined by the current rating of the meter. For example, a 200-Amp

meter must use extra sets of 200-Amp sensors.

3. All locations being monitored must have the same power source. A 480 Volt

meter cannot monitor a 208 Volt load, nor can a meter monitor two 480 Volt

loads if they are from different originating power sources or from different trans-

formers.

4. Multiply the meter display readings by the number of sets of current sensors

installed. Example: Meter readings of 5 kWh with 2 sets of current sensors, the

actual usage is 10 kWh. (5 x 2=10).
