CLASS 500 ADVANCED KWH/DEMAND METER 11 62-0304—05 NOTE: One set of current sensors equates to th ree sensors, one per phase. The multiplier only appli es when extra sets of cur- rent sensors are installed on one Class 50 0 Meter . Therefore, if you are using on ly one set of three current sensors, the multiplier is not required.
CLASS 500 ADVANCED KWH/DEMAND METER 62-0304—0 5 12 MAINTENANCE The Class 500 Meter unit is shi pped in a calibrated an d fully fu nctionally tested condi tion. Sinc e the u nit is factory calibrat ed using proprietary firmware algorithms, no internal uni t adjustments ar e nece ssary .
CLASS 500 ADVANCED KWH/DEMAND METER 13 62-0304—05 Use the following procedure to re place the lithium battery cell. 1. Disconnect power from the Class 500 Meter at the unit external circuit breaker . 2. Remove the battery from its socket and place it on a non-conductive surface.
