Figure 3B – Rear View M651 (shown with 6 position terminal block for External

Split-Core CTs – Current Input Option C)

3.1 Auxiliary Power

The M651 transducers are powered by connections to L1(+) and L2(-).  A Green LED
Power (PWR) indicator is provided on the rear panel to indicate that the unit is
powered ON. It is located on the right of the rear panel.
There is an option that allows the voltage across the Auxiliary Power input voltage
across terminals L1(+) and L2(-) to be monitored.  This monitoring option is only found
in 50 Series SCADA meters that have been manufactured with this monitoring option.
Refer to the order guide to verify whether the meter is made with this monitoring
option. ‘V Aux’ will appear on the display as a measurement for meters equipped with
this monitoring option.
