VOLTAGE MAY BE PRESENT. QUALIFIED PERSONNEL ONLY.
i These diagrams show the wiring confi guration for the Service Types available in the
Service drop-down list under "Meter Setup; Service " in ViewPoint HD Software.
The PowerScout HD Meter is internally powered through
i
the voltage between L1 and L2. For Single Phase
installations, where no L2 exists, connect a jumper from N
to L2. This connection provides power to the meter while
maintaining Neutral as the metering voltage reference.
The PowerScout HD Meter uses the Neutral terminal as a voltage reference. For
i
systems without a neutral conductor, connect a wire from the N terminal to ground.
