4.2.6. Step 5: Connect Power
Before making any connections, ensure that the power switch in
OFF position.
Identify an appropriate AC power source
The AC power source must not be derived from the energy system itself without an ability to
maintain (or turn on) the supply when the energy system is powered off.
An external UPS can be used between the energy system-derived AC source and the supply
providing power to the Battery Control Panel when an external AC power source is not available.
Connect the power cable to the 'Power In'
The 'Power In' interface is an IEC 320-C14 connector requiring external 120/240 V AC power. It is
compatible with locally-sourced AC line cords and features: line filtering, a built-in 4 A breaker,
and an illumination LED to indicate power presence.
4.2.7. Note on Communication ('COM') interface
The Communication ('COM') interface is a D-Sub connector that should be treated as a NC (no-
connect).
