Operational Analysis
UTILITY SOURCE AVAILABLE
Utility voltage is available to the transfer switch terminals N1/N2 and the transfer switch in the normal utility position.
Utility sensing voltage is delivered to the controller via wires N1/N2 from a transfer switch. This voltage is 240VAC sensing voltage
only for the controller. T1 is 120 VAC supply for power to the battery charger.
Battery output voltage is delivered to the controller via wire 13 when the battery is installed.
