OPERATING MODES
On-Line Operation
CB1, SW1, SW2 and the Battery CB are in the on position and SW3 is in the off position. The loads are supplied by the mains
through the inverter. The batteries are charged by the rectifier as necessary. The Inverter filters mains interruptions, disturbances
and provides a stable, interference-free supply to the load.
The summary alarm LED on the control panel is not illuminated in this mode. If a mains failure occurs while in On-Line operation,
the UPS switches to Battery Operation. The On Battery and Summary Alarm LEDs are illuminated. If an overload condition occurs
at the output, the UPS switches to By-pass operation, if available.
