shown in the diagram below. Each indicator illuminates to specify the
status of the UPS (see Troubleshooting section for details).
Utility/Battery Indicator (Green)
The Utility/Battery Indicator illuminates when the UPS is operating
in Normal mode, supplying power to connected loads. The Utility/Bat-
tery Indicator flashes when the UPS is operating in Battery mode.
Site Wiring Fault Indicator (Amber)
The Site Wiring Fault Indicator flashes amber when the UPS detects
a line-neutral reversal or a poor neutral-ground bonding.
Fault Indicator (Red)
The Fault Indicator illuminates when the UPS detects an internal
fault. It flashes if the UPS detects an overload condition.
