AC LINE (green lamp)
Lights green when normal ac input is being
supplied to the UPS Unit.
INVERTER (green lamp)
Lights green when the UPS unit is operating in
the run mode and the output is normal.
Fault (red lamp)
Lights red when the UPS unit has tripped in the
fault mode.
OUTPUT/BATTERY (green/red lamp level
meter) The UPS unit's level meter consists of six
green and two red LED lamps.
INPUT/RECPT1/RECPT2/RECPT3
Directs to the unit's input breaker and its
respective set of receptacles.
Explanation
When output current is between 30% and 100%, the
green lamps light in 15% increments (from bottom to
top) to indicate relative output value (This sample
display shows a value level of approximately 45% to
60% of available output current).
All green lamps light and one or two red lamps flash
once per second. Remove overload as quickly as
possible to prevent fault (fault timeouts vary
depending on overload condition).
During battery backup all green and all red lamps flash
once per second. As the batteries discharge, the green
lamps extinguish from bottom to top to indicate
remaining battery capacity (This sample display shows
a value level of approximately 55% to 70% of available
battery capacity).
All green lamps are off and one or two red lamps
continue to flash.
