Indicators
AC INPUT.
Three green LEDs that indicate the presence of line voltage at the AC input. The
indicators turn on when the line voltage is greater than 90V (phase voltage greater than 52V).
ON BATT.
An amber LED that indicates the loss of AC input and operation from battery
power.
BATT.
A three-color LED that indicates the condition of the battery. The LED is green under
normal operating conditions, amber when the battery is discharging or has low capacity while
charging, and red when the battery capacity is low and impending inverter shutdown is
approached.
LOAD.
A three-color LED that indicates the amount of output load. The LED is green when the
load is less than 80% of maximum output, amber when the load is within 80% to 105%, and red
when the load exceeds 105% (indicating the inverter will shut down if the load is maintained).
TEMP.
A two-color LED that indicates temperature condition within the GUPS. The LED is
green under normal operating conditions, and red when an over-temperature shutdown occurs.
