Front Panel Status Indicators:
Verify the status of the power supply from the LED display during normal operation.
All indicator LEDs are located on the front panel of the inverter module.
LINE (AC input /Mains)
o GREEN (nominal AC line voltage/normal operation)
o AMBER (qualifying AC line voltage)
o RED (AC input low or absent)
BATTERY
o GREEN (nominal battery voltage/normal operation)
o AMBER (high rate charge)
o RED (alarm: low voltage cutoff & sleep mode or batteries disconnected)
o RED, Blinking (alarm: batteries incapable of supporting standby operation)
SENSOR (Battery Temperature Sensor)
o GREEN (normal operation)
o Not Illuminated (disconnected or sensor fault)
TEST
o GREEN (test in progress initiated locally)
o AMBER (test initiated remotely)
o AMBER FLASH (data communication)
o RED (last test failed)
Press the TEST pushbutton switch, accessible through the front panel of the power
supply to initiate the test function locally. The power supply automatically tests the
batteries and internal circuitry for a factory-adjusted time of 5 minutes. Press the TEST
switch again to cancel the test at any time.
Backfeed Lockout Indication:
The power supply is equipped with a safety (anti-backfeed) circuit that prevents
inverter output from backfeeding the utility lines in case critical components within the
power supply fail. If the anti-backfeed circuit is activated, inverter operation is
automatically suspended and all front panel indicators, except the SENSOR indicator,
flash red. Removing both AC and DC inputs will reset the power supply and cancel
the backfeed lockout condition; however, corrective maintenance may be required to
repair the basic cause of the lockout condition.
Section 7: Power Supply Shutdown
If power supply shutdown becomes necessary at any time, observe the following
procedure:
