LEDs and Audio Alarms
Green – Power On
Red Light and/or Audio Alarm
Current Overload – Red LED glows for a short time and
inverter shuts down. Current load too high for inverter.
Reduce current demand.
Voltage Overload – Red LED glows and inverter shuts
down. Voltage range of 15.5V ± 0.5V DC too high for
inverter. Voltage exceeding 16 volts may damage the
inverter. Reduce voltage range to 12 volts to 14 volts.
Voltage Shortage – Alarm sounds indicating voltage is
getting low (10.5V ± 0.3V DC). Inverter shuts down and
red light glows when voltage falls below 10.0V ± 0.3V DC.
Inverter needs voltage source between 12 volts and 14
volts.
Temperature Overload – Red LED glows for a short time
and inverter shuts down. Provide ample ventilation for
inverter to restart.
Analogic Output Power Display - shows AC continuous
power consumed. Five lights indicate half of the continu-
ous output power and ten lights indicate full continuous
