The orange LED will turn on. The unit will be latched in this shut down condition and
will require manual reset. To reset, switch OFF the unit using the 2-Postion Rocker
Switch “ON/OFF/EXT. Switch”, wait for 3 minutes and then switch ON the unit again.
Before switching ON, determine and remove the cause of overloading.
10.2 WARNING ALARM - LOW DC INPUT VOLTAGE
The voltage at the DC input terminals will be lower than the voltage at the battery
terminals due to voltage drop in the battery wires and connectors. The drop in the
voltage at the DC input terminals of the inverter could be due to lower battery
voltage or due to abnormally high drop in the battery wires if the wires are not thick
enough
.
If the voltage at the DC input terminals falls below 10.7V ± 0.1V for 12V
versions or 21.4V ± 0.2V for 24V versions, a buzzer alarm will be sounded. The green
LED will stay on. This warning buzzer alarm indicates that the battery is running low
and that the inverter will be shut down after sometime if the voltage at the in verter
terminals further drops to 10V ± 0.1V for 12V versions or 20V ± 0.2 V for 24V versions.
10.3 LOW DC INPUT VOLTAGE SHUT DOWN
If the voltage at the DC input terminals falls below 10V ± 0.1V for 12V versions or 20V
± 0.2V for 24V versions, the AC output is shut down. Buzzer alarm is sounded. The
orange LED will turn on.
The unit will reset automatically when the DC input voltage rises > 11.5V ± 0.3V for
12V versions and > 23V ± 0.5V for 24V versions.
10.4 HIGH DC INPUT VOLTAGE SHUTDOWN
If the voltage at the DC input terminals exceeds 16.5V for 12V versions or 33V for 24V
versions, the AC output voltage will be shut down temporarily. Buzzer alarm will be
sounded. The orange LED will turn on. The unit will be reset automatically when the
voltage drops down to < 16.5V for 12V versions and to < 33V for 24V versions.
