seCtIOn 10 | Protections
The inverter has been provided with protections detailed below:
overload / Short circuit Shut Down
The inverter can provide a higher than normal instantaneous power (< 1 second) limited
to the surge power rating of the inverter. Also, the inverter can provide continuous
power limited to the continuous power rating of the inverter. If there is an overload
beyond these specified limits, the AC output of the unit will be shut down permanently.
RED LED marked "overload" will turn oN, the GREEN indication on the GfCI will be
off and buzzer alarm will sound. The GREEN "Power oN" LED (2) will continue to be
lighted. The unit will be latched in this shutdown condition and will require manual
reset. To reset, switch off the power oN/off switch, wait for 3 minutes and then switch
oN again. before switching oN again, remove the cause of the shutdown.
Warning Alarm - Low Dc input Voltage
The voltage at the DC input terminals will be lower than the voltage at the battery ter-
minals 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 (Please
see page 31 "Connection From the Batteries To the DC Input Side of The Unit – Wire and
External Fuse Sizes"). If the voltage at the DC input terminals falls below 10.7V for 12V
versions or 21.4V for 24V versions, a buzzer alarm will be sounded. The GREEN "Power
oN" LED (2) and indication light on the GfCI will continue to be lighted and the AC
output voltage would continue to be available. 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 inverter terminals further drops to 10 V for 12 V versions or 20V for 24V
versions.
Low Dc input Voltage Shut Down
If the voltage at the DC input terminals falls below 10V for 12V versions or 20V for 24V
versions, the AC output is shut down. Buzzer alarm is sounded. The GREEN "Power oN"
LED (2) will remain lighted. The GREEN indication light on the GfCI will be off.
The unit will reset automatically when the DC input voltage rises > 11.5V for 12V ver-
sions and > 23V for 24V versions
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 inverter will be shut down temporarily. Buzzer alarm will be sounded.
The GREEN "Power oN" LED (2) will remain lighted. The GREEN indicator light on the
GfCI will be off. The unit will be reset automatically when the voltage drops down to <
16.5V for 12V versions and to < 33V for 24V versions.
