Protections
The inverter has been provided with protections detailed below:
overload / Short circuit Shut Down
Theinvertercanprovideahigherthannormalinstantaneouspower(<1second)limited
tothesurgepowerratingoftheinverter.Also,theinvertercanprovidecontinuous
power limited to the continuous power rating of the inverter. If there is an overload
beyondthesespecifiedlimits,theACoutputoftheunitwillbeshutdownpermanently.
REDLEDmarked“oVERLoAD”(3)willbelightedandGREENLEDmarked“PoWER”(2)
will be switched off. The unit will be latched in this shutdown condition and will require
manualreset.Toreset,switchoff the power oN/offswitch,waitfor3minutesandthen
switch oNagain.Beforeswitchingonagain,removethecauseoftheshutdown.
Warning Alarm - Low Dc input Voltage
ThevoltageattheDCinputterminals(8,9)willbelowerthanthevoltageatthebat-
tery terminals due to voltage drop in the battery wires and connectors. The drop in the

(Please read “Section 8, Installation; DC SIDE CONNECTIONS; Connection From the Bat-
teries To the DC Input Side of The Unit – Wire and External Fuse Sizes”).Ifthevoltage
attheDCinputterminalsfallsbelow10.7Vfor12Vversionsor21.4Vfor24Vversions,
a buzzer alarm will be sounded. The GREENLEDmarked“PoWER”(2)willcontinueto
lightedandtheACoutputvoltagewouldcontinuetobeavailable.Thiswarningbuzzer
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

DCinputvoltagerises>11.5Vfor12Vversionsand>23Vfor24Vversions.
High Dc input Voltage Shutdown

over-temperature Shut Down
In case of failure of the cooling fan or in the case of inadequate heat removal due to
higherambienttemperatures/insufficientairexchange,thetemperatureinsidetheunit
will increase. The temperature of a critical hot spot inside the inverter is monitored and
at95°C,theACoutputoftheinverterisshutdowntemporarily.TheREDLEDmarked
