Red LED marked “OVERLOAD” (3, Fig 6.1) will turn ON and buzzer alarm will sound.
The Green LED marked “POWER” (2, Fig 6.1) will continue to be lighted. The unit will be
latched in this shut down condition and will require manual reset. To reset, switch OFF
the unit using the ON/OFF Switch (1, Fig 6.1), wait for 3 minutes and then switch ON the
unit again. Before switching ON, determine and remove the cause of short circuit.
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
(Please see Section 8.4.3 “Connection from Batteries to the DC Input Side – Sizing of
Cables and Fuses”). If the voltage at the DC input terminals drops to 42.0V ± 0.5V or
lower, a buzzer alarm will be sounded. The Green LED marked "POWER" (2, Fig 6.1) 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
40.0V ± 0.5V or lower.
10.3 LOW DC INPUT VOLTAGE SHUT DOWN
If the voltage at the DC input terminals drops to 40.0V ± 0.5V or lower, the AC output is
shut down. Buzzer alarm is sounded. The Green LED marked "POWER" (2, Fig 6.1) will
remain lighted.
The unit will reset automatically when the DC input voltage rises to 46.0V ± 0.5V or higher.
10.4 HIGH DC INPUT VOLTAGE SHUTDOWN
If the voltage at the DC input terminals rises to 64.0V or higher, for the AC output
voltage will be shut down temporarily. Buzzer alarm will be sounded. The Green LED
marked "POWER" (2, Fig 6.1) will remain lighted. The unit will be reset automatically
when the voltage drops down to < 64.0.
10.5 OVER-TEMPERATURE SHUT DOWN
In case of failure of the cooling fan or in the case of inadequate heat removal due to
higher ambient temperatures / insufficient air exchange, the temperature inside the unit
will increase. The temperature of a critical hot spot inside the inverter is monitored, and
at 90°C ± 5°C, the AC output of the inverter is shut down temporarily. Buzzer alarm will
be sounded. The Green LED marked "POWER" (2, Fig 6.1) will remain lighted. The Green
indication light on the GFCI will be OFF.
The unit will automatically reset after the hot spot has cooled down to 65°C ± 5°C.
