Operation
9.1 SWitcHinG tHe inVeRteR on/oFF
Before switching on the inverter, check that all the AC loads have been switched off. The
3-Position Rocker Switch marked oN/off/EXT. Switch (1, fig 6.1a) on the front panel of the
inverter is used to switch oN and switch off the inverter. This switch operates a low power
control circuitry, which in turn controls all the high power circuitry.
The unit can also be switched oN/off remotely as follows:
•
Through optional Remote Control Model RC-300 connected to Modular Jack RJ-50
(9, fig 6.1a). Read optional Remote Control Manual for RC-300 for details.
•
Using 2-wire or 1-wire External Switching Control. See details under heading "oN/off Con-
trol from Remote location using 2-Wire or 1-Wire External oN/off Control" on page 38.
!
cAUtion!
Please note that the oN/off switch is not switching the high power battery input
circuit. Parts of the DC side circuit will still be alive even when the switch is in the
off position. Hence, disconnect the DC and AC sides before working on any circuits
connected to the inverter.
When the inverter is switched oN, the Green LED marked "PoWER" (2, fig 6.1a) will be
lighted. This LED indicates that the input section of the inverter is operating normally. Under

for 3 minutes and then switch ON the unit again. Before switching ON, determine and
remove the cause of overloading.
SHORT CIRCUIT CONDITION: Short circuit condition will be detected when the AC
output voltage drops to 80VAC or lower over a period of around 1 to 1.5 sec. The AC
output voltage will be shut down thereafter.
R
The Green LED marked “POWER” (2, Fig 6.1a) 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 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.
ed LED marked “OVERLOAD” (3, Fig 6.1a) will turn ON, and buzzer alarm will sound.
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 page 30 “Connection From Batteries To the DC Input Side Sizing of Cables
and Fuses”
).
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 marked "
POWER
" (2, Fig 6.1a) and indication light on
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 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 Green
LED marked "
POWER
" (2, Fig 6.1a) will remain lighted. The Green indicati
on light on
the GfCI will be OFF.
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
" (2, Fig 6.1a) will rema
sounded. The Green LED marked "
POWER
i
n lighted. The unit
will be reset automatically when the voltage drops down to < 16.5V for 12V versions
and to < 33V for 24V versions.
To reset, switch OFF the unit using the 3-Postion Rocker Swith “ON/Off/EXT. Switch”, wait
