OWNER'S MANUAL
Please read this manual before operating your inverter.
WARNING
Staple a copy of your bill of sale here. You will need to present your bill
of sale to make any required warranty claim.
PLEASE TAKE THE FOLLOWING PRECAUTIONS. FAILURE TO ABIDE BY
THESE REQUIREMENTS WILL VOID THE WARRANTY.
Never parallel the 115V AC output of the inverter with the output from a generator or the electric
mains. This will instantly burn the inverter.
Although this inverter has a high input OVER VOLTAGE SHUT DOWN at 15V, input voltages higher
than 15V will cause permanent damage. Ensure the following when the battery is being
charged simultaneously (the output voltage of the charging device will be fed to the inverter):
n
Ensure that the charging voltage of the alternator has not been set about 15V.
n
Do not use an unregulated solar panel, it's voltage can reach up to 18V on a very cold day.
When using regulated solar panel, it's voltage should not be set beyond 15V.
n
Do not connect to 24V battery (for 12V inverters).
n
Ensure that the voltage of the battery charger does not exceed 15V in any condition.
Do not reverse the polarity of the input connections. This will
permanently damage the inverter.

& SYMPTOMS
The power inverter should be installed in a location that meets the following requirements:
a. Dry -Do not allow water to drip or splash in the inverter.
b. Cool - Ambient air temperature should be between 0o C and 40o C, the cooler the better.
c. Ventilated - Allow at least one inch of clearance around the inverter for air flow. Ensure the
ventilation openings on the rear and bottom of the unit are not obstructed.
d. Safe-Do not install the inverter in the same compartment as batteries or in any
compartment capable of storing flammable liquids such as gasoline.
2. Cables
DC to AC inverters convert high amperage/low voltage DC power to low amperage/high voltage AC
power. To operate properly connect inverter DC input terminals direct to battery with heaviest

3. Grounding
The power inverter has a lug on the rear panel “chassis ground”. This is to connect the chassis of the
power inverter to the ground. The ground terminals in the AC outlets on the front panel of the inverter
are also connected to the ground lug. The chassis ground lug must be connected to a grounding point,
which will vary depending on where the power inverter is installed. In a vehicle, connect the chassis
ground to the chassis of the vehicle. In a boat, connect to the boat’s grounding systems. In a fixed
location, connect the chassis ground lug to earth. The neutral (common) conductor of the power
inverter AC output circuit is connected to the chassis ground. Therefore, when the chassis is connected
to ground, the neutral conductor will also be grounded. This conforms to national electrical code
requirements that separately derived AC sources (such as inverters and generators) have their neutral
tied to ground in the same way that the neutral conductor from the utility line is tied to ground at the
AC breaker panel.
Caution!
Do not install the power inverter in a positive ground DC system. A positive
ground DC system has the positive terminal of the battery connected to the
chassis of the vehicle or to the grounding point.
Warning!
Internal fuse is open.
Have a qualified
technician check
and replace fuse.
Reverse DC polarity.
Have a qualified
service technician
check and replace fuse.
High input voltage
(>15V).
Make sure that the inverter
is connected to 12V battery.
Check regulation of charging
system.
Do not operate the power inverter without connecting it to ground. Electrical
shock hazard may result.
OBSERVE CORRECT POL ARITY

OPERATION
The power inverter will shut down and also produce an audible alarm if the input voltage exceeds
15V (12V version) or 30V (24V version). This protects the inverter from excessive input voltage.
To operate the power inverter, turn it on using the ON/OFF switch on the front panel. The power
inverter is now ready to deliver AC power to your loads. If you are operating several loads from the
power inverter, turn them on separately after the inverter has been turned on. This will ensure
that the power inverter does not have to deliver the starting currents for all the loads at once.
Although the power inverter incorporates protection against over-voltage, it may still be damaged
if the input voltage is allowed to exceed 15V (12V version) or 30V (24V version).
1. Controls and indicators
TROUBLESHOOTING
The ON/OFF switch turns the control circuit in the power inverter on and off. It does not
disconnect power from the power inverter.
When the switch is in the OFF position, the power inverter draws no current from the
battery. When the switch is in the ON position but with no load the power inverter draws less
than 400mA (12V version) or 230mA (24V version) from the battery.
2. Fan control and over temp. alarm and protection
This unit is cooled by a temp. controlled fan and is provided with over temp. alarm and
protection circuitry.
Temperature sensing is done from the surface of the Power Transformer T2 located inside the
unit. When it's temp reaches more than 40oC, the cooling fan is switched on. (Note that
the fan will not cut in on no load or on light loads as the temp of T2
will be below 40oC). In case the cooling fan fails or there is overload or the ambient
temp. is very high, the cooling will not be adequate and the temp. of T2 will start rising. At
around 57oC, an audible alarm will be sounded and at the same time, the power output of the
inverter will be shut down. Once T2 cools down to around 47oC, the unit will be reset
automatically.
3. Over-load indicator
1. Common problems
Television interference: Operation of the power inverter can interfere with television
reception on some channels. If this situation occurs, the following steps may help to alleviate
the problem.
n
Make sure that the chassis ground lug on the back of the power inverter
is solidly connected to the ground system of your vehicle, boat or home.
n
Do not operate high power loads with the power inverter while watching
television.
n
Make sure that the antenna feeding your television provides an
adequate (Snow- Free) signal and that you are using good quality
cable between the antenna and the television.
n
Move the television as far away from the power inverter as possible.
n
Keep the cables between the battery and the power inverter as short
as possible and twist them together with about 2 to 3 twists per foot.
This minimizes radiated interference from the cables.
The overload indicator indicates that the power inverter has shut itself down because its
output circuit has been short circuited or drastically overloaded. Switch the ON/OFF switch
to OFF, correct the fault condition, and then switch the ON/OFF switch back to ON.
Operating limits: Input voltage protection and alarm
The power inverter will operate from input voltage ranging from 10V-15V (12V version) or 20V30V (24V version). If the voltage drops below 10.7V (12V version) or 21.5V (24V version) an
audible low battery warning will sound. The power inverter will shut down if the input voltage
drops below 10V (12V version) or 20V (24V version). This protects your battery from being overdischarged.
