WARNING
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 ins an ly burn he inver er.
Although this inverter has a high input OVE VOLTAGE SHUT DOWN at 15V, input voltages higher
than 15V will cause permanen 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.
nDo 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.
nDo not connect to 24V battery (for 12V inverters).
nEnsure that the voltage of the battery charger does not exceed 15V in any condition.
Do no reverse he polari y of he inpu connec ions. This will
permanen ly damage he inver er.

QUICK HOOK-UP AND TESTING
If you would like o quickly hook up he inver er and check i s
performance before going ahead wi h your ins alla ion, please follow
hese guidelines:
1. Unpack and inspect the inverter, check to see that the power switch is in the OFF position.
2. Connect the cables to the power input terminals on the rear panel of the inverter. The red
terminal is posi ive (+) and the black terminal is nega ive (-). Connect the cables
into the terminals and tighten the screws to clamp the wires securely.
3. Connect the cable from the negative terminal of the inverter to the negative terminal of the
power source. Make a secure connection.
CAUTION ! Loosely igh ened connec ors may cause overhea ed wires
and mel ed insula ion.
4. Before proceeding further carefully check that the cable you have just connected, connects
from the negative terminal of the inverter to the negative output terminal of the power source.
CAUTION ! Reverse polari y connec ion will blow a fuse in he inver er
and may cause permanen damage o he inver er. Damage caused by
reverse polari y connec ion is no covered by warran y.
5. Connect the cable from the positive terminal of the inverter to the positive terminal of the
power source. Make a secure connection.
WARNING ! You may observe a spark when you make his connec ion
since curren may flow o charge he capaci ors in he inver er. Do
no make his connec ion in he presence of flammable fumes,
explosion or fire may resul .
6. Set the inverter switch to the ON position, the internal alarm may sound momentarily. This
is normal. Plug the test load on. If you plan to measure the output voltage, you must use a
true MS Voltage Meter such as a Fluke 8060A or Triplett 4200. A standard averaging volt
meter will not provide an accurate reading.

INSTALLATION
1. Where o ins all
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. Ven ila ed - 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
wire available. See chart below :

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.
Cau ion!

OPERATION
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.
1. Con rols and indica ors
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 con rol and over emp. alarm and pro ec ion
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. (No e ha
he fan will no cu in on no load or on ligh loads as he emp 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 indica or
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.
Opera ing limi s: Inpu vol age pro ec ion and alarm
The power inverter will operate from input voltage ranging from 10V-15V (12V version) or 20V-
30V (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 over-
discharged.
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.
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).
TROUBLESHOOTING
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.
nMake 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.
nDo not operate high power loads with the power inverter while watching
television.
nMake 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.
nMove the television as far away from the power inverter as possible.
nKeep 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.
