INTRODUCTION
To get the most out of your power inverter, proper installation is critical. Please read the installation and
operating instructions in this manual carefully before installing and using your power inverter. Pay special
attention to the CAUTION: statements in this manual. CAUTION: statements identify conditions or practices
which could result in damage to your power inverter or to other Equipment.
The power source must provide between 11(20) and 15(30) volts DC and must be able to supply sufficient current to
operate the load. As a rough guide line, divide the power consumption of the load (in watts) by 10(20) to obtain the
current (in amperes) in the power source must deliver.
Example: Load is rated at 300 watts. Power source must be able to deliver: 300 divided by 10=30 amperes.
CAUTION: Rechargeable batteries and devices with rechargeable batteries may not be suitable for use with the power
inverter. The rechargeable batteries, recharging transformer and/or the power inverter may be damaged when trying to
recharge devices of 24 volts and higher. The power inverter will not operate from a 6 volt battery.Refer to the
manufacturers specifications when using these devices.
PLACEMENT OF THE INVERTER
For best operating results, the inverter should be placed on a flat surface, such as the floor or seat of the vehicle. The
inverter should only be used in locations that meet the following requirements:
DRY — Keep away from water. Do not allow water to drip or splash on power inverter.
COOL — Ambient air temperature should be between 50 degrees and 80 degrees F. Do not place the inverter on or near a
heating vent or any piece of equipment which is generating heat above room temperature. If avoidable, do not place the
inverter in direct sunlight.
VENTILATED — Allow at least one inch of clearance around the power inverter for air flow. Do not place anything on
or over the inverter during operation.
Make sure that the air is allowed to circulate freely around the unit.
SAFETY — Do not use the power inverter near flammable materials or in any location which
may accumulate flammable fumes or gases, such as the battery compartment of your car,
truck, RV, or boat. This product is not suitable for use while traveling using battery clamps.
The length of the wire cables and battery clamps are not designed for this operation. If you wish to
operate the inverter while moving, the power inverter May be permanently mounted and wired.
CONNECTING TO THE POWER SOURCE
Your power inverter does not come equipped with battery cables which must be purchased
separately. The proper gauge of the battery cables can only be properly determined when
Calculating the length of the cables from the inverter to the battery. These cables may be
purchased from any automotive, marine or home center. (See Fig. 1 and Fig. 2)
CAUTION: DO NOT USE WITH POSITIVE GROUND

connect the chassis ground lug to the vehicle's chassis. In a boat connect to the grouding
system of the boat. In a fixed location connect to the ground.
OPERATING TIPS
RATED VERSUS ACTUALUSE OF EQUIPMENT
Most electrical tools, appliances and audio/video equipment have a label indicating power
consumption in amps or watts. Add up the power consumptionin those items you will be
using simultaneously, keeping total below max power of inverter. If the power consumption
i s ra t ed i n am ps , mu l t ip l y by t h e A C v o lt s (110/220/230/240) to determine the
wattage. For example, a television rated at 0.9 amps will use 99 watts, well within the limits
of what the power inverter can handle on a continuous basis. For more information
regarding the typical wattage draws of many appliances, please refer to the table on the back of this
manual.

Resistive loads, such as incandescent lights, are the easiest for the inverter to drive, though
larger resistive loads, such as electric stoves or heaters, require more power than the power
inverter can deliver continuouly. Inductive loads, such as TV's and stereos (any device with a
coil or a transformer in it) require more current to operate than a resistive load of the same power
rating. Induction motors (motors without brushes), as well as some televisions, may require 2
to 6 times their power rating to start up. This condition may require repeated "ON/OFF,
ON/OFF" several times switching of the power switch on your power inverter in order to get
them started. The most demanding are those that start under load, i.e. compressors and
pumps. Since motor and t e l evi s i o n ch a ract e rist i c s var y wi d ely, onl y
experimentation will determine if a specific load can be started and how long it can be run.
There are no standards for "surge power" partly because it can not be simply
represented by a simple of single sample number. Though the 300w power inverter can provide
power up to 600 watts for a short period, experimentation is the only method of determining
whether it can handle the surges generated by a particular load.
IMPORTANT NOTE: The power inverter will not operate most appliance designed to produce
heat, such as hair dryers, coffee makers, irons, heaters, and toasters. The current use of most
of these exceeds rated power watts, far beyond the capacity of this unit. The inverter may be
used either while engine is running or turned off. However, the inverter may not operate while the
engine is starting, since the battery voltage can drop substantially during cranking.
The power inverter draws less than 1.3 ampere from the battery when it is not supplying
power to the load. In most cases, the power inverter may be left connected to the battery
when it is not in use, since it draws so little current. If the vehicle will not be used for several
days, disconnect the power inverter from the battery.
LOW BATTERY ALARM
An alarm will sound when the voltage of the battery drops to 10.5volts. This indicates that the
battery requires recharging. The user should stop operations at this time, since the power
inverter will shut down automatically when battery voltage drops to 10.0 volts.
If the low battery alarm sounds when the battery is fully charged, follow the steps for correcting
the lack of output power in the Trouble Shooting Guide. The alarm will sound when the
inverter is overloaded, or if there is an excessive voltage drop between the battery and the
inverter.
NOTE: The alarm may sound momentarily when the unit is being connected to, or
disconnected from, the power source. This is normal and does not indicate any problem.

INDICATORS AND CONTROLS
BATTERY
OPERATING
TIME
The typical
vehicle battery
has a minimum
operating time of
1 to 2 hours,
depending on the
current use of
the load being
driven. We
recommend that
the opeator start
the vehicle
every hour to
recharge the
battery system. This will prevent unexpected shut downs of equipment and will ensure that
there is always sufficient battery capacity to start the engine.
Your power inverter circuitry constantly monitors the following hazardous conditions:
Low Battery Voltage — This condition is not harmful to the inverter, but could damage the
power source. An audible alarm is sounded when input voltage drops to 10.5 volts. The inverter
shuts down when input voltage drops to 10.0 volts. When the condition is corrected (i.e.
alternator charges battery). The unit may be restarted.
Short Circuit — Reverse polarity or short circuit condition of the load will usually
result in opening of the short circuit protecting.
High Temperature — When the temperature of the internal heat sinks reaches 150 degrees F, the
solid — state temperature sensor located in the power inverter will automatically shut down
the unit. Once it is allowed to cool, it may be restarted.
