INTRODUCTION:
This inverter can operate most AC appliances such as camcorders, computers, fax machines, TVs, and
power tools from the 12V DC current from your vehicles battery. This fully portable unit gives you a
standard AC outlet anywhere your vehicle is located.
FEATURES:
▪ Low Battery Automatic Shutdown
▪ Overload and Short Circuit Protection
▪ Reverse Polarity Protection
▪ Compact Size, Light Weight, and High Efficiency
▪ High Surge Current Capability to Start TVs, Motors and Other Inductive Loads
▪ Thermal Protection
▪ Built-in Cooling Fans
▪ Soft Start Technology

INSTALLATION AND OPERATION:
1. Using the included cables, directly connect the inverters (-) and (+) terminals to your
automotive batteries respective (-) and (+) terminals, (See Figure 1 below). The cables
should be bolted to the battery clamps for a solid connection (do not use jumper cables for
installation). We recommend using an ANL inline fuse or circuit breaker (not included).
The ANL fuse or breaker should be as close to the battery as possible, installed on the
positive (+) cable. Please refer to the specifications table on page 1 for recommended
wire sizes and fuse/breaker sizing. NOTE: There will be a spark between the cable from
the negative terminal of the inverter when it is first connected to the negative terminal of the
battery

2. With the inverter switched “OFF” plug the AC appliance into the inverter.
3. Turn the inverter on.
OPERATION NOTES:
1. Low Battery Alarm: the inverter sounds an audible alarm and turns itself off if the source
battery becomes too low.
2. EQUIPMENT LOAD: The unit has a built-in overload protection circuit. If the inverter is
overloaded the inverter will turn off. In order to resume output the load will need to be removed
and the inverter will need to be turned off then back on. Inductive loads may draw 3-5X or more
than their normal current in order to start and while under a heavy load.
3. BATTERY POLARITY: The black (-) negative post on the inverter MUST be hooked to the negative
(-) terminal of the battery.
The red (+) post on the inverter MUST be hooked to the positive (+) terminal of the battery.
4. DISPERSION OF HEAT: During normal operation the inverter will get warm. The amount of heat
generated will vary with the power draw of the equipment being operated. The inverter MUST be
installed in a manner that allows air to circulate freely around the inverter. The sound created by
the fan and the air being moved through the inverter to cool it is normal.
5. USE OF CAR BATTERY: To prevent a vehicle battery from discharging below the voltage required
to start the vehicle engine, we recommend that the operator start the vehicle before battery voltage
is reduced to 11 volts to recharge the battery system. The unit may be used while the engine is
running or turned off. However, do not start a vehicle’s engine while the inverter is in use.
6. LOW VOLTAGE AND OVERVOLTAGE CONDITIONS: When input voltage decreases to ~10.5V,
the output will turn off. When the input voltage increases to ~15.5V, the output will turn off.

7. EXTENSION CORDS: The use of extension cords from the AC outlet will not significantly decrease
the power supplied by the unit. However, for the best operating results, an extension cord of less
than 60 feet is recommended. Use 3 prong extension cords. Use exterior extension cords.
The Inverter model # 53300 is equipped with a special auxiliary socket for an optional
extended wired ON/OFF remote switch (sold separately).
