WARNING: Heat Hazard The inverter housing may become uncomfortably warm, reaching 60°C (140°F) under extended high power operation. Ensure that at least 5 cm (2 inches) of air surround the inverter. During operation, keep it away from materials that may be affected by high temperatures. WARNING: Explosion Hazard Do not use the inverter in the presence of fl...

CAUTION: Output Non-Sinusoidal Some chargers for small nickel-cadmium batteries can be damaged if connected to the inverter. Do not use the inverter with the following appliances: • Small battery-operated appliances like rechargeable fl ashlights, some rechargeable shavers, and night lights that are plugged directly into an AC receptacle to recharge.
Additional Safety Guidelines • Do not insert foreign objects in the inverter outlets or other openings. • Never connect the inverter to power utility AC distribution wiring. • Do not use the inverter in temperatures over 40°C (104°F). • Do not expose the inverter to water, rain, snow, or spray.
3. Safety Guidelines These advanced safety features are built into the Fusion 300W Inverter: • Electronic overload protection with automatic shutdown • Built-in internal backup DC fuse • Low battery voltage warning followed by automatic shutdown • High-input voltage protection with automatic shutdown •...
4. Installation Guidelines Selecting a suitable location For safe and optimum performance, install the inverter in a location that is: Do not expose to water drip or spray. Cool Operate only in ambient temperatures between 0°C (32°F) and 40°C (104°F). Keep away from furnace heating vents or other heat producing equipment.
5. Using the Inverter The inverter is capable of continuously powering most 120 V AC products that use 240 W or less. Its AC output waveform, called “modifi ed-sine wave,” is designed to function similarly to the sine wave shape of utility power.
Using the DC cable with cigarette lighter plug Due to the limitations of 12 V outlets in vehicles or boats, the inverter should only be used to supply AC power to products that require 100 W (about 0.8 A) or less. If your application requires more than 100 W (but less than 240 W continuous) or has a high start- up surge, see “Using the DC cable clips.”...

3. Insert the plug of this cable into the 12 V outlet and switch the unit ON. 4. When the power inverter is not in use, unplug it from the 12 V outlet to prevent slight discharge of the battery.
Using the DC cable clips By directly connecting the power inverter to a 12 V battery using the DC cable clips, you can operate products with power requirements for 300 W. 1. Follow steps 1 and 2 above (Using the DC Cable with cigarette lighter plug) to attach the ring type connectors.

• Two AC outlets are provided on one end of the inverter. Any combination of 120 V AC products with a total continuous power consumption of 240 W or less may be plugged in. • The ON/OFF switch enables output AC power at the AC outlet(s) when switched ON.
7. Inverter Operation 1. When properly connected to a 12 V outlet or battery, turning the inverter switch ON, will illuminate the green POWER light, and deliver AC power to the outlet(s). 2. Plug the AC product(s) you wish to operate into the AC outlet(s) and switch them on, one at a time.

Important: Vehicle batteries are designed to provide brief periods of very high current needed for engine starting. They are not intended for constant deep discharge. Regularly operating the inverter from a vehicle battery until the low voltage alarm sounds will shorten the life of the battery. Consider connecting the power inverter to a separate deep-cycle battery if you will be frequently running electrical products for extended periods of time.
CAUTION: Although the inverter incorporates protection against over-voltage, it may still be damaged if the input voltage exceeds 16 V. 8. The cooling fan is designed to operate only when output power is greater than approximately 100W. When the inverter is turned on, the fan may operate momentarily.
When using a vehicle battery as a power source, it is strongly recommended to start the vehicle every hour or two to recharge the battery before its capacity drops too low. The inverter can operate while the engine is running, but the normal voltage drop that occurs during starting of the engine may trigger the inverter’s low voltage shutdown feature.

Buzzing sound in audio systems and radios Some inexpensive stereo systems, “boom boxes,” and AM-FM radios have inadequate internal power supply fi ltering and “buzz” slightly when powered by the inverter. Generally, the only solution is an audio product with a higher quality fi lter. Television interference The inverter is shielded to minimize its interference with TV signals.
