Important: The PowerSource 660 is not suitable for use with certain products and loads. The continuous output wattage of this product is limited to 1440 watts total when supplying backup power from its batteries. This limit applies to the total of all items plugged into the product.
This output wattage is not sufficient to run products designed to produce large amounts of heat, including space heaters and pellet stove igniters.
PRECAUTIONS FOR USING RECHARGEABLE APPLIANCES
CAUTION: Equipment damage
When the PowerSource 660 is supplying backup power from its battery, its output is a non-sinusoidal modified sine wave, which is different from pure sine wave utility-supplied electricity. Certain types of load equipment may be damaged.
Most rechargeable battery-operated equipment uses a separate charger or transformer that is plugged into an AC receptacle and produces a low voltage charging output. Some chargers for rechargeable batteries can be damaged if connected to the PowerSource 660.
Do not use the following with the PowerSource 660:
- Small battery-operated appliances like flashlights, razors and night lights that can be plugged directly into an AC receptacle to recharge.
- Some chargers for battery packs used in hand power tools. These chargers display a warning label stating that dangerous voltages are present at the battery terminals.
NOTE:
If you are unsure about using your rechargeable appliance with the PowerSource 660, contact the equipment manufacturer to determine the rechargeable appliance’s compatibility with the modified sine wave (non-sinusoidal) AC wave form.
PRODUCTS WITH POTENTIAL PROBLEMS
Some products, including the types listed below, may be damaged if they are connected to the PowerSource 660:
- Speed controllers found in some fans, power tools, kitchen appliances, garage door openers, and other loads may be damaged.
- Metal halide arc (MHI) lights can be damaged.
