OPERATION
appliance or equipment being operated will not signif- icantly decrease the power being generated by the inverter. For best operating results, the extension cord should be no more than 50 feet long.
•Check frequently to ensure that the input and out put connections are secure. Loose connections may damage the inverter, the power source, or may generate excessive heat.
•The following precautions apply to the 2000 series models only.
a). The AC receptacles are equipped with 15 amp cir- cuit breakers. Consequently, each of these outlets is rated for a maximum output of 1500 watts (110 volts x 15 amps).
To generate the maximum output, the 2000 series models should be connected to a power supply which has the capacity to produce up to 275 amps. The loads should be distributed between the two receptacles to ensure that each outlet is producing no more than its maximum 1500 watt output.
If more than one piece of equipment or appliance is to be operated at the same time, first turn on the inverter and then turn on each piece of equipment or appliance separately to enable the inverter to produce the required start up loads.

OPERATION
b). The 2000 series models are designed for direct wiring to an electrical distribution panel via the direct wire connection "cut out" on the front panel of the inverter.
This direct wire connection must be performed only by a licensed electrician. Failure to make this connection properly may result in severe injury.
Important Information on Battery Chargers
Using your inverter to recharge units designed to charge such portable equipment as power tools, flashlights, video cameras and laptop computers may cause damage to the inverter or the charging unit. Check with the appliance manufacturer for compatibility with sine wave inverters if you’re unsure.
Although we advise against it, if you attempt to recharge a charging unit, monitor the temperature of the charging unit for approximately 10 minutes. If the charging unit
becomes unusually warm, disconnect it from the inverter immediately.
The Power Source.
When the engine is off, most batteries will provide ample power supply to the inverter for one to two hours. The actual length of time is a function of several variables including the age and condition of the battery, the number of batteries and the power demand being placed on it by the equipment being operated with the inverter.
