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.
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 re c h a rge units designed to charge such
p o rtable 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 re c h a rg e
a charging unit, monitor the temperature of the charg i n g
unit for approximately 10 minutes. If the charging unit
becomes unusually warm, disconnect it from the invert e r
i m m e d i a t e l y.
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 invert e r.
