appliance requires less power to continue to operate. This is referred to as the “continuous load” in terms of
power requirements.
You will need to determine how much power your tool or appliance requires to start up and how much power it requires
for continuous running. Power consumption is rated either in wattages (watts) or in amperes (amps). Multiply: AMPS X
220 (AC voltage) = WATTS
This formula yields a close approximation of the continuous load of your appliances.
Multiply: WATTS x 2 = Starting Load
This formula yields a close approximation of the starting load of your appliances.
Most often the start-up load of the appliance or power tool determines whether the inverter has the capability to power it.
CAUTION
Know the wattage requirement of your appliances. Use only those appliances that do not
exceed the capacity of this unit.
The output waveform of this inverter is a MODIFIED SINE WAVE. It has a total harmonic distortion of 28% and maximum
single harmonic of 18%. If you choose to measure the AC output voltage, you must use a TRUE RMS VOLT METER such
as a Fluke 8060A, Fluke 87, Triplett 4200, Beckman 4410 or any “True RMS” multimeter. Using any other type of voltage
measuring device will result in an AC voltage reading of 20 to 30 volts lower than the rated value.
CAUTION
Do not use this Powerstation with equipment that can be damaged by the inverter's modified sine wave output (non-sinusoidal)
including (but not limited to) appliances with speed controllers (such as power tools). · Metal halide arc (MHI) lights can be
damaged.
NOTE: If you are unsure about powering any device with the inverter, contact the equipment manufacturer to
determine the appliance's compatibility with the modified sine wave (non-sinusoidal) AC waveform.
1.2 Operating instructions
Before using the inverter, ensure that the battery of your Powerstation is fully charged. Place the inverter power switch in
the on position. The digital display will come on to confirm that the AC outlet is powered. If the AC product you are
operating has a power switch, we recommend that it be put in the “OFF” position. Plug product into the AC outlet and
proceed to use according to the directions on the product. The Powerstation will operate most devices rated up to 400
watts. The AC Power supply is equipped with a low battery alarm and an automatic shutdown feature to protect the unit if
the battery power drops below the safe recharging level. If the alarm sounds while you are operating an AC product, shut
off the device immediately and discontinue use until the Powerstation battery can be recharged. Switch inverter “OFF”
and disconnect the AC product. Recharge battery as soon as possible and before further use. If you ignore the warning
alarm, the power supply will automatically shut down and your AC product will instantly lose power. The AC power supply
function is also protected against overloads and overheating. If either of these conditions should occur, the power inverter
will shut down automatically.
