Using the Inverter

5.3

It is important to know the continuous wattage of the device you plan to

use with the inverter. The Instant Power™ must be used with devices

drawing 400 watts or less. If the wattage is not marked on the device, use

only devices that draw less than 4 Amps of AC current.
Devices like TVs, fans or electric motors require additional power to start

(commonly known as the “starting or peak power”). The Instant Power™

can supply a momentary surge in wattage; however even devices rated

less than the maximum 400 watts can exceed the inverters surge capabil-

ity and cause an automatic overload shutdown.
Do not use the inverter with a product that draws a higher wattage than

the inverter can provide, as this may cause damage to the inverter and the

product.
Make sure the device you are using is compatible with a modified sine

wave inverter.

Always run a test to establish whether the inverter will

operate a particular piece of equipment or device.
NOTE: In the event of a power overload, the inverter is designed to auto-

matically shut down. This safety feature prevents damaging the inverter

while testing devices and equipment with the 400 watt range.
NOTE: If powering more than one device, start one device at a time to

avoid a power surge and/or inverter overload. The surge load of each

device should not exceed the inverter’s continuous operation wattage rate.
Powering a 120V AC Device

5.4

To operate a 120V AC device:

Ensure the battery clips are securely clipped on the storage holders.

Plug the 120V AC device into the AC power outlet, and push the In-

verter Switch ON.

NOTE: the ChARgINg LED also functions as the INVERTER ON LED

. when you push the inverter switch to the ON position, the LED will

light.

If the device does not operate properly when first connected to the

inverter, push the inverter rocker switch ON (I), OFF (0), and ON (I)

again in quick succession. If this procedure is not successful, it is likely

that the inverter does not have the required capacity to operate the

device intended.
Charge the Instant Power™ as soon as possible after each use.

Risk of electric shock.

Incorrect operation of your inverter may result in damage and

personal injury. The inverter output is 120V AC and can shock or

electrocute the same as any ordinary household AC wall outlet.
