Most electrical tools, appliances and audio/video equipment have labels that show the unit's power consumption in

amps, watts, or both. To avoid inverter shutdown and possible damage to the inverter, avoid exceeding the wattage

rating of this unit. To obtain a rough estimate of the current (in amperes) the power source must deliver where

the power consumption of the tool or device is given in watts AC, simply divide the power consumption of the

load by 10. Example: If a load is rated at 200 watts AC, the power source must be able to deliver: 200 divided

by 10 = 20 amperes.

The inverter has built-in overload protection so that if you do exceed the inverter's output capacity continuously,

the unit will automatically shut down. Once the excessive load is removed, the inverter can be restarted and

resume normal operation.

Note: To restart the inverter, turn it off, and then on again. The on/off Switch is located on the unit's

Front Panel (refer to the "Control and Functions" section of this Instruction Manual).

The inverter powers resistive loads the easiest; however, larger resistive loads, such as electric stoves or

heaters, could draw more wattage than the inverter can deliver on a continuous basis.

CAUTION: TO REDUCE THE RISK OF PROPERTY DAMAGE:

Ensure that total continuous power consumption of all tools and/or appliances connected to the inverter (and in

use) does not exceed the inverter's continuous watts rating. Also ensure that start-up wattage for inductive

loads does not exceed peak watts for more than a second.

Appliances such as microwave ovens will normally draw more than their rated current and could possibly

overload the inverter when operating simultaneously with other appliances. For example: A 600 watt

microwave oven draws approximately 940 watts.

The following chart shows the approximate amperage and corresponding wattage at 120 volts AC for various

common tools and appliances.
