BEFORE USING YOUR POWER INVERTER
3.
NOTE: 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 product.
When you turn on a device or a tool that runs on a motor, the device goes through two stages:
Start Up – Requiring an initial surge of power (commonly known as the “starting or peak
1.
load”).
Continuous Operation – Power consumption drops (commonly known as the
2.
“continuous load”).
The wattage (WATTS) or amperes (AMPS) can normally be found stamped or printed on most
devices and equipment, or in the user’s manual. Otherwise, contact the manufacturer to find
out whether the device you want to use is compatible with a modified sine wave.
To calculate the wattage: Wattage = AMPS x 120 (AC Voltage).
To calculate the starting load: Starting Load = 2 x WATTS. In general, the start up load of the
device or power tool determines whether or not your inverter has the capability to power it.
To calculate the continuous load: Continuous Load = AMPS x 120 (AC Voltage).
Always run a test to establish whether or not the inverter will operate a
particular piece of equipment or device. In the event of a power overload, the inverter is
designed to automatically shut down. This safety feature prevents damaging the inverter while
testing devices and equipment within the wattage range of the inverter.
If a device does not operate properly when first connected to the inverter, turn the inverter On/
Off switch ON, OFF, and ON 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 in
question.
This inverter uses a nonsinusoidal waveform. Therefore we do not
recommend you use it to power the following devices:
Switch Mode Power Supplies;
1.
Linear Power Supplies;
2.
Class 2 Transformers;
3.
Line Filter Capacitors;
4.
Shaded Pole Motors;
5.
Fan Motors;
6.
Microwave Ovens;
7.
Fluorescent and High Intensity Lamps (with a Ballast); and
8.
Transformerless Battery Chargers.
9.
Doing so, may cause the device to run warmer or overheat.
FASTENING THE INVERTER TO A FLAT SURFACE
4.
For your convenience, the inverter can be fastened to a flat surface, horizontally or vertically.
The area where the inverter is to be fastened must be dry, well ventilated and away from any
combustible material or fumes.
Turn off and disconnect the inverter.
1.
Place the back of the inverter with the mounting bracket against a flat, secure surface.
2.
Attach the inverter to the flat surface using corrosion resistant screws.
3.
CONNECTING INVERTER CABLES
5.
The inverter and power source must be in the OFF mode.
Make sure to connect the inverter to a 12 volt power supply only.
To avoid electrical shock, it is necessary to ground the inverter as well as the device powering
it. The inverter should be grounded using a #8 AWG copper wire (not included).
