(6) Reverse connection of the polarities or short circuit will burn the fuse or result in

permanent damage of the internal elements of the inverter.

(7) Remove all rings and jewelry when working around your inverter.

(8) Although there is over-voltage protection, it may also cause damage to the inverter

if the input voltage is too high.

3) Connecting the load

This inverter provides 2 ways to connect the ac.

This most common method is to simply plug in your equipment into one of the GFCI

protected outlets.

This inverter also provides a direct connect terminal block (only for model

PWRI300012120S). If you wish to hardwire a piece of equipment or power strip to this

inverter you may do so. Please be careful. Make sure inverter is OFF and no power is

on the terminal block. We provide a 3 wire connection where black is load or hot, white

is neutral and green is ground or earth. Make the 3 connections. Ensure there is no

short between any of these connections and that they are secure. Reversing these

wires may cause damage to both inverter and your equipment. If you are not sure, you

should hire a qualified electrician.

Warnings:

(1) Make sure that the switches of the inverter and the appliances are in the OFF

position before connecting.

(2) Check the power cord. If it is damaged, don't use.

7. Usage

①. How to use the inverter

1) Check the output voltage and capacity of the battery to make sure it is in accord with

the requirements of the product.

2) Connect the battery and the DC cable of the inverter to ensure that the polarities are

not connected reversely and are tight.

3) Power on inverter: Press the power switch of inverter or remote for over 0.5s and

release. If the indicator light on the inverter or on the remote control box is on, it

means that the inverter started to work normally. This method can avoid turning on

the unit by mistake due to accidental touch.

4) Turn the main power to inverter and appliances OFF. If you are not going to use the

ac terminal block, you may plug in your ac equipment into the GFCI sockets and

turn the inverter on and then your equipment. They should be operating as if you

were plugged into city power.

If you wish to use the terminal block (only for model PWRI300012120S), you

should follow these procedures:

A. You will need a 3 wire (10 Awg recommended Black, White, Green) ac cables

which are not provided with this product. Measure the required length for your

Particular application.

B. Connections to the inverter will require you to strip 3/8 inch to bare wire and we

prefer those to be soldered to avoid potential short circuit caused by lose strands

crossing over. You will wrap the wire around the appropriate bolt (Black to L, White

to N, Green to G). You may also use a ULug no wider than 3/16 inch

C. The other end will connect to either a socket, power strip or your load directly.

Now you may turn on the inverter and you equipment as they are ready for

use.

5) The cooling fans inside the inverter do not work until the case temperature rises up

to about 104°F.

6) Switch off inverter or remote to turn off. At that time, the indicator lights for both

inverter and remote are off. The inverter does not consume current from the battery

when it is switched off.

②. How to use USB power supply

This model supplies a USB output, and provides stable voltage at 5V DC, maximum

current 2.1A directly to a portable device with USB port.

Notice: Before using the USB power supply, please make sure the device can be

charged by USB and the maximum working current is no more than 2.1A.

8. About soft start technology

The output voltage rises up from low to normal when the inverter is turned on. This

can reduce high startup currents, which can make startup easier for large inductive

loads.

As for the large inductive loads, such as electric tools and capacitive loads, we

suggest turning on the switch of the appliance firstly and then the inverter's. The soft

start may be enough to power the high startup.

9. The output wave form

The output wave form of this inverter is a Pure Sine Wave, which is similar to utility-

supplied AC electricity. Pure sine wave is applicable in most loads, including electrical

equipment, such as Linear Adaptor, switching power supply, transformer, motor and so

on.

Compared to Modified wave form, for inductive loads such as a refrigerator and

electric fans, pure sine wave form can improve its power factor and the battery's

efficiency and reduce working noises. For capacitive loads such as adapter of lap-top,

pure sine wave can lower the rush current at work and reduce interferences to

increase reliability and prolong the life of the product.
