(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.
