4. In a Vehicle, boat or ship
ship.
Warnings:
● To make sure the firmness of the connection. The ground wire must be 14AWG (2.08mm
larger.
● Do not operate the power inverter without connecting to ground. Electric shock hazard may result.
2) Connect to the lead acid battery
(1) Please do all the safety precautions before connection, and then check whether the battery voltage is
in accordance with the input voltage of the inverter. Only the 12 voltage of the battery accords with the
requirements can be allowed to connect with the 12V inverter.
(2) Secure the provided Negative (black) DC cable connect to the Negative (-) bolt on the inverter, and the
other end to the Negative (-) post on the battery.
(3) Secure the provided Positive (Red) DC cable to the Positive (+) bolt on the inverter, and the other end
to the Positive (+) post on the battery.
(4) The nuts of the connection posts must be tightened to ensure well connected.
(5) Press the power switch for one second, because it is a long press type switch.
(6) The connecting wire must bear enough current. Depending on the table below, please choose the input
DC wire or larger one.

(2) In high current, the input DC wire may produce voltage drop, therefore, the operating voltage should be
subject to the value on the terminals. If the voltage drop is too large, you can increase the cross-sec-
tional area or reduce the length of the lead.
(3) Connect cathode wire of the battery to the cathode terminal (black) on the rear panel of inverter and
then connect the anode wire of the battery to the anode terminal (red) on the inverter, and fix them.
WARNINGS:
(1) Please wear eye patch and work clothes when working around the battery to avoid the acid and
corrosive objects harm your eyes and skin.
(2) Prepare enough water and soap. In case the acid materials contact eyes or skin, clean it by soap and
water as soon as possible. If the acid materials spay to your eyes accidentally, clean it by cold water
immediately and then sent to hospital.
(3) Do not put any combustible material in the location of installation for spark will result when it is connect-
ed to the battery.
(4) Keep good ventilation. The battery may produce a little inflammable gas when it works, so keep away
from the inverter and it is better to install them in different space.
(5) Fix the connecting wire of the input DC, or it will result the over-reduction of the voltage or over-tem-
perature of the wire.
(6) Reverse connection of the polarities or the short circuit will burn the fuse or result the permanence
damage of the internal elements of inverter.
(7) Take away the metal accouterment, such as ring or watch, when installation to avoid the short circuit.
(8) Although there is over-voltage protection, it may also cause damage of the inverter if the input voltage
is too high.
3) Connection of the AC appliance
Put the power plug of the AC appliance load into the output AC receptacle of the inverter directly.
Warnings:
(1) Make sure that the switches of the inverter and appliance power are in OFF position before connection.
(2) Check the power cord. If it is damaged, it should be connected after replacement.
4) Connection of theremote control box
Directly to the two ends of the cable respectively inserted into the inverter and wired remote control
remote control box on the interface.
7. USAGE
①. How to use 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 in tight connection.
3) Long press the switch or the remoter of inverter for over 0.5s and then stop, if the indicator light on the
inverter or on the remote control box is on, it means that the inverter starts to work normally. This
opening method can avoid turning on the unit by mistakes due to the interference or any factors.
4) Switch off electrical appliances and put its plug to the AC output socket of inverter. Then switch on
electrical appliance.
5) The cooling fans inside the inverter do not work until the case temperature rises up to about 40℃or the
load power is more than 40% of rated power.
