Notice:
1.The above table is only for your reference. In practice, the thick wire can be
replaced by two thin parallel wires if only the total section acreage of the wire meets
the requirements.
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, it can increase the acreage of the section or reduce the
length of the lead. The recommended length of lead is less than 1m.
3.Connect cathode wire of the battery to the cathode terminal (black) on the back
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 connected 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-temperature 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 ofthe
inverter directly.

The ground terminal has already connected to the ground wire of AC output
receptacle through the internal connecting wire. The ground terminal must be
connected to the ground wire, which will vary depending on where the power
inverter is installed. In a vehicle, connect the ground terminal to the chassis of the
vehicle. On the ship, connect the ground terminal to the ship grounding system; In
a fixed position, connect the ground terminal to the earth.
Warnings:
● To make sure the firmness of the connection. The ground wire must be 14AWG
（
2.08mm

）
or even larger.
● Do not operate the power inverter without connecting to ground. Electric shock
hazard may result.
2). Connect to the battery
(1).Please do all the safety precautions before connection, then check whether the
battery voltage is in accordance with the input voltage of the inverter. Only the
voltage of battery according with the requirements can be allowed to connect with
the inverter.
(2).The connecting wire must be big enough to bear current, or else the inverter can
not support big load because of voltage reduce caused by the small cross-sectional
wire. Depending on the below table, please select the
input DC wire or larger one.
