Ⅲ. Safety Precaution

4
Do not obey the preventive rules, you may hurt yourself or destroy the inverter
and your electric appliance.
1. Please pay attention to all the warning marks and obey to it, when you operate
the inverter.
2. Please make sure you have use the three phase plug when you need it and
examine if the inverter connects with the battery correctly
3. When the inverter need move or be reconnected, please make sure that the
inverter have stop. If not ,the output port may be electrification, you may get
electrocuted,
Danger! Electricity!
Our inverter output 220VAC power, and the output port may be electrification.
So do not insert anything into the output port except for the plug.
Do not get close to the inflammable and explosive dangerous goods
The locations of the inverter should be far away from the inflammable and
explosive dangerous goods
Do not dismantle the inverter
Dismantling or refitting the inverter, you may have a very dangerous accident.
Do not connect the inverter to the wrong place
Do not connect the inverter to AD power, such as your home use power.
Choose the Proper Battery
According to the inverters’ specification, inverter should connect with standard
12V/24V/48V/60V DA power.
Choose the Proper Wire
Choose wire with the proper wire diameter to bear the corresponding current to
avoid be fused.

Keep Good Ventilation and Heat Dissipation
Inverter would generate heat when working, so do not make inverter close to the
thermal sensitive goods.And at the same time do not put anything on the inverters’
housing to keep heat dissipation holes and fan good ventilation.
Keep Dry
Inverter should keep away from the environment where is wet and closes to water.
Keep button off when cleaning, then clean with dry rag (wet rag can’t be used)
Keep the Wire be Connected Correctly.
The positive and negative terminals of the inverter should be connected to
the battery’s positive and negative terminals correctly. Otherwise it would blow
fuses. Inverter should shut off when it is out of state of use
Keep the Inverters locating in the Proper Environment.
Inverter should locate in cool environment, and the temperature should be
-15℃~60℃.
Children is forbidden close to it and juveniles is forbidden to use it
