5. MAKING DC WIRING CONNECTIONS
Follow this procedure to connect the battery cables to the DC input terminals of the inverter. Your cable should be as short as possible
﹙ideally to use factory spare cables﹚ enough to handle the required current in accordance with the electrical codes or regulations
application. Cables are not an adequate gauge﹙ too narrow﹚ or too long will decrease the inverter performances such as poor surge
capability and low input voltage warnings frequently and shutdowns. UVP warning presents due to DC voltage drop across the cables
from the inverter to the batteries.
The longer or narrower the cables, the greater the voltage drop.
Increasing your DC cable size will help improve the situation.
Warning
The installation of a fuse must be on positive cable. Failure to place a fuse on “+” cables running between the inverter and battery may
cause damage to the inverter and will void warranty.
6. TROUBLE SHOOTING
Warning
Do not open or disassemble the inverter. Attempting to service the unit yourself may result in a risk of electrical shock or fire.
7. MAINTENANCE
You should clean the exterior of the unit periodically with a damp cloth to prevent accumulation of dust and dirt. At the same time,
tighten the screws on the DC input terminals.

Code Solution
Battery low voltage
01
Stop using the inverter and to charge the bat-
tery;Replace a thicker connection cable.
Battery over voltage
02
Check the battery voltage is right; Check the
charging voltage
Front-end circuit over temperature
03
Improve ventilation;Make sure the environment
temperature is between 0~40ºC; Reduce
or turn off the loads for a while to lower the
temperature
Back-end circuit over temperature
04
Front and backend over temperature
05
Output overload
08
Make the loads power is smaller than rated
power (Inductive or capacitive loads are seve-
ral times than the rated power when starting,
please replace higher power inverter)
Output short circuit
09
Disconnect the loads and check if it is short
