WARNI NG: Shock Hazard
Installation must be performed with care due to high battery voltage in series.
CAUTI ON!!
Do not place anything between the flat part of the inverter terminal and the ring
terminal. Otherwise, overheating may occur.
CAUTI ON!!
Do not apply anti-oxidant substance on the terminals before terminals are
connected tightly.
CAUTI ON!!
Before making the final DC connection or closing DC breaker/disconnector, be sure
positive (+) must be connected to positive (+) and negative (-) must be connected to negative
(-).
AC I nput/ Output Connection
CAUTI ON!!
Before connecting to AC input power source, please install a
separate
AC breaker between
inverter and AC input power source. This will ensure the inverter can be securely disconnected during
maintenance and fully protected from over current of AC input. The recommended spec of AC breaker is 30A
for 3.2KVA, 50A for 5.2KVA.
CAUTI ON!!
There are two terminal blocks with “IN” and “OUT” markings. Please do NOT mis-connect input
and output connectors.
WARNI NG!
All wiring must be performed by a qualified personnel.
WARNI NG!
It’s very important for system safety and efficient operation to use appropriate cable for AC input
connection. To reduce risk of injury, please use the proper recommended cable size as below.

Please follow below steps to implement AC input/output connection:
1.
Before making AC input/output connection, be sure to open DC protector or
disconnector first.
2.
Remove insulation sleeve 10mm for six conductors. And shorten phase L and
neutral conductor N 3 mm.
3.
Insert AC input wires according to polarities indicated on terminal block and
tighten the terminal screws. Be sure to connect PE protective conductor (
)
first.
