CAUTION!!
Do not place anything between the flat part of the inverter terminal and the ring
terminal. Otherwise, overheating may occur.
CAUTION!!
Do not apply anti-oxidant substance on the terminals before terminals are
connected tightly.
CAUTION!!
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 Input/Output Connection
CAUTION!!
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 3KVA and 50A for 5KVA.
CAUTION!!
There are two terminal blocks with “IN” and “OUT” markings. Please do NOT mis-connect input
and output connectors.
WARNING!!
When using sockets as the output, please make sure that the current of each socket is less than
10A, in case of electric hazard.
WARNING!
All wiring must be performed by qualified person.
WARNING!
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.
Suggested cable requirement for AC wires

Torque Value
3KVA
12 AWG
1.2~ 1.6 Nm
5KVA
8 AWG
1.4~ 1.6Nm
Please follow below steps to implement AC input/output connection:
1.
Before making AC input/output connection, be sure to open DC protector or disconnect first.
2.
Remove insulation sleeve 10mm for six conductors.
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.
