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 is32A for 3KW,40A for 4KW and 50A
for 5KW.
CAUTION!!
There are two terminal blocks with "IN" and "OUT" markings. Please do NOT-misconnect input and
output connectors.
WARNING!
All wiring must be performed by a qualified personnel.
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
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 3mm.
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.
