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 32A for 1KW/3KW.
CAUTION: There are two terminal blocks with ‘IN’ and ‘OUT’ markings. Please do NOT mis-
connect 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:
Before making AC input/output connection, be sure to open DC protector or disconnector first.
Remove insulation sleeve 10mm for six conductors. And shorten phase L and neutral conductor N 3
mm. Insert AC input/output wires according to polarities indicated on terminal and tighten the
terminal screws.
Be sure to connect PE protective conductor first.
