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 10A
for 1KVA, 20A for 2KVA, 32A for 3KVA , 40A for 4KVA 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! 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.

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 (

L→LINE (brown or black)
N→Neutral (blue)
