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 40A.
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 the qualified personnel.
WARNING! It's necessary to connect AC input N wire. Otherwise, the inverter will NOT be able to detect
AC input.
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 recommended cable size as below.
