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
for 3KVA.
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 very important for system safety and efficient operation to use appropriate cable for AC input
