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 4KW~6KW, 80A for 8KW~12KW.
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.
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.
