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 32A for 3KVA and 50A for 5KVA.
There are two terminal blocks with “IN” and “OUT” markings. Please do
NOT mis-connect input and output connectors.
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.
Be sure that AC power source is disconnected before attempting to
hardwire it to the unit.
