Note 1: Field wiring must be made by a UL-listed and CSA certified ring lug terminal
connector sized for the wire gauge involved. The connector must be fixed by using
the crimping tool specified by the connector manufacturer.
Note 2: Be sure to consider the capacity of the circuit breaker to be used.
Note 3: Be sure to use a larger wire gauge if power line length exceeds 66 ft (20m).
Note 4: Prepackaged (included) square washer is to be used when the bare wire is directly
connected to terminal without using crimp contact (such as ring lug connector).
Note 5: When replacing J300-055HF or SJ300-055HFF2 inverter with SJ700-055HFF2,
you may use power wiring size 2mm
Note 6: Wire must be rated for operation up to 75°C.
