The following tables list the screw size of terminal and recommended torque for tightening for 
each of the SJ300 inverter models (400V models are on the next page).

CAUTION: Fasten the screws with the specified fastening torque in the table below. Check for 
any loosening of screws. Otherwise, there is the danger of fire.

Note 1: The recommended ring lug connector listing consists of wire size – screw size 

format. The wire sizes are in AWG or mm

 format. For AWG wire sizes, bolt sizes 

for the ring lug centers are: #10, #12, 1/4”,  5/16”, and 1/2”. For metric wire sizes, 
bolt sizes for the ring lug centers are: 6 = 6M, 8 = 8M, 10 = 10M.

TIP: AWG = American Wire Gauge. Smaller numbers represent increasing wire thickness.
