Dimensions andTorque Specs

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 mm2 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. kcmil = 1,000 circular mils, a measure of wire cross-sectional area

mm2 = square millimeters, a measure of wire cross-sectional area
