Dimensions and
Torque 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 mm
2
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
mm
