The following tables list the screw size of terminal and recommended torque for tightening for
each of the L300P 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
