Terminal Dimensions and Torque Specs
The terminal screw dimensions for all SJ200
information is useful in sizing spade lug or ring lug connectors for wire terminations.
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.

When connecting wiring, use the tightening torque listed in the following table to safely
attach wiring to the connectors.
Screw Tightening Torque
M2 0.2 N•m (max. 0.25 N•m) M3.5
M3 0.5 N•m (max. 0.6 N•m)
Wire the Inverter Input to a Supply
Step 6: In this step, you will

connect wiring to the input of the
inverter. First, you must determine
whether the inverter model you
have requires three-phase power
only, or if it can accept either
single-phase or three-phase power.
All models have the same power
connector terminals [R/L1],
[S/L2], and [T/L3]. So, you must
refer to the specifications label
(on the side of the inverter) for
the acceptable power source
types! For inverters that can
accept single-phase power and
are connected that way, terminal [S/L2] will remain unconnected.
The examples above show single-phase and 3-phase input wiring. Note the use of ring
lug connectors for a secure connection.
