SJ200 Inverter

Terminal Dimensions and Torque Specs

The terminal screw dimensions for all SJ200 inverters are listed in table below. This 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.

Wire the Inverter Input to a Supply

Step 6: In this step, you will connect wiring to the

6input 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 wiring example to the right shows an SJ200 inverter wired for 3-phase input. Note the use of ring lug connectors for a secure connection.
