Wire the Inverter Input to a Supply

Step 6: In this step, you will connect wiring to the input of the inverter. All models have the same power connector terminals [R(L1)], [S(L2)], and [T(L3)] for three-phase input. The three phases may be connected in any order, as they are isolated from chassis ground and do not determine motor direction of rotation.

Please refer to the specifications label (on the front or side of the inverter) for the acceptable input voltage ranges!

NOTE: The wiring example to the right shows an SJ300-037LFU inverter. The terminal locations will vary, depending on the inverter model (see below). Note the use of ring lug connectors for a secure connection.

Please use the terminal arrangement below corresponding to your inverter model.
