Wire the Inverter Input to a Supply
In this step, you will connect wiring to the input of the inverter. First, you must determine
whether the inverter model you have required three-phase power only, or single-phase
power only. All models have the same power connection 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.
Note the use of ring lug connectors for a secure connection.
Single-phase 200V 0.1 to 0.4kW
Three-phase 200V 0.1 to 0.75kW
Single-phase 200V 0.75 to 2.2kW
Three-phase 200V 1.5, 2.2kW
Three-phase 400V 0.4 to 3.0kW
