2.3.2 Connecting the power cable
There are two types of power cables that can be used to connect to the inverter.
*Either the single-phase input type or three-phase input type cable is used depending on your power supply.
The single-phase input type is also further separated in 200V and 100V inputs. The output in either case is three-phase at 200V.
Single-phase two-wire power supply
This power supply is used for home electric appliances and small electric equipment.
The power supply is connected to the main circuit terminals R and S, and the motor is connected to terminals U, V,
and W.

Three-phase three-wire power supply
This power supply is for large electric equipment in factories.
The power supply is connected to the main circuit terminals R, S, and T, and the motor is connected to terminals U, V,
and W.

● Make sure the power cables are connected to the R/L1, S/L2, and T/L3 terminals. (Phase need not be matched.)
Never connect the power cable to the U, V, and W terminals on the inverter. Doing so will damage the inverter.
● Do not touch the main circuit terminals directly as this could cause electric shock.
