5. WIRING
• Wiring Instructions
(1) Always connect the power supply via a molded-case circuit breaker (MCCB) to the power input terminals R/L1, S/L2, and T/L3 (R/L1, S/L2 for single-phase). Never connect the power supply to U/T1, V/T2, W/T3,-,+1 or +2.
The single-phase (200V class) inverter can be connected to a 200V 3-phase input.
However, when a single-phase supply is used, never use the terminal T/L3 for other purposes.

(2) Connect the motor wiring to terminals U, V, and W on the main circuit output side
(bottom of the inverter).
(3) If the wiring distance between inverter and motor is long, reduce the inverter carrier frequency. For details, refer to “Reducing motor noise or leakage current
(n46)” on page 79.
(4) Control wiring must be less than 164ft(50m) in length and separate from the power wiring. Use twisted-pair shielded wire when inputting the frequency signal externally.
(5) Tighten the screws on the main circuit and control circuit terminals.
(6) Do not connect or disconnect wiring, or perform signal checks while the power supply is turned ON.
