Wiring Instructions

(1) Always connect the power supply (for main circuit inputs) and power
input terminals R/L1, S/L2, and T/L3 (R/L1, S/L2 for single-phase) via a
molded-case circuit breaker (MCCB) or a fuse. Never connect them to
terminals U/T1,V/T2,W/T3, B1, B2, -, +1, or +2. The inverter may be
damaged.
Refer to page 148 for Recommended Peripheral Devices.
For single-phase inverters, always use terminal R/L1 and S/L2.
Never connect to terminal T/L3.

(2) Connect the motor wiring to terminals U/T1, V/T2, W/T3 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 (n080)" on page 67.
(4) Control wiring must be less than 50m (164ft) in length and separate from
the power wiring. Use twisted-pair shielded wire when inputting the fre-
quency signal externally.
(5) Tighten the screws on the main circuit and control circuit terminals.
(6) Do not connect or disconnect wiring, or perform signal check while the
power supply is turned ON.
(7) For 400V class inverters, make sure to ground the supply neutral to con-
form to CE requirements.
(8) Only basic insulation to meet the requirements of protection class 1 and
overvoltage category II is provided with control circuit terminals.
Additional insulation may be necessary in the end product to conform to
CE requirements.
(9) A closed-loop connector should be used when wiring to the main circuit
terminal.
