Wiring Instructions
1. Always connect the power supply for the main circuit
inputs to the power input terminals L1, L2, and L3 of the
input filter via a molded-case circuit breaker (MCCB) or a
fuse. Never connect the power supply to terminals U/T1,
V/T2, W/T3, B1, B2, , +1, or +2. The inverter may be
damaged.
For single-phase Inverters, always use terminals L and N
of the input filter. Fuses must be of UL-class RK5 fuse or
an equivalent.
Refer to page 222 for recommended peripheral devices.

2. If the wiring distance between Inverter and motor is long,
reduce the Inverter carrier frequency. For details, refer to
Carrier Frequency Selection (n080)14kHz max on page
89.
3. Control wiring must be less than 50 m (164 ft) in length
and must be separated from power wiring. Use shielded
twisted-pair cable when inputting the frequency signal
externally.
4. Only basic insulation to meet the requirements of protec-
tion 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 require-
ments.
5. Closed-loop connectors should be used when wiring to the
main circuit terminals.
