PRECAUTIONS FOR UL/cUL MARKING

• Do not connect or disconnect wiring, or perform signal checks while the
power supply is turned ON.

• The Inverter internal capacitor is still charged even after the power supply
is turned OFF. To prevent electric shock, disconnect all power before ser­vicing the Inverter, and then wait at least one minute after the power sup­ply is disconnected. Confirm that all indicators are OFF before
proceeding.

• Do not perform a withstand voltage test on any part of the Inverter. The
Inverter is an electronic device that uses semiconductors, and is thus vul­nerable to high voltage.

• Do not remove the Digital Operator or the blank cover unless the power
supply is turned OFF. Never touch the printed circuit board (PCB) while
the power supply is turned ON.

• This Inverter is not suitable for use on a circuit capable of delivering more
than 18,000 RMS symmetrical amperes, 250 V maximum (200 V Class
Inverters) or 18,000 RMS symmetrical amperes, 480 V maximum (400 V
Class Inverters).

CAUTION

• Use 75°C copper wire or equivalent.

Low voltage wires must be wired with Class I Wiring.

PRECAUTIONS FOR CE MARKINGS

• 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.

 Wiring Instructions

1. Always connect the power supply to the power input terminals R/L1,
S/L2, and T/L3 (R/L1, S/L2 for single-phase power) via a molded­case circuit breaker (MCCB) or a fuse. Never connect the power
supply to terminals U/T1, V/T2, W/T3, −, +1, or +2.
Refer to page 119 for recommended peripheral devices. For single­phase Inverters, always use terminals R/L1 and S/L2. Never connect
terminal T/L3.

Connect to R/L1,
S/L2, and T/L3.

2. Connect the motor wiring to terminals U/T1, V/T2 and 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 Using Carrier Frequency Selection (n46)
on page 64.

4. Control wiring must be less than 50 m in length and must be sepa­rated from the power wiring. Use shielded twisted-pair cable 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 check while
the power supply is turned ON.

7. For 400 V Class Inverters, always ground the supply neutral to con­form 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. Closed-loop connectors should be used when wiring to the main cir­cuit terminals.

10.Voltage drop should be considered when determining the wire size.

Voltage drop can be calculated using the following equation:

Phase-to-phase voltage drop (V)
= × wire resistance (Ω/km) × wiring distance (m) × current

-3

(A) × 10

Select a wire size so that voltage drop will be less than 2% of the
normal rated voltage.
