Ⅶ. 設置・配線のポイント
- 設置前, confirm that the coil voltage is 220-240V DC, matching the control power supply.
- For reversing control, ensure that the mechanical interlock of the two contactors (forward/reverse) is correctly installed to prevent phase-to-phase short circuit.
- 主回路配線: Connect L1, L2, L3 to the power supply, and T1, T2, T3 to the motor; pay attention to the phase sequence (when switching between forward and reverse rotation).
- 制御回路配線: Connect coil terminals A1 and A2 to the 220-240V DC power supply; pay attention to polarity (some models have no polarity requirements).
- 補助接点配線: The 1NC contact can be used for interlock control or status indication; pay attention to the rated current of the contact (usually 5A).
- Installation spacing: Keep a distance of at least 5mm from other components to ensure good heat dissipation.
- Pre-power-on inspection:
Check if the mechanical interlock operates flexibly and reliably
Check if the contacts are in good contact
Check if the coil wiring is correct
