5. Installation

1. Disconnect all power before installation.

2. Mount horizontally on a flat, rigid cabinet surface; secure with M5 bolts.

3. Connect 3‑phase AC input to reactor terminals (L1/L2/L3 IN).

4. Connect reactor output (L1/L2/L3 OUT) to drive power input.

5. Ground the housing (PE terminal) with low‑resistance earth wire.

6. Torque terminals to 1.2–1.5 N·m; verify tightness periodically.

7. Maintain ≥50 mm clearance around reactor for ventilation.

6. Maintenance & Troubleshooting

• Routine check: Clean dust; inspect terminals every 3–6 months.

• Overheating: Check load current (≤35 A), ventilation, and ambient temperature.

• Excessive hum: Retighten core/coil clamping bolts; check for loose terminals.

• Voltage fluctuation alarms: Verify wiring, phase sequence, and model compatibility.

• Insulation failure: Test winding‑to‑ground insulation (≥1 MΩ at 500 V DC).

7. Safety Precautions

• Installation/service only by qualified electricians.

• Always cut power before access—risk of electric shock.

• Do not touch hot surfaces during/after operation.

• Keep away from flammable materials.

• Use only specified torque values to avoid damage.
