6. Installation
Disconnect all power before work.
Bolt reactor firmly to a flat, rigid mounting surface.
Connect 3‑phase AC to input terminals (L1/L2/L3).
Connect output terminals to drive unit power input.
Ground the housing with a low‑resistance earth wire.
Torque all terminals securely; test power‑on operation.
7. Maintenance & Troubleshooting
Clean dust; check terminals every 3–6 months.
Retighten terminals if loose.
Overheating: Check load current and ventilation.
Loud hum: Inspect core/coil clamping.
Voltage fluctuation alarms: Verify wiring and model compatibility.
8. Safety Precautions
Installation/service only by qualified electricians.
Always cut power before access—risk of electric shock.
Do not touch hot surfaces during operation.
Maintain minimum 50 mm clearance around reactor for cooling.
