Installation & Maintenance Recommendations
- Wiring Requirements: Strictly follow the electrical drawings during wiring to ensure correct power phase sequence. Distinguish wiring for the main circuit and control circuit carefully.
- Grounding: Proper grounding is mandatory during installation to prevent electric leakage caused by insulation damage.
- Overload Relay Calibration: Adjust the trip current of the overload relay according to the motor’s rated current, usually set to 115%-125% of the rated current.
- Regular Inspection: Check contact wear regularly, and clean or replace worn parts as needed.
- Environmental Requirements: Avoid installation in environments with corrosive gases, excessive dust or extremely high temperatures.
