5. Precautions for Installation and Use

1. Power Matching
   Ensure the soft starter’s rated current and voltage meet or exceed the motor’s requirements.

2. Correct Wiring
   Follow wiring diagrams for power, control and communication connections.

3. Proper Grounding
   Provide reliable grounding to minimize interference and enhance stability.

4. Suitable Environment
   Install in a dry, clean, and ventilated location free from corrosive gases.

5. Adequate Cooling
   Allow sufficient clearance for airflow and heat dissipation; add fans if needed.

6. Professional Parameter Setup
   Parameter setting should be performed by trained personnel according to application requirements.

7. Routine Inspection
   Periodically inspect terminals, cooling conditions, and logged events to ensure healthy operation.
