6. Installation and Maintenance
Installation Steps
- On-site Survey: Determine the protection level requirements (IP20 or IP54) of the installation location.
- Positioning and Installation: Choose wall-mounted or floor-mounted installation according to on-site conditions.
- Cable Wiring: Connect the power lines and control lines according to the wiring diagram to ensure firm crimping.
Maintenance Points
- Regular Inspection: Regularly check the tightness of cable terminals and screws to prevent poor contact caused by vibration.
- Cleaning and Protection: Keep the cabinet surface clean to prevent dust from entering internal components.
- Function Test: Regularly conduct trip and closing tests to ensure that protective components such as circuit breakers function normally.
