6. Installation and Maintenance Recommendations
- Installation Environment: Should be installed in a well-ventilated and dry cabinet, avoiding high temperature and humid environments.
- Wiring Inspection: Before power-on, be sure to check whether the jumpers (JP1-JP7) and terminal block connections are firm to prevent faults caused by poor contact.
- Regular Maintenance: Regularly check the status of components such as capacitors and relays on the board, and replace aging components in a timely manner.
- Safety Notes: Due to its high working voltage (600V AC), strict compliance with high-voltage operation specifications is required during maintenance, ensuring that the power supply is disconnected before operation.
