5. Installation and Maintenance Guidelines
Pre-Installation Inspection
- Confirm that the power supply voltage and wiring terminals match the module specifications.
- Check that the heat sink is securely installed to ensure a good contact surface.
- Verify that the wiring of communication interfaces (Ethernet, CAN) complies with protocol requirements such as IEC 61850/Modbus.
Mechanical Installation
- Use standard DIN-Rail or cabinet mounting holes and keep the module horizontal.
- Maintain a minimum ventilation space of 30 mm around the module to prevent local overheating.
Electrical Wiring
- Connect the main circuit, gate drive, and signal loop in accordance with the wiring diagram provided by ABB.
- Use special insulating tools for high-voltage terminals to ensure safe spacing.
Commissioning and Testing
- Perform no-load testing before initial power-on to confirm normal communication links.
- Set operating parameters (voltage range, current limit, protection threshold) via ABB’s configuration software (e.g., Automation Builder).
- Monitor key indicators such as temperature, gate current, and switching frequency during operation to ensure they are within the rated range.
