6. Installation and Maintenance Guidelines

Step	Key Points
Preparation	Confirm that electrical parameters match the system; prepare anti-static wristbands, ground wires, professional multimeters, and other tools.
Mechanical Fixation	Use bolts to firmly install the module in the rack or cabinet, ensuring tight contact between the heat sink and the radiator.
Electrical Connection	Connect input power, gate trigger signals, ground, and control signals according to the wiring diagram provided by ABB.
Heat Dissipation System	Select water cooling or forced air cooling based on rated power; check if heat sinks, fans, or cooling pipelines are unobstructed.
First Power-On	Perform low-voltage pre-inspection, then gradually increase the voltage, and monitor current, temperature, and gate trigger waveforms.
Regular Inspection	Conduct inspections every 6 ~ 12 months:   • Wiring tightness   • Radiator cleanliness   • Ambient temperature within the rated range   • Abnormal noise or overheating
Fault Diagnosis	Professional test equipment (oscilloscopes, power analyzers) and ABB technical support are required; on-site replacement of internal semiconductor chips is not recommended.
