Installation & Maintenance Guidelines

Installation

• Adopt standard DIN-rail or cabinet mounting, ensuring the module is fixed horizontally.
• Follow ABB’s recommended wiring diagram for connections, with gate, anode, and cathode corresponding to dedicated terminals.
• Equip with a heat sink that meets the rated power, ensuring good thermal conductivity between the heat sink and the module.

Electrical Wiring

• Use cables complying with IEC 61800-5-1 standard, with cross-sectional area matching the rated current.
• Use shielded cables for gate drive signals to avoid electromagnetic interference.

Commissioning

• Check all terminals for secure contact and no short circuits before initial power-on.
• Monitor key parameters such as on-state voltage drop and switching time using ABB’s diagnostic software or on-site instruments.

Maintenance

• Regularly inspect heat dissipation devices for dust accumulation and check if heat sinks are loose.
• Monitor module temperature to ensure it does not exceed the rated upper limit.
• Replace or send for factory repair promptly if abnormal switching noise or overcurrent alarms occur.

Safety

• Cut off power supply and wear qualified insulating protective equipment before operation.
• Comply with local electrical safety regulations and ensure reliable grounding.
