Maintenance
- Routine inspection: Check PCB dust, connector tightness, fiber port cleanliness every 6–12 months
- Clean the board surface with dry compressed air; liquid solvent cleaning is strictly prohibited
- ESD protection must be used during disassembly and inspection, anti-static wristband required
- Check optical fiber for scratches or aging; poor fiber communication will cause drive fault
- Do not power on if PCB burn marks, corrosion or condensation are found
- We support function testing, refurbishment and spare replacement service for this gate drive board
Installation
- Cut off all high voltage and auxiliary power supply of the converter, confirm zero voltage before operation.
- Wear anti-static wristband to prevent electrostatic damage to PCB components.
- Open converter cabinet cover, release locking mechanism of old gate drive board.
- Disconnect optical fiber cables and power terminals carefully, pull out old board.
- Align new 3BHB027204R0001 board with cabinet guide rail, insert smoothly and lock.
- Reconnect optical fiber and all terminals, ensure fiber connectors are fully seated.
- Inspect cabinet for loose wires or foreign objects, close cabinet cover.
- Power on step by step, perform system self-test, verify trigger signal and fault protection function.
- Run no-load commissioning before full-load operation.
