New Module Installation Guidelines
5.1 Pre-installation Preparation
Cut off medium voltage main power and cabinet 24VDC auxiliary power; confirm model and part number match purchase order; inspect module for water leakage, damage and fiber connector integrity. Wear anti-static wristband and insulated safety tools. Prepare torque wrench, deionized water pipeline fittings, fiber optic cable and ACS6000 commissioning laptop.
Safety reminder: High voltage danger. Only certified medium voltage drive technicians are allowed to perform replacement.
5.2 Installation Steps
- Confirm cabinet earthing is reliable; pull out the old phase module from the drawer rack.
- Insert S-093H module slowly along drawer guide rail until fully seated; engage mechanical interlock.
- Torque the main copper busbar connection bolts to specified value for low contact resistance.
- Connect inlet/outlet deionized cooling water pipes; tighten fittings and perform pressure leak test.
- Install fiber optic cables between GDU and main control unit; avoid sharp bending of optical fiber.
- Wire 24VDC auxiliary control power; tighten terminals, confirm polarity correct and no bare copper exposure.
- Check water flow, interlock switch and all sensor wiring before closing cabinet door.
5.3 Post-installation Commissioning
Restore 24VDC auxiliary power, keep medium voltage disconnected; energize module and observe LED indicators to confirm GDU self-test passes. Run diagnostic software, read temperature, water flow and sensor values. Execute fiber communication test and protection function simulation. Perform dry-run test without main high voltage. Run continuous 60-minute stability test; verify no leakage and no fault alarm before applying medium voltage and full-load online operation.
