Wiring diagram
Modular RCU chassis engineering wiring reference — main control board, expansion slots, and RS485/CAN bus topology; refer to signed drawing set for terminal details.
Installation notes
- Slot and module models must be specified line-by-line in the BOM (relay/dimming/HVAC, etc.)
- Modular chassis recommended for standard low-voltage cabinet installation; single-board replacement requires power-off
- Wire per project drawing; signed projects use factory shipment drawings
- After power-on, commission slot by slot: module identification, bus communication, and output action acceptance
