Environment: Avoid direct sunlight, moisture, corrosive gases, and excessive vibration.
ESD Protection: Use anti-static wristband when handling (static-sensitive PCB).
Cable Separation: Separate high-voltage cables from low-voltage communication cables by ≥10 cm.
5.2 Terminal Wiring (Simplified)
| Terminal Group | Description | Wire Gauge |
|---|---|---|
| Auxiliary Power | ||
| 1–2 | 24 VDC (+/−) | 1.5 mm² |
| 3 | Chassis ground (PE) | 2.5 mm² |
| Ethernet | ||
| 4–5 | RJ45: Ethernet link (TCP/IP) | CAT5e/CAT6 |
| CAN Bus | ||
| 6–7 | CAN1 (H/L) | 1.0 mm² (twisted-pair) |
| 8–9 | CAN2 (H/L) | 1.0 mm² (twisted-pair) |
| RS485 | ||
| 10–11 | RS485 (A/B) | 1.0 mm² (twisted-pair) |
Bus Cable: Use twisted-pair shielded cable for CAN/RS485; ground shield at one end only (PCM5-1 side).
Terminal Torque: Tighten terminals to 0.8–1.0 Nm to prevent loose connections and overheating.
Fusing: Protect 24 VDC supply with a 5 A slow-blow fuse.
5.3 Jumper & Switch Settings
Node Address: Set via rotary switch (1–F, hex); unique for all modules in the rack.
CAN Termination: Jumper-selectable 120 Ω termination (enable at bus ends).
RS485 Mode: Jumper for 2-wire (default) or 4-wire communication.
6. Front Panel & Operation
6.1 Front Panel Layout
LED Indicators (Left to Right)
POWER: On = 24 VDC supply OK.
