6. Installation & Wiring

1. Power Off: Disconnect rack power before insertion/removal.

2. Rack Slot: Insert module into designated UCN/APM slot; secure latch.

3. Cabling: Use shielded Ethernet cable (CAT5e/CAT6).

4. Grounding: Shield ground at cabinet end only (avoid ground loops).

5. Separation: Keep comms cables ≥ 30 cm from high‑voltage AC lines.

7. LED Indicator Description

• PWR (Green): On = 24 VDC power normal

• RUN (Green): Flashing = normal communication

• FLT (Red): On = fault (comm loss, config error, overload)

8. Maintenance & Troubleshooting

• Inspect: Quarterly check connectors, coating, physical damage.

• Clean: Dry cloth only; no liquid cleaners.

• Fault Handling:

  • FLT on: Verify cabling, port status, and UCN configuration.

  • Check backplane power and network termination.

• Replacement: Use only original Honeywell modules; power off first.

9. Safety Precautions

• Electrical: Disconnect all power before wiring/maintenance.

• Environmental: Avoid moisture, dust, corrosive gases beyond ratings.

• Modification: Do not alter hardware/firmware; use OEM replacements.
