6. Installation Instructions

1. Power Off: Disconnect power to the Momentum I/O base.

2. ESD Protection: Use an anti‑static wristband when handling the adapter.

3. Mounting: Align 171CCC98030 with the I/O base connector; press firmly until seated. Tighten the mounting screws.

4. Wiring:

   • Ethernet: Connect CAT5e/CAT6 cable to the RJ45 port (10/100 Mbps auto‑sensing).

   • RS‑485: Connect 2‑wire shielded cable to the Modbus terminals; install a 120 Ω terminating resistor at the bus ends if required.

5. Power Up: Apply 5 V DC power. Check LEDs: PWR ON, RUN blinking (program execution), LAN/MBUS blinking (activity).

6. IP Configuration: Use BootP Lite or EcoStruxure Control Expert to set IP address, subnet mask, and gateway.

7. Programming: Download IEC 61131‑3 program via EcoStruxure Control Expert (Unity Pro) or LL984 program via Concept, ProWORX 32, or Modsoft.

• Network: Modbus TCP/IP (Ethernet), Modbus RTU/ASCII (RS‑485)

• Replacement: Directly replaces 171CCC98020 (compatible mounting and wiring)

8. Safety & Handling

• Installation and maintenance must be performed by qualified personnel in accordance with local electrical codes.

• Disconnect power before wiring or maintenance to avoid electric shock.

• Avoid exposure to water, moisture, corrosive substances, and direct sunlight.

• Use ESD protection to prevent static damage to electronic components.

• Do not open the casing; no user‑serviceable parts inside.

• Ensure proper ventilation to maintain operating temperature within specifications.

9. Maintenance & Troubleshooting

• Inspection: Quarterly check for cracks, loose screws, damaged connectors, and LED operation.

• Cleaning: Use a dry, lint‑free cloth only; do not use solvents or abrasive cleaners.

• Common Issues:

  • PWR Off: Check 5 V DC supply from the I/O base; verify power connections.

  • FLT On: CPU fault; re‑seat the adapter, reload the program, check for I/O base or module faults.

  • Ethernet Link Down: Verify cable integrity, switch port status, IP settings, and BootP configuration.

  • Modbus No Response: Check RS‑485 wiring, baud rate, slave address, and terminating resistor.

  • No Program Execution: Ensure program is downloaded, RUN mode is active, and no fatal faults are present.

  • Overheating: Check ambient temperature, ventilation, and load; ensure no blockage of heat dissipation areas.
