  • ESD protection for communication lines in high-noise industrial environments

  • Compatible with Modicon PLCs, I/O modules, and HMIs in Momentum/Quantum/Premium systems

6. Installation Steps

  1. Power off the entire Modbus Plus network before installation.

  2. Mount the 170XTS02300 on a DIN rail or panel near the T-connector/terminator.

  3. Prepare the communication cable: Strip 3 cm of outer jacket, expose shield (do not trim strands).

  4. Open the earthing clamp: Loosen the screw, lift the top plate.

  5. Insert the cable shield into the clamp: Ensure full contact between shield strands and tinned copper plate.

  6. Tighten the screw to 0.5–0.8 Nm (do not over-tighten).

  7. Connect the cable’s RJ45 plug to the T-connector/terminator.

  8. Run a ground wire from the 170XTS02300’s earth terminal to the cabinet’s protective earth (PE) bus.

  9. Verify continuity with a multimeter (shield to PE resistance ≤ 5 mΩ).

7. Maintenance

  • Inspect the clamp periodically for loose screws, corrosion, or damaged contacts.

  • Ensure shield strands remain securely gripped (no fraying or breakage).

  • Check the PE connection for tightness and corrosion.

  • Keep the housing clean and dry; avoid conductive dust buildup.

  • Replace the unit if the housing is cracked or contacts are damaged.

8. Safety Instructions

  • Installation and service must be performed by qualified electricians.

  • Disconnect all power before wiring or modifying the network.

  • Ensure the cabinet’s PE bus is properly grounded per local electrical codes.

  • Do not use beyond rated voltage, current, or temperature limits.

  • Avoid exposure to liquids, corrosive gases, or explosive atmospheres.

9. Troubleshooting

  • High noise / intermittent communication errors:

    • Check shield grounding (ensure 170XTS02300 is properly connected to PE).

    • Verify clamp screw torque (0.5–0.8 Nm).

    • Inspect shield strands for breaks or poor contact.

  • ESD events / system resets:

    • Confirm all cable shields are grounded at both ends (where required).

    • Check for floating shields (no ground connection).

    • Ensure the earthing clamp is mounted close to the T-connector/terminator.
