6. Installation Instructions

1. Power Off

   • Disconnect all PLC and cabinet power before installation.

2. Connector Alignment

   • Locate the expansion port on the primary Quantum backplane (usually at one end).

   • Align the cable’s keyed connector with the port; do not force.

3. Secure Connection

   • Insert connector fully until latch clicks.

   • Repeat for secondary backplane port.

4. Cable Routing

   • Route cable away from high‑voltage cables (≥ 10 cm separation).

   • Avoid sharp bends and cable crushing.

5. Power Up & Verify

   • Restore power; check PLC LED status for backplane link OK.

7. Maintenance & Handling

• Inspection: Check connectors for wear, dirt, or bent pins every 6 months.

• Cleaning: Use dry, lint‑free cloth; avoid solvents.

• Replacement: Replace if jacket is damaged or communication errors occur.

8. Safety & EMC Guidelines

• Qualified Personnel Only: Install by authorized electricians.

• No Live Connection: Never connect/disconnect while powered.

• EMC: Keep shield continuous; ground at one end only to avoid loops.
