5. Installation Instructions

1. Handling: Do not bend sharply (min. radius 50 mm); avoid twisting or pulling hard

2. Routing: Keep away from high-voltage cables (>220 V) and heat sources (>70°C); use cable trays or conduits

3. Connector Care: Keep connectors clean and dry; avoid touching fiber end face with fingers

4. Connection: Align connector keyway, insert firmly, and tighten locking ring

5. Strain Relief: Secure cable at both ends to prevent tension on connectors

6. Testing: Power on system; check for “optical link OK” status on CNC; verify no communication alarms

6. Maintenance & Troubleshooting

• Maintenance: Inspect cable and connectors every 6 months; clean connectors with isopropyl alcohol and lint-free cloth if dirty

• Common Issues:

  • Link Alarm: Check connector seating, fiber end face cleanliness, cable breaks, or bend radius violations

  • Intermittent Errors: Look for loose connections, damaged sheath, or excessive vibration

  • No Signal: Verify correct cable type (multi-mode), compatible connectors, and system power

7. Safety Precautions

• Do not look directly into optical connectors—visible red light may damage eyes

• Disconnect power before installing or servicing

• Avoid installation in areas with corrosive gases or heavy oil mist

• Keep cable clear of moving parts to prevent damage
