7. Installation Instructions

1. Power Off: Disable power to all connected modules before installation.

2. Align Connectors: Match the male RJ45 key with the MB+ master port on the first module.

3. Insert Firmly: Push until the latch clicks, confirming secure shield contact.

4. Connect Second End: Repeat for the MB+ port on the second module.

5. Verify Connection: Ensure both connectors are fully seated and locked.

6. Power On: Restore power and verify MB+ network status via PLC software.

8. Maintenance

• Quarterly Inspection: Check RJ45 connectors for wear, dirt, or bent pins.

• Cable Care: Avoid heavy stress, sharp bends, or crushing.

• Shield Integrity: Verify continuity; follow MB+ grounding rules (avoid both‑end grounding).

• Replacement: Replace if insulation is damaged or connectors show corrosion.

9. Safety Precautions

• Qualified Personnel: Installation and service by qualified technical staff only.

• Power Disconnection: Always disconnect power before connecting/disconnecting.

• Indoor Use Only: For indoor industrial environments; avoid sunlight and moisture.

• Damage Check: Do not use if insulation or connectors are damaged.

• Disposal: Dispose per local electronic waste regulations.

10. Troubleshooting

No MB+ Communication

• Confirm both RJ45 latches are fully engaged.

• Verify MB+ network power and termination (120 Ω at trunk ends).

• Check unique MB+ addresses and correct master/slave configuration.

Intermittent Communication

• Inspect for loose latches or bent pins.

• Check for excessive vibration or cable movement.

• Ensure proper shield connection at both ends.
