6. Installation Instructions

1. Power off the rack before inserting or removing the module.

2. Insert the module into the designated standard rack slot and secure it firmly.

3. Use shielded Ethernet cables for all external connections.

4. Route communication cables away from high-voltage power lines to avoid interference.

5. Ground cable shields at one end only to prevent ground loops.

7. Maintenance Notes

1. Periodically inspect module connections and surface condition.

2. Clean dust only with a dry cloth; do not use corrosive solvents.

3. If a fault alarm occurs, cease operation and inspect immediately.

4. Use only original Honeywell replacement parts.

8. Safety Requirements

1. All maintenance and wiring must be performed with the power off.

2. Do not operate beyond the specified temperature and voltage ranges.

3. Do not disassemble or modify the module’s internal components.

4. Avoid exposure to severe moisture, dust, or corrosive atmospheres.
