5. Installation & Operation Instructions

5.1 Pre-installation Inspection

1. Check module shell for cracks, deformation; confirm golden fingers free of oxidation, dust and corrosion;

2. Verify cabinet stable 24VDC power supply and reliable protective grounding;

3. Confirm matching backplane, FBM modules and bus cables for redundant system configuration.

5.2 Cabinet Installation Steps

1. Cut off total cabinet power, hang power-off warning signs to prevent live operation;

2. Install two P0916DJ modules side by side on standard DIN rail, lock bottom buckles;

3. Connect dual redundant 24VDC power terminals for both master and standby modules, tighten wiring screws;

4. Plug Ethernet, ControlNet redundant bus and RS232 debugging cables into corresponding rear interfaces, lock fixing nuts;

5. Connect fieldbus extension cables between P0916DJ and FBM modules / FEM100 expanders;

6. Restore power, log in DCS upper computer to verify redundant master-standby synchronization and bus communication status, test manual/auto switching function.

5.3 Daily Maintenance Rules

1. Full visual inspection every 3 months: Check heat dissipation, interface tightness and dust accumulation;

2. Forbid hot swapping modules and communication cables; all disassembly work must be powered off;

3. Clean golden fingers with anti-static soft cloth when dusty; alcohol and corrosive cleaners are prohibited;

4. Replace module immediately if communication disconnection, abnormal heating, synchronization failure or frequent alarms occur.

6. Safety Warning

• Strictly prohibit live plugging/unplugging modules and signal cables, which may burn internal chips and cause system bus collapse;

• Complete reliable cabinet grounding during installation to suppress electromagnetic interference and avoid calculation deviation;

• Do not install in flammable explosive gas, strong acid/alkali splash environment without sealed protective cabinet;

• Separate low-voltage signal wiring and high-voltage power cables by over 15cm to avoid induced signal disturbance.
