4. Installation Instructions

1. Cut off the main power supply completely before installation and maintenance.

2. Wear anti-static wristband and take anti-static measures to avoid static damage to the PCB board.

3. Confirm the part number A05B-2518-C202 matches the host equipment requirement.

4. Clean the cabinet slot to remove dust, metal filings and foreign debris.

5. Align the PCB board with the guide slot and insert it smoothly into position.

6. Tighten fixing screws evenly; do not over-tighten to prevent PCB deformation.

7. Connect power lines and signal lines strictly according to interface labels and wiring definition.

8. Recheck all connections, close the cabinet door, then perform power-on test run.

5. Operation Precautions

1. Use only rated standard power supply; unstable, overvoltage or undervoltage input is prohibited.

2. Hot plugging and unplugging the PCB board are strictly forbidden under powered-on status.

3. Do not use in environments with heavy dust, oil mist, corrosive gas, water splash and strong mechanical vibration.

4. Keep away from high-power inverters and strong electromagnetic interference sources during operation.

5. Do not disassemble, modify or replace internal circuits and components without professional authorization.

6. In case of system alarm, signal abnormality or abnormal heating, stop operation and cut off power immediately for inspection.
