4. Installation Instructions

1. Completely cut off the main power supply of CNC equipment before installation and maintenance.

2. Take effective anti-static measures to avoid static damage to the circuit board.

3. Confirm the part number and model match the requirement of the host equipment.

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

5. Align the PCB board with the guide slot, insert smoothly into the fixed position.

6. Tighten fixing screws evenly; over-tightening is forbidden to prevent PCB deformation.

7. Connect power lines and signal lines strictly in accordance with interface labels.

8. Recheck all wiring and assembly, close cabinet door, then perform power-on test run.

5. Operation Precautions

1. Only use rated standard power supply; unstable, overvoltage or undervoltage input is prohibited.

2. Hot plugging and unplugging the circuit board are strictly forbidden under powered-on state.

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

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

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

6. Power off immediately for inspection once system alarm, signal abnormality or overheating occurs.
