5.2 Safe Operation and Maintenance Specifications
- Installation and wiring must be performed by professional personnel. Before operation, disconnect the system power supply and confirm no voltage exists before disassembly and assembly to avoid electric shock or module damage.
- Signal wiring must match terminal specifications; shielded cables should be used for analog signals with the shielding layer grounded at a single point to prevent measurement errors caused by interference.
- Regularly check the module status indicator lights, terminal tightness and channel accuracy. In case of drift or faults, calibrate or replace the module in a timely manner.
