Installation and Maintenance
Insert the module into the designated rack slot and lock it firmly before connecting communication cables and power lines. Check wiring connection status and terminal tightness to avoid poor contact. Keep the installation area dry and well ventilated, and prevent dust and corrosive substances from accumulating on the surface. Perform regular routine inspections on port status and communication signals. When maintenance or replacement is needed, cut off the power supply first to guarantee operational safety. The module has a solid mechanical structure and requires no frequent calibration, which effectively reduces daily maintenance workload and system downtime.
