6、 Installation and maintenance
Installation specifications:
Before installation, it is necessary to confirm that the power supply voltage matches the equipment specifications. The rack installation position should be far away from strong electromagnetic interference sources (such as frequency converters, high-power motors) and heat sources (such as heaters, radiators), and at least 10cm of heat dissipation space should be reserved.
Using 35mm DIN rail to fix the rack, ensuring a secure installation without shaking; When wiring, it is necessary to distinguish between power and signal cables to avoid parallel laying of strong and weak electrical cables. The wiring terminals should be tightened to prevent poor contact.
Programming communication cables require the use of shielded cables, with the shielding layer grounded at one end to reduce communication interference; After installation, insulation testing is required to ensure that the circuit insulation resistance meets industrial safety standards.
Daily maintenance:
Regularly (monthly) check the status of power indicator lights and communication indicator lights, view module fault logs through programming software, and promptly identify potential problems; Clean the surface dust of racks and modules quarterly, using dry compressed air or soft bristled brushes to avoid dust accumulation affecting heat dissipation.
Regularly (every six months) check the tightness of the wiring terminals, especially the power and communication cable joints, to prevent loosening caused by vibration; Backup user programs and system configurations, store them on secure media to prevent program loss.
When handling faults, priority should be given to locating the fault point through module indicator lights and diagnostic logs. Before replacing the module, the power supply should be disconnected and anti-static measures should be taken; If it involves program modification, the original program needs to be backed up first, and after modification, offline testing should be conducted before going online for operation.
