Mounting environment – Install in a dry, ventilated, dust-free cabinet; avoid high temperature and humidity.
Wiring – Use industrial standard wires; ensure terminals are securely connected to prevent poor contact.
ESD protection – Wear an anti-static wrist strap during installation or maintenance.
Signal cable routing – Input/output signal cables should be routed separately from high-voltage power lines; shielded twisted-pair cable recommended.
Periodic inspection – Check terminal tightness and LED status to ensure stable input/output signals.
