Mount the unit on the cabinet cutout and ensure the sealing part is installed properly to keep the protection performance. Use shielded cables for communication wiring and keep power cables apart from signal cables. Check power polarity and circuit protection components before powering on. Complete project editing and parameter setting via supporting configuration software. Clean the touch screen regularly with mild cleaning agents and avoid corrosive substances. Inspect connecting cables and terminals periodically to fix loose or damaged parts timely. Store project files in external devices for backup and update firmware as required. Take anti-static measures during installation and maintenance, and keep the device away from intense vibration and direct sunlight.
