Installation Guidelines

• Ensure the panel cutout is prepared according to the manufacturer's mounting template to maintain the integrity of the enclosure seal.
• Verify that the DC power supply voltage matches the requirements of the terminal before connection.
• Use shielded communication cables for RS-232/RS-485 connections to minimize electromagnetic interference (EMI) in industrial environments.
• Always power down the unit before connecting or disconnecting communication cables or power leads.
• Ensure proper grounding of the terminal chassis to a common earth point to prevent ground loops and electrical noise.
