Installation Guidelines

• Ensure the terminal is mounted in a panel or enclosure that provides adequate protection and ventilation to maintain operating temperatures below 50 degC.
• Verify that the AC power source is within the specified 85-264 VAC range before connection.
• Use shielded communication cables for DH-485 and RS-232 connections to minimize electromagnetic interference (EMI).
• Ensure proper grounding of the terminal chassis to the enclosure ground bus to prevent electrical noise issues.
• Power down the unit before performing any maintenance, such as replacing the display backlight or accessing internal components.
• Avoid installing the unit in areas with high vibration or extreme moisture unless the enclosure rating is sufficient for the environment.
