Technical Specifications

Installation Guidelines

• Mounting: Ensure the terminal is installed in a panel cutout that meets the manufacturer's specified dimensions to maintain the NEMA/IP seal integrity.
• Grounding: Always connect the chassis ground terminal to a low-impedance earth ground to mitigate EMI and protect against electrical surges.
• Wiring: Use shielded communication cables for the DH-485 port and keep them routed away from high-voltage power lines to prevent signal interference.
• Environment: Ensure adequate ventilation around the unit to maintain operating temperatures within the 0 to 55 deg C range.
• Safety: Power down the system before connecting or disconnecting any communication cables or power supply leads.
