Installation Guidelines

• Ensure the PLC is installed in a clean, dry, and adequately ventilated enclosure to maintain operating temperatures within the specified 0 to 60 degC range.
• Always disconnect the 24 VDC power supply before inserting or removing the module from the rack to prevent electrical arcing or damage to the backplane pins.
• Use shielded communication cables for RS232/RS485 connections and route them away from high-voltage power lines to minimize EMI interference.
• Maintain proper grounding of the chassis to the system common to ensure signal integrity and compliance with safety standards.
• Periodically verify the status of the internal battery to ensure data retention integrity during power cycles.
