Installation Guidelines

• Mount the CPU unit securely onto the dedicated CS1 backplane inside a protective, dust-free industrial enclosure.
• Always shut off the main system power supply before mounting or removing the CPU module.
• Ensure reliable grounding of the PLC rack to a dedicated ground point of 100 ohms or less.
• Separate all low-voltage communication cables (RS-232C, peripheral) from high-voltage AC power lines to avoid electromagnetic interference.
• Maintain adequate physical clearance above and below the CPU unit to guarantee proper air convection and thermal dissipation.

Compliance and Certifications
