Installation Guidelines

• The PM 802F can be installed using DIN Rail (C-rail) or wall mounting.
• Ensure proper ventilation for the AC 800F to maintain the permissible ambient temperature range of 0 degC to 60 degC.
• Data protection for RAM is managed via battery backup; ensure the battery or battery module is correctly installed and monitored.
• When using redundancy, ensure a dedicated redundancy communications link is established through the second Ethernet module for synchronization.
