Installation Guidelines

• Mounting: Secure the rack horizontally within the enclosure using all provided mounting points to ensure vibration resistance and long-term mechanical stability.
• Redundancy Setup: Install the primary and secondary CPMs into the designated redundant slots; ensure both modules are fully seated to engage the backplane pins correctly.
• Cooling: Maintain a minimum clearance around the rack assembly to facilitate proper airflow, as redundant controller configurations generate localized thermal loads.
• Grounding: Connect the rack chassis to the main system common ground to ensure optimal electromagnetic compatibility (EMC) and protection against transient interference.
• Cabling: Utilize dedicated cable management to keep communication and power wiring organized, preventing physical stress on the backplane connectors.
