Installation Guidelines

• Handling: Ensure the processor and adapter are powered down before installation to prevent electrical damage to the backplane connectors.
• Battery: Verify the state of the backup battery upon installation. Replace the battery periodically according to the maintenance schedule to ensure the TOD clock remains operational during power outages.
• Alignment: Carefully align the adapter with the Momentum processor interface and secure it firmly to ensure reliable communication signal path.
• Network Wiring: If utilizing the Modbus Plus port, ensure the network is correctly terminated with appropriate resistors at both ends of the trunk.
• Environment: Keep the installation site free from extreme heat, moisture, and conductive contaminants to protect internal electronic circuits.
