6. Installation Notes & Maintenance Best Practices
   Pre-installation considerations
   Confirm the VersaMax rack capacity and the backplane revision to ensure compatibility with the ALG620-GD. Verify sensor wiring topology (two-wire RTD loops, shielded cabling, and proper terminations) and ensure calibration references are ready. Plan for sensor drift compensation in software and align hardware ranges to sensor specs. Document the channel mappings and sensor types to ease future upgrades and audits.

Maintenance best practices
Schedule regular health checks of RTD inputs, verify resistance readings against known references, and monitor channel diagnostics for drift, open circuits, or shorted sensors. Keep spare ALG620-GD modules and commonly used RTD sensors in inventory to minimize downtime. Maintain thorough records of RTD types, calibration data, and firmware baselines to support audits and lifecycle management.
