Installation Guidelines

Power Isolation: Always isolate and switch off the system power supply before inserting, removing, or performing maintenance on the interface module.
Mounting: Slide the module carefully into the designated chassis slot, ensuring the backplane connectors align correctly before securing any retention screws.
Cabling and Shielding: Use verified, shielded twisted-pair cables for all external I/O link connections to minimize susceptibility to electromagnetic interference (EMI).
Thermal Management: Maintain adequate clearance around the cabinet enclosure to permit natural or forced convection cooling, preventing localized heat buildup.
