Installation Guidelines

• Ensure the chassis is mounted on a flat, stable surface within an industrial enclosure to prevent mechanical stress.
• Maintain adequate clearance around the chassis to allow for proper airflow and cooling, adhering to the specified operating temperature range.
• Always disconnect power before installing or removing modules from the chassis backplane to prevent electrical damage.
• Ensure the chassis is properly grounded in accordance with local electrical codes to minimize EMI and protect against surges.
• Verify that all modules are fully seated and secured using the integrated module locking mechanisms.
