How to install Eaton Tripp Lite Series SmartRack Industrial Enclosure

• Plan the installation location: Choose a solid, vibration-free wall with access to electrical power and data connections. Verify wall studs or solid backing capable of supporting the weight of an empty enclosure plus mounted equipment.
• Prepare mounting hardware: Use appropriate wall anchors or commercial-grade screws rated for your wall material. Confirm that fasteners meet or exceed the weight and load requirements specified for the enclosure.
• Attach mounting brackets or chassis to the wall: With assistance, position the enclosure and secure it to the wall using the included mounting points. Ensure the unit is level and firmly anchored before proceeding.
• Install rack-mount equipment: Attach 19" rack-mount rails and install switches, patch panels, PDUs, and other equipment according to standard 19" mounting procedures. Leave space for rear cabling and ventilation as needed.
• Route cables and secure rear access: Run power, network, and other cables through the enclosure’s rear openings. Use cable management accessories to keep cables neatly organized and away from fans or vents, if present. Close the hinged back panel as required for maintenance access, then lock the door to secure the enclosure.
• Verify operation and safety: Power on equipment, confirm network connectivity, and verify that doors clear all mounted gear when opened. Check for any obstructions and ensure proper airflow paths to prevent overheating.
