The cabinet is supplied unassembled. Follow the included assembly diagram carefully. Typically, assembly involves:

1. Connecting the side panels to the top and bottom frames.
2. Attaching the rear panel.
3. Installing the 19-inch profile rails. These rails are variable in depth to accommodate different equipment sizes.

Before mounting, select a suitable location on a sturdy wall. The cabinet weighs approximately 33.3 pounds (15.1 kg) empty. When fully loaded with 60 kg of equipment, the total weight can exceed 75 kg. Ensure the wall structure can safely support this load.

1. Mark the drilling points on the wall using the wall mounting brackets as a template.
2. Drill holes and insert appropriate wall anchors (not always included, depending on wall type).
3. Secure the wall mounting brackets to the wall.
4. Carefully lift the assembled cabinet and hang it onto the secured wall brackets.
5. Ensure the cabinet is level and securely fastened to prevent accidental detachment.
