Table Top Installation Requirements

For table top or shelf mount installation of the ONline System Concentrator you must make sure the table or shelf can support 100 pounds (45 kg) for a fully loaded 17-slot concentrator. (The concentrator itself, fully loaded and with cable tray, weighs almost 75 pounds/34 kilograms.) The table/shelf also must be less than 6 feet (2 meters) from the nearest AC outlet.

To ensure proper airflow to the unit, you should leave at least 1.75" (4.45cm) of space below the concentrator (provided by the installed rubber feet) and by installing the cable tray below the concentrator.
