4. Installation and Troubleshooting 2 3 Site Selection Considerations The concentrator can be placed almost anywhere within your company including offices and computer rooms In general we recommend installation in a wiring closet The unit has been designed for rack mounting and comes with all the necessary hardware Location Requirements The area where you install the ONline System Concentrator must meet the following conditions a a Ventilation Temperature between 0 to 50 C 32 to 1222 F Relative humidity less than 9596 non condensing AC power source within 6 feet 2 meters Note that for installation to have true backup power two independent AC power sources are required The table or rack where the unit is installed should be level and not in direct sunlight or in an excessively dusty location The concentrator fan units draw air in through the front and bottom of the chassis and exhausts air out the back Make sure there are at least 6 inches 15 centimeters between the fan vents at the back of the unit and the nearest surface to allow adequate airflow for cooling This minimum distance is also required for access to the rear of the unit for maintenance The cable tray that comes standard with the concentrator helps prevent a tangle of cables at the front of the concentrator and also permits the required airflow to the unit Make sure the cable tray is installed below the unit correctly before installi
