Equipment fans often produce insufficient flow to push air through the masses of data communication wiring at the rear of the enclosure. With an XDA placed on the exhaust side of the enclosure (the five high-static fans ensure positive air flow), the heat is moved out of the enclosure and into the room where it can be removed by the room air conditioning system. The Liebert XDA is also available as a factory-installed option on Liebert Foundation™ cabinets. 1.1 Features & Benefits • Improves extraction of heat from high heat density equipment cabinets • Permanently attached dual power cords to prevent accidental disconnection and increase up-time • Hot-Installable: No shutdown or removal of rack equipment is required • Serves the entire cabinet • Easily installed with common tools • No drilling required for most installations • Narrow enough to allow use of two units per rack for extreme heat density situations • Can be mounted on the outside or inside of the cabinet door • Consumes zero “U” of rack space • Can be used with or without a raised floor Keep these instructions for future reference. Please take a moment to complete the enclosed startup survey card. ! CAUTION Fans have moving parts that can cause personal injury. Keep clothing and fingers away from fan openings. System contains hazardous electrical voltage. Disconnect BOTH power cords before working within. Follow all local codes. 1 2.0 INSTALLATION The Liebert XDA can be attached to most equipment cabinet doors 60" tall or taller. The unit typically is installed on the outside of a cabinet’s rear door, generally used to discharge heat generated from the cabinet. If aisle space is insufficient for exterior mounting, and space is available inside the cabinet, the XDA may be installed on the inside of the door. 2.1 Equipment Inspection Immediately after receiving the shipment, remove the XDA and all components from the shipping carton and inspect each item for damage. Check to see that all parts are included: User Manual Unit with mounting angles attached Mounting bracket Mounting hardware: Screws - 10 Nuts -10 Cable ties - 10 Blocking material XDA as shipped - in foam packing material Power Cord Bushing 2.2 Pre-Installation Considerations • Verify that the XDA unit voltage matches the available utility power. The nameplate with this information is located on the top of the unit. • Note the XDA’s appearance: the front of the unit bears the Liebert logo (or label) and long, horizontal slots across the fans; the rear of the unit has smaller slots over the fans. • The XDA is attached to the cabinet door using screws and nuts. In most cases, existing holes in perforated cabinet doors can be used to mount the XDA. Horizontal slots in the XDA mounting angles provide easy alignment with existing holes in the cabinet door. • If the desired mounting position places mounting holes over the solid portion of the door, mark and drill holes as needed in the solid portion of the door, using a 3/16" drill bit. NOTE Check for interference with the cabinet’s handle/latch. If the handle swings toward the center rather than toward the outside of the door, it may limit positioning options for the XDA. 2 2.2.1 Required Tools • Phillips screwdriver • Pliers • Scissors 2.3 Mounting the XDA on the Ext...
