UL Guidelines for Rack Mounting

The following Underwriters Laboratories (UL) guidelines pertain to the installation of the AVT into a rack:

•Elevated operating ambient temperature — If the equipment is installed in a closed or multi-unit rack assembly, the operating ambient temperature of the rack environment may be greater than room ambient. Therefore, consider installing the equipment in an environment compatible with the maximum ambient temperature (Tma) specified by the manufacturer.

•Reduced air flow — Install the equipment in the rack so that the amount of air flow required for safe operation of the equipment is not compromised.

•Mechanical loading — Mount the equipment in the rack so that uneven mechanical loading does not create a hazardous condition.

•Circuit overloading — When connecting the equipment to the supply circuit, consider the effect that circuit overloading might have on overcurrent protection and supply wiring. Consider equipment nameplate ratings when addressing this concern.

•Reliable earthing (grounding) — Maintain reliable grounding of rack-mounted equipment. Pay particular attention to supply connections other than direct connections to the branch circuit (such as the use of power strips).

Rack Mounting Procedure

The AVT matrix switchers are housed in rack-mountable metal enclosures with mounting flanges for standard 19-inch racks. If desired, rack mount the AVT 200HD as follows:

1.Attach the included mounting brackets to the unit using eight of the machine screws provided with the mounting kit.

2.Insert the tuner into the rack, aligning the holes in the mounting brackets with those in the rack. Use four provided machine screws to attach the brackets to the rack.
