UL Guidelines for Rack Mounting
The following Underwriters Laboratories (UL) guidelines are relevant to the safe installation of the XPA U 4004 FX
amplifier in a rack:
CAUTION:
•
Elevated operating ambient temperature — If the unit is installed in a closed or multi-unit rack
assembly, the operating ambient temperature of the rack environment may be greater than room
ambient temperature. Therefore, install the equipment in an environment compatible with the maximum
ambient temperature (Tma: +122°F, +50°C) specified by Extron.
•
Reduced air flow — Install the equipment in the rack so that the equipment gets adequate air flow for
safe operation.Mechanical loading — Mount the equipment in the rack so that uneven mechanical
loading does not create a hazardous condition.
•
Mechanical loading — Mount the equipment in the rack so that uneven mechanical loading does not
create a hazardous condition.
•
Circuit overloading — Connect the equipment to the supply circuit and consider the effect that circuit
overloading might have on overcurrent protection and supply wiring. Consider the 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).
