Rack Mounting
UL Guidelines for Rack Mounting
The following Underwriters Laboratories (UL) guidelines are relevant to the safe installation of
these products in a rack:
Elevated operating ambient temperature — If the units are 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.
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).
Rack Mounting Procedure
To mount the unit on a rack shelf, follow the instructions provided with the shelf accessories.
