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:
1. 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.
2. Reduced air flow — Install the equipment in the rack so that the equipment gets
adequate air flow for safe operation.
3. Mechanical loading — Mount the equipment in the rack so that uneven mechanical
loading does not create a hazardous condition.
4. 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.
5. 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).
