Rack Mounting
UL Guidelines for Rack Mounting
The following Underwriters Laboratories (UL) guidelines are relevant to the safe
installation of this product 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. Appropriate consideration of the equipment nameplate ratings should be
used 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).
