UL Rack Mounting Guidelines
The following Underwriters Laboratories (UL) guidelines pertain to the safe installation of the
SMP 111 in a rack.
1. Elevated operating ambient temperature — If installed in a closed or multi‑unit rack
assembly, the operating ambient temperature of the rack environment can be greater
than room ambient temperature. Therefore, install the unit 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 a rack so that the amount of air flow
required for safe operation of the equipment is not compromised.
3. Mechanical loading — Mount the equipment in the rack so that a hazardous
condition is not achieved due to uneven mechanical loading.
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 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 (for example: use of power strips).
