UL guidelines
The following Underwriters Laboratories (UL) guidelines pertain to the installation
of the matrix switcher into a rack (figure 2-1).
1. Elevated operating ambient temperature — If installed in a closed or
multi-unit rack assembly, the operating ambient temperature of the rack
environment may be greater than room ambient. Therefore, consider
installing the equipment in an environment compatible with the maximum
122 °F (50 °C) (CrossPoint) or 113 °F (45 °C) (MAV Plus) ambient temperature
(Tma) specified by Extron.
2. Reduced air flow — Installation of the equipment in a rack should be such
that the amount of air flow required for safe operation of the equipment is not
compromised.
3. Mechanical loading — Mounting of the equipment in the rack should be such
that a hazardous condition is not achieved due to uneven mechanical loading.
4. Circuit overloading — Consideration should be given to the connection of the
equipment to the supply circuit and the effect that overloading of the circuits
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) — Reliable earthing of rack-mounted
equipment should be maintained. Particular attention should be given to
supply connections other than direct connections to the branch circuit (e.g. use
of power strips.
