UL Guidelines
The following Underwriters Laboratories (UL) guidelines pertain to the installation of the
matrix switcher into a rack.
• 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.
• 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.
• Mechanical loading — Mounting of the equipment in the rack should be such that a
hazardous condition is not achieved due to uneven mechanical loading.
• 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.
• 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 (such as the use of power strips).
Mounting Instructions
1. Insert the unit into the rack, aligning the mounting bracket holes with those in the rack
(see figure 108).
2. Secure the switcher to the rack using the supplied bolts.
