UL requirements
The following Underwriters Laboratories (UL) requirements pertain to the
installation of the MVX Plus 128 VGA A into a rack.
1. Elevated operating ambient temperature — If the equipment 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 MVX Plus 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 (e.g. use of power strips).
Mounting instructions
The matrix switcher is housed in rack-mountable, 2U high metal enclosure with
mounting flanges for a standard 19" rack. If desired, rack mount the switcher as
follows:
1 . Insert the switcher into the rack, aligning the holes in the mounting bracket
with those in the rack.
2 . Secure the switcher to the rack using the supplied bolts.
