UL guidelines
ThefollowingUnderwritersLaboratories(UL)guidelinespertaintotheinstallation
of the matrix switcher into a rack (figure 2-1).
1. Elevated operating ambient temperature—Ifinstalledinaclosedor
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)or113°F(45°C)(MAVPlus)ambienttemperature
(Tma) specified by Extron.
2. Reduced air flow—Installationoftheequipmentinarackshouldbesuch

3.
Mechanical loading—Mountingoftheequipmentintherackshouldbesuch
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
equipmentshouldbemaintained.Particularattentionshouldbegivento
supply connections other than direct connections to the branch circuit (e.g. use
of power strips.
