Installation
Mounting the Switcher
The matrix switchers are housed in rack-mountable, metal enclosures with 19" rack
ears. The amount of vertical rack space required for each switcher is as follows:

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.
