UL guidelines for rack mounting
ThefollowingUnderwritersLaboratories(UL)guidelinespertaintotheinstallation
of an SW8/12 VGA Ars switcher unit onto a rack.
1
. Elevated operating ambient—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ambienttemperaturespecied
by Extron (Tma = +32to+122°F[0to+50°C]).
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 (such as
the use of power strips).
