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).
