22. INSTALLATION
22.1. Installation Precautions
Be sure to leave the installation work (rack mounting) to a
qualiedinstaller.
(When rack mounting screws are supplied)
The supplied rack-mounting screws can be used for
the TOA equipment rack only. Do not use them for
other racks.
When installing the unit in a rack other than that of
TOA, be sure to use the screws with a diameter of
over 5 mm (0.2”) and length of over 12 mm (0.47”) to
mount the unit.
Failure to do so may cause the unit to fall, resulting in
personal injury.
(When rack mounting screws are not supplied)
Rack mounting screws are not supplied with the unit.
Be sure to use the screws with a diameter of over 5
mm (0.2”) and length of over 12 mm (0.47”) to mount
the unit.
Failure to do so may cause the unit to fall, resulting in
personal injury.
CAUTION
When installing the unit in an equipment rack, do not
block the ventilation slots on the unit’s both sides and
rear side. Doing so may cause heat to build up inside
theunitandresultinre.
CAUTION
22.2. Rack Mounting
• 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, consideration should be
given to installing the equipment in an environment compatible with the maximum ambient temperature (Tma)
speciedbythemanufacturer.
• ReducedAirFlow-Installationoftheequipmentinarackshouldbesuchthattheamountofairowrequired
for safe operation of the equipment is not compromised.
• MechanicalLoading-Mountingoftheequipmentintherackshouldbesuchthatahazardousconditionisnot
achieved due to uneven mechanical loading.
• 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.
• ReliableEarthing-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)."
