22. INSTALLATION
22.1. Installation Precautions
Be sure to leave the installation work (rack mounting) to a
qualified 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 fire.
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)
specified by the manufacturer.
• 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.
• 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)."
