13. INSTALLATION
13.1. Installation Precautions
Be sure to leave the installation work (rack mounting) to a
qualified installer.
Rack
CAUTION
Power amplifier
Blank panel
DP-SP3
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.
• 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)."
• Température ambiante élevée - si l’appareil est installé dans un bâti fermé ou en même temps que d’autres
appareils, la température à l’intérieur risque de devenir supérieure à la température ambiante. Par conséquent,
veiller à installer l’équipement dans un environnement compatible à la température ambiante maximum
spécifiée par le fabricant.
• Débit d’air réduit - L’installation de l’équipement en bâti ne doit pas compromettre le débit d’air nécessaire à
une utilisation sûre de l’équipement.
• Charge mécanique - Le montage de l’équipement en bâti ne doit pas entraîner de danger dû à une surcharge
mécanique inégale.
• Surcharge du circuit - rester vigilant lors de la connexion de l’équipement au circuit d’alimentation et
aux conséquences d’une surcharge des circuits sur la protection contre les surintensités et les câbles
d’alimentation.
Tenir compte des indications de la plaque nominale de l’appareil.
• Sécurité de la mise à la terre. Veiller à toujours garantir l’intégrité de la prise de mise à la terre. Faire
particulièrement attention aux connexions d’alimentation en dehors des branchements directs au circuit de
dérivation (par exemple à l’aide de multiprises).

13.2. Mounting in a Rack
CAUTION
(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.

14.2. Removable Terminal Plug Connection
Notes
• Avoid soldering stranded or shielded cable, as contact resistance may increase when the cable is tightened
and the solder is crushed, possibly resulting in an excessive rise in joint temperatures.
• When connecting 2 cables or a shielded cable to a single terminal, use a ferrule terminal with an insulation
sleeve to crimp the cables because such cable conductors could become loose.
