7.1.1. Setting space
For maintenance works, allow much space between the wall and Equipment rack.
7. INSTALLATION
The N-8000MI can be installed in any of two ways: Equipment rack mounting and Desk-top installation.
7.1. Equipment Rack Mounting
A) 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.
B) 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.
C) Mechanical Loading - Mounting of the equipment in the rack should be such that a hazardous condition is
not achieved due to uneven mechanical loading.
D) 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.
E) 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).”
A) 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 spéciée par le fabricant.
B) 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.
C) Charge mécanique - Le montage de l’équipement en bâti ne doit pas entraîner de danger dû à une surcharge
mécanique inégale.
D) 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.
E) 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).
The N-8000MI can be mounted on the CR-273 or CR-413 or standard EIA 19” Equipment rack.
