5. INSTALLATION Of The AUDIO INTeRfACe UNIT, C/O INTeRfACe
UNIT AND TeLePhONe INTeRfACe UNIT
The N-8000AF/8000CO/8000AL can be installed in any of three ways: (1) equipment rack mounting, (2) wall
mounting, and (3) desk-top installation.
5.1. 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)."
The N-8000AF/8000CO/8000AL can be mounted on the CR -273, CR -413, or standard EIA 19" Equipment
rack.
For the CR -273 and CR -413 Equipment rack assembly, read the installation manual supplied with the rack.
Note
When installing the N-8000AF/8000CO/8000AL, lay the equipment rack down face-up to do installation work
safely.
5.1.1. Setting space
For maintenance works, allow much space between the wall and Equipment rack.
