Installation Of The Multi Interface Unit; Equipment Rack Mounting; Setting Space; Caution When Installing The Unit - Aiphone AN-8000 Operating Instructions Manual

2. INSTALLATION OF THE MULTI INTERFACE UNIT

The AN-8000MI can be installed in any of three ways: (1) equipment rack mounting, (2) wall mounting, and (3)
desk-top installation.

2.1. 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 AN-8000MI can be mounted on the CR -273 or 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 AN-8000MI, lay the equipment rack down face-up to do installation work safely.

2.1.1. Setting space

For maintenance works, allow much space between the
wall and Equipment rack.

2.1.2. Caution when installing the unit

CAUTION
Do not stack up 3 units or more. If 2 or more units
are mounted in the Equipment rack, be sure to
mount the perforated panel of 1 U size (PF-013B)
or more above and below every 2 units.
Do not block the ventilation slots. Doing so may cause heat to build up inside
the unit and result in fire.
