3.0 Installation
3.1 Preparation
3.1.1 Careful consideration of the location of this and all other modules is
necessary. Some of the items to be considered in the design and
layout of the aircraft cabin include:
• Space
• Available power supply
• Environmental conditions (temperature, humidity, etc.)
• Length of cable runs
• Location of other aircraft systems (oxygen delivery)
3.1.2 The CTP-201-01-x shall be installed to conform to the standards
designated by the customer, installing agency, and existing
conditions as to the unit location and type of installation.
3.1.3 Mounting screws are required to secure the unit. Mounting points
will vary depending on the kit used. Refer to Section 7.0,
Reference Drawings, for mounting hole diameters and
configurations.
3.1.4 All headphone amplifiers and line level amplifiers should be located
no more than three (3) feet away from source equipment. Long
low-level audio runs may introduce noise into the audio signal.
3.1.5 The installing agency shall supply and fabricate all external cables
to the CTP-201-01-x. The length and routing of external cables
shall be carefully studied and planned before attempting installation
of the unit. Allow adequate space for installation of cable and
connectors. Mating connectors are the responsibility of the
installing agency. Correct pin assignments as outlined in Section
3.9 are the responsibility of the installing agency.
3.2 Unpacking and Inspection
3.2.1 Carefully open the packaging and remove the CTP-201-01-x.
Verify that all components have been included in the package per
the packing list. Inspect the unit for shipping damage.

Document # 540199, Rev B, 12/2004 Page 8 of 19
3.2.2 If damage has occurred during shipping, a claim should be filed
with Audio International WITHIN 24 hours and a Return Request
Authorization Number shall be obtained from AI by contacting the
Repair Department at 501.801.0640. Repackage the unit in its
original packaging materials and return it to AI following instructions
given by the AI representative. Refer to the front cover of this
manual for address. If no return is necessary, retain the packing
list and the packing materials for storage.
3.3 Cautions & Warnings
3.3.1 It is important to do a pin-to-pin power and ground check on all
connectors. Ensure that power and ground are applied only where
specified. Damage to the unit may result if power or ground is
applied to the wrong points.
3.3.2 DO NOT connect or disconnect the unit while power is applied.
3.3.3 DO NOT remove any factory-installed screws. Damage to the unit
may result and void any warranties.
3.3.4 DO NOT drop the unit or subject it to strong shock. The unit
contains glass parts that may break or crack.
3.3.5 DO NOT place foreign objects into openings. Contact with foreign
objects may result in dangerous voltage or electric shock.
3.3.6 DO NOT place near strong magnetic fields, radiators or other heat
sources.
3.3.7 DO NOT use this unit other than for its intended purpose. Doing so
might lead to electric shock or injury.
3.3.8 DO NOT use near water, moisture, or volatile sprays. Do not use
any type of solvent when cleaning (surface damage may occur).
3.3.9 ESD (Electro Static Discharge) guidelines shall be followed.

3.4 Wiring Requirements
3.4.1 Introduction
The installing agency shall supply and fabricate all external cables.
The length and routing of external cables shall be carefully studied
and planned before attempting installation of the equipment. Allow
adequate space for installation of cable and connectors. Avoid
sharp bends and placing cables near aircraft control cables.
Maintain a minimum clearance of three (3) inches from any control
cable. If wiring is run parallel to combustible fluid or oxygen lines,
maintain a separation of six (6) inches between the lines.
3.4.2 Power Wires
Audio International recommends that power and ground wires be
22 AWG minimum. The chassis shall be electrically bonded to the
airframe structure by a conductive mounting point with <0.1 Ω
resistance using <50 Ωimpedance cable. Aluminum wool, nylon
webbing impregnated with aluminum oxide abrasive or fiber bristle
brushes are the approved tools for removing anodized surfaces at
mounting point where the bonding wire is attached. Power and
Ground wires shall be in accordance with NEMA WC 27500 or
equivalent. Protect power wires with circuit breakers or fuses
located close to the electrical power source bus.
3.4.3 AI’s Proprietary RS-485 Data Bus
3.4.3.1 The CTP-201-01-x is designed to interface with other
Audio International equipment via AI’s proprietary
RS-485 serial data bus. The data bus shall be
implemented using a twisted shielded pair cable in
accordance with NEMA WC 27500 or equivalent. The
wire size for the conductors in this cable shall be 22
AWG, MINIMUM. The shield shall be connected
everywhere a shield pin is provided. Shield terminations
shall be made as close to the connector pin as possible.
3.4.3.2 Refer to AI document 650007 for RS-485 Serial Data Bus
design architecture.
