Installation
2.1 INTRODUCTION
This section provides installation information for the CP-2500. Installation must be made by qualified
personnel, in conformance with applicable government regulations. The information furnished is for
convenience only.
Tolerances (unless otherwise indicated):
ANGLES ARE ± 0.5°
0.00 TWO PLACE DECIMALS ARE ± 0.02
0.000 THREE PLACE DECIMALS ARE ± 0.010
2.2 UNPACKING AND INSPECTING
Carefully unpack the unit and note any damage to shipping containers or equipment. Visually inspect
each component for evidence of damage. Compare the equipment received with that noted on the packing
list. Report immediately any missing items or evidence of damage to the carrier making the delivery. To
justify a claim, retain the original shipping container and all packing materials.
Every effort should be made to retain the original shipping containers for storage. If the original
containers are not available, a separate cardboard container should be prepared that is large enough to
accommodate sufficient packing material to prevent movement.
2.2.1 Transport and Storage Considerations
Transport of the CP-2500 should be done in accordance with standard procedures, i.e. hand carried or
transported in the original container.
Storage of the CP-2500 must be consistent with industry standards for avionics equipment and will
perform satisfactorily after periods of storage up to 18 months. The ambient temperature of the storage
area should not fall below -55° C (-67° F) or rise above +85° (+185° F).
2.3 INSTALLATION PROCEDURES
1. The installer must consider the following prior to installation. Specific procedures for installation of
the CP-2500 are detailed in their respective paragraphs below.
•The installer must obtain installation approval (i.e. Supplemental Type Certification or form 337
if the installer has prior approved data).
•Follow the acceptable avionics installation practices in FAA Advisory Circulars AC 43.13-1B and
AC 43.13-2B or later revision of these documents.
•Installers are responsible for obtaining installation hardware (i.e. supporting plates, etc). An
Installation kit is shipped with the unit. Refer to the general information section for a list of parts
included with the kit.
•It is the responsibility of the equipment installer to determine that the required aircraft-viewing
envelope is within the specified display viewing envelope(s).
•It is recommended that the aircraft battery be disconnected before performing installation
procedure.

CP-2500
Installation Manual
Page 2-2 Installation 0040-17251-01
March 15, 2018 Revision D
•Tighten all screws to snug (i.e. only such torque that can be applied by hand) unless specific
torque instructions are given.
•After installation, refer to the Installation Checkout section for ground testing procedures.
2. Electrical equipment chassis and shield/ground terminations must be electrically bonded to the
aircraft's main structure (metallic aircraft) or instrument panel (composite aircraft). Compliance of
the electrical bonding should be verified by inspection using a calibrated milliohm meter or an
equivalent OEM procedure.
•The electrical bond should achieve direct current (DC) resistance less than or equal to 2.5 mto
structure local to where the equipment is mounted for metallic aircraft or tube and fabric aircraft.
•The electrical bond should achieve direct current (DC) resistance less than or equal to 5.0 mto
the instrument panel for composite aircraft.
2.3.1 Location
The CP-2500 should be mounted in the instrument panel slightly below and in close proximity with the
pilot's normal line of view, with the controls within easy reach. In selecting a location, consider the
following:
1. The CP-2500 should be accessible for inspection, maintenance, or removal and free from instrument
panel structural flexure and excessive vibration or heat.
2. Compare the space requirements of the CP-2500 with the installation area being considered.
•The CP-2500 with part numbers 9080-17250-01 & -02 mount in a 2 ¼ inch standard round
instrument hole. Refer to Figure 2-1. Outline dimensions are located in Figure 2-2.
•The CP-2500 with part number 9080-17250-12 mounts in a 3 1/8 inch standard round
instrument hole. Refer to Figure 2-1. Outline dimensions are located in Figure 2-3.
