SECTION 2 – INSTALLATION
2.1 Introduction
This section contains unpacking and inspection procedures, installation information, and post-installation checks.
2.2 Continued Airworthiness
Maintenance of the JA77-005 is on condition only. Scheduled inspection and/or periodic maintenance of this unit is
not required.
2.3 Unpacking and Inspecting Equipment
Unpack the equipment carefully. Check for shipping damage and report any problems to the relevant carrier. Confirm
that the Authorized Release Certificate or Certificate of Conformance is included. Complete the on-line warranty card
from the Jupiter Avionics Corporation (JAC) website – www.jupiteravionics.com/warranty
2.3.1 Warranty
This product manufactured by JAC is warranted to be free of defects in workmanship or performance for 2 years from
the date of installation by an approved JAC dealer or agency. This warranty covers the cost of all materials and labour
to repair or replace the unit, but does not include the cost of transporting the defective unit to and from JAC or its
designated warranty repair centre, or of removing and replacing the defective unit in the aircraft. This warranty does
not cover failures due to abuse, misuse, accident, or unauthorized alteration or repairs.
THIS WARRANTY IS VOID IF THE PRODUCT IS NOT INSTALLED BY AN AUTHORIZED JAC DEALER. If the online warranty card is not completed, the product will be warranted from the date of manufacture.

JAC is the final arbiter concerning warranty issues.
2.4 Installation Procedures
CAUTION: The power input circuitry of the unit may be damaged if the installation does not conform to the
wiring instructions in this manual.
2.4.1 Installation Limitations
Those installing the JA77, on or in a specific type or class of aircraft, must determine that the aircraft installation
conditions are within standards. The JA77 may be installed only by following the applicable airworthiness
requirements.
2.4.2 Cabling and Wiring
All wire shall be selected in accordance with the original aircraft manufacturer’s maintenance instructions, or AC43.131B Change 1, Paragraphs 11-76 through 11-78. Unshielded wire types shall qualify to MIL-W-22759 as specified in
AC43.13-1B Change 1, Paragraphs 11-85, 11-86, and listed in Table 11-11. For shielded wire applications, use Tefzel
MIL-C-27500 shielded wire with tag ring or equivalent (for shield terminations) to make the most compact and easily
terminated interconnect. Follow the Connector Map and Interconnect in Appendix A of this manual.
Maintain wire segregation and route wiring in accordance with the original aircraft manufacturer’s maintenance
instructions.

Installation and Operating Manual
Unless otherwise noted, all wiring shall be a minimum of 22 AWG. Refer to the Interconnect drawing for additional
specifications. Check that the ground connection is clean and well secured.
2.4.3 Mechanical Installation
The JA77-005 can be mounted in any attitude and location with adequate space for the front panel and sufficient
clearance for the connector and wiring harness. It requires no direct cooling.
2.4.4 Legend Replacement
The JA77-005 illuminated legends are field replaceable. For further information, refer to the ‘Legend Replacement’
document in Appendix A of this manual.
2.5 Legend Text Selection using ProCS™
The JA77-005 has no required adjustments, but the configuration program ProCS™ can be used to customize the text
for each legend either at the time of ordering the unit, or if text changes are required after installation. The JA77-005
need not be connected to a computer to select the legend text.
For information on ordering customized legends, refer to the ProCS™ Ordering Instructions on the JAC website.
2.5.1 Front Panel Switches
The Front Panel Switches window is used to specify the text for each legend.

the legend will be left blank, and ‘New…’ which
allows the user to enter a completely new
legend of up to five characters. If a ‘new’
legend has been added, the option ‘Edit …’ is
added to the menu to enable changes to the
newly created label.
In the example shown here, the option ‘New…’ has been
selected. A pop-up ‘New Label’ window will appear,
allowing the user to create a customized legend – in this
case, JAC. The new legend name will now be shown in
the appropriate position on the faceplate representation
in the software program.

in multiple different configurations with only minimal changes.
The internal circuitry ensures that, although the legends are individually
illuminated, the illumination is consistent and uniform throughout all legends, and
never needs to be balanced. This means that if it is a requirement to change the
labelling due to damage or for a different project, there is no need for costly and
time-consuming illumination checks.
