For Use in Non-Certified Aircraft
When installing the xVue Touch System, the following cabling requirements must be met:
(1) Wire size for the KSD 100EXP, KCP 100EXP, KG 71EXP, and KMG 7010/MD32 and KDC 100EXP:
(a) For power and signaling lines, use 22 AWG minimum

3.10 Electrical Bonding Considerations
All rack mount/remote mount units must be electrically bonded to the airframe. This is accomplished by
ensuring that the mating surfaces between the component mounting tray (or component mounting feet
if a tray is not used) provides a low impedance electrical path.
The mating surfaces must be free of all paint and other non-conductive elements and should be
burnished to ensure a good bond. If the airplane mating surface is not conductive, a bonding strap of at
least 1/4inch wide (preferably 1/2inch wide) tin coated copper braid should be used between the
component mounting tray (or component itself if a tray is not used) and the nearest airframe grounding
point.
Electrical bonding begins with the equipment attach point(s) such as the mounting rack or the instrument
panel. Ensure good metal-to-metal bonding as brackets and shelves are assembled and installed. The
electrical bond between the following shall be less than or equal to 2.5 milliohms:
KSD 100EXP:
(1) KSD 100EXP and the airplane instrument panel
(2) KSD 100EXP and the mating backshell
KCP 100EXP:
(3) KCP 100EXP and the airplane instrument panel
(4) KCP 100EXP and the mating backshell
KG 71EXP:
(5) KG 71EXP and the airplane local structure
(6) KG 71EXP and the mating backshell
KMG 7010/MD32 and KDC 100EXP:
(7) KMG 7010/MD32 and KDC 100EXP and the airplane local structure
(8) KMG 7010//MD32 and KDC 100EXP and the mating backshell
KTP 73:
(9) KTP 73 and the airplane ground
Compliance should be verified using a calibrated milliohm meter. Any paint removed from the instrument
panel to meet the bonding requirement should have a corrosion resistant protective coating applied that
meets the specification found in AC 43.13-1B.
WHEN TERMINATING SHIELD GROUNDS TO THE OUTSIDE OF xVue Touch SYSTEM BACKSHELLS, IT IS RECOMMENDED TO APPLY THE SOLDER
SLEEVE AS SHOWN IN THIS FIGURE. THIS IS TO PREVENT OVERCROWDING INSIDE THE BACKSHELL WHILE STILL PROVIDING AN ACCEPTABLE
METHOD OF GROUNDING THE SHIELD.
