(b) KANDU receptacle A3J2 is MIL-DTL-38999/20FC4SN, series Ill, flange mount
receptacle, insert 13-4, normal keying, with four socket-type contacts of size 16 AWG.
Mates with D38999/26FC4PN for power output.
(c) KANDU receptacle A3J3 is MIL-DTL-38
999/20FG35PN, series III, flange mount
receptacle, insert 21-35, normal keying, with 79 pin-type contacts of size 22 AWG.
Mates with D38999/26FG35SN for control interface.
(d) KANDU receptacle A3J4 is TVPOORGQF-21-75P (Amph
enol) or equivalent. Mates
with TV06RQF-21-75S (Amphenol) or equivalent for Ethernet interface.
(e) Maximum round trip wiring interconnection resistance between KANDU A3J2 and
OAE-TMA A5J2 m
ust not exceed 0.684 ohms (considering 20 AWG wire cables of
length 32.8 feet (10 m)).
(f) KANDU bonding to the aircraft must be achieved through the mounting structure
(fasteners) and KANDU A3J1-A.
The bulkhead interfac
e is as follows:
(g) It is recommended to use MIL-DTL-38999 series III, insert 19-3
5, normal keying with 66
contacts as KANDU bulkhead control connector for KANDU inter-wiring to MODMAN if
KANDU is installed in an unpressurized location inside aircraft.
(h) It is recommended to use MIL-DTL-38999 series III, insert 19-3
5, normal keying with 66
contacts as KANDU bulkhead control connector for KANDU inter-wiring to KRFU and
OAE-TMA if KANDU is installed in pressurized location inside aircraft.
(i) It is recommended to use MIL-DTL-38999 series III, insert 17-8, normal keying with eight
contacts as KANDU bu
lkhead power connector if 115 VAC power is not provisioned in
unpressurized location of aircraft.
(j) The bulkhead interface design could be either jam-nut or flange
in consultation. If flange
design connector is used, it must be installed such that the flange is located on the
pressurized area of the aircraft. If jam nut connector is used, jam-nut connector should
utilize a lock wire.
(k) Bulkhead interface must be installed such that receptacle pins ar
e on the pressurized
area and receptacle sockets are on unpressurized side of the aircraft.
(l) The bulkhead interface connectors should be electrically bonded to the aircraft.
(3) The KANDU must be electrically bonded to the airframe throug
h contact with the base of the
unit as follows:
• At least one of the four mechanical attachment points must
be used for electrical
bonding. Make sure that the mating surfaces are free from contaminants such as
paints or other non-conductive elements.
• A circular or elongated conductive area must be pro
vided around the mounting hole
of the equipment base plate. A diameter of the conductive area must be 0.12 inch (3
mm) larger than the diameter of the washer.
• The KANDU must include a 0.59 inch (15 mm) diameter bonding measuring point
on one of th
e attachment tabs, as near as possible to the bonding element, but not
on the bonding element.
