SYSTEM DESCRIPTION AND INSTALLATION MANUAL
JetWave™ System

The APM must be electrically bonded to the airframe through contact with the base of the unit or
through a bonding cable attached to M3 earth stud. The APM bonding resistance must be less than
or equal to 2.5 mΩ.
D. KANDU
Refer to Figure 2-26 for outline and installation information. Refer to Figure 2-33 thru Figure 2-36
for
the applicable interconnect diagram.
There are no special tools, fixtures, and equipment required for the installation of the KANDU.
The customer is responsible for the bulkhead connectors.
(1) KANDU to FMA bulkhead interconnect specification is as follows:
(a)
Power and control signals required for the JetWave™ system LRUs installed
outside the
aircraft will be routed through the power and control bulkhead interface connectors
which will be sealed to maintain cabin pressure (max 14.5 PSI (1,000 hPa)) inside the
cabin.
(b) Maximum round trip wiring interconnection resistance between KANDU A3J2 and
OAE-FMA- A5P1 mu
st not exceed 0.326 ohms (considering the 16 AWG wire cables of
length 32.8 feet (10 m)).
(c) It is recommended to use MIL-DTL-38999 series III, inse
rt 19-35, normal keying with 66
contacts as KANDU bulkhead control connector for KANDU interwiring to the
OAE-FMA. To be labeled as BI-control.
(d) It is recommended to use MIL-DTL-38999 series III, insert 17-8, normal keying with eight
contacts as KANDU bu
lkhead power connector. To be labeled as BI-power.
(e) It is recommended to use TNC/N-Type hermetically sealed bulkhead interface in
accordance with MIL-C-87104/2 for
the routing of the TX-IF signals between the
Modman and KRFU. The TX-IF interface to be labeled blue.
(f) It is recommended to use TNC hermetically sealed bulkhead interface in accordance
with MIL-C-87104
/2 for the routing of the RX-IF signals between the Modman and
KRFU. The RX-IF interface to be labeled green.
(g) The bulkhead interface design must be 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.
(h) Bulkhead interface should be installed such th
at recept
acle pins are on the pressurized
area and receptacle sockets are on unpressurized side of the aircraft.
(i) The bulkhead interface connectors must be electrically bonde
d to the aircraft.
(2) KANDU to TMA interconnect specification is as follows
:
(a) KANDU receptacle A3J1 is MIL-DTL-38999/20FD19PN,
series Ill, flange mount
receptacle, insert 15-19, normal keying, with 19 pin-type contacts of size 20 AWG.
Mates with D38999/26FD19SN for aircraft interface.
