Operation - Honeywell KHF 1050 System Installation Manual

Preliminary - Subject to Change Without Notice
When the cables are installed in the aircraft, they must
be supported firmly enough to prevent movement and should
be carefully protected against chafing. Additional
protection should also be provided in all locations where
the cables may be subject to abuse.
In wire bundles, the cabling should not be tied tightly
together as this tends to increase the possibility of
noise pickup and similar interference.
cables through the airframe, the cables should cross
high-level lines at a right angle.
Wiring harness and antenna cable should be routed in such
a manner that they do not adversely affect the operation
of the shock mounts.
The installer must be knowledgeable of any system
variation peculiar to the installation such as strapping
requirements described in section 5.D. Furthermore, the
installer should use ARINC Characteristic 735 as a guide
and reference throughout the fabrication and installation
of the cabling in the aircraft.
5.C.(2) Interface Capability and Requirements
All RF coaxes must be double shielded.
In systems that employ speech processing, special care
should be taken in the routing of the microphone input
line.
be routed in the same harness containing high current
lines.
5.C.(3) Primary Power and Circuit Breaker Requirements
All units in the KHF 1050 system should be protected by
circuit breakers in the positive primary power lines. The
KPA 1052 should use an individually dedicated 30 amp
slow-acting circuit breaker. The KAC 1052 and KRX 1053 can
share a common 5 amp circuit breaker, or be individually
protected by 5 amp circuit breakers for each. If a PS440
controller is used in the system, it can share a circuit
breaker with the KRX 1053. An MCDU or an RM-855 must not
share a circuit breaker with any HF system component.
