Installation of 2 Amp CB
A 2 Amp circuit breaker will need to be
installed for the FMS 65X and 85X. A
typical install is shown in the figure.
The CB should ideally be mounted on
the Essential Bus that will not be
automatically isolated in the event of a
generator failure.
The CB must be properly annotated or
labeled as shown in the figure. Ensure
that the power and ground return wires
are twisted together at 6 or more turns
per foot.
Connect Pin 1 of the FMS 65X and 85X unit to +14 V DC or +28 V DC as applicable to the aircraft
and the type of FMS 65X and 85X voltage rating through the 2 Amp CB installed for the unit.
Connect the ground return wire (Pin 5) to a suitable aircraft structure near the CB panel. The CB
will provide power supply to three components – Pin 1 of FMS 65X and 85X, the CO warning
light and the optional cabin altitude warning light. The circuit diagram is shown in detail in
Supplement 2 to this manual (page 27).
