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).

Drawing 10-2)

Basic Requirements  

 

The following basic requirements have to be insured while installing FMS65X and 85X 

 

 

Choose a location on the instrument panel that can be accessed by both pilot and 

co-pilot 

 

Ensure that the airflow to the unit is not restricted 

 

Ensure that the location selected for installation is not subjected to dust or dirt 

 

Ensure that the air intake on the front of the unit is not obstructed or blocked in 

any manner
