MAN – FD800JBOX VER RJ45
Installation Instructions
All cabin equipment, such as the FD800JBOX VER RJ45,
should be installed on a non-essential bus and have a
dedicated circuit breaker.
There are (8) #10 mounting locations on the unit: (4) on
the side fl ange and (4) on the bottom fl ange. Flight Display
Systems recommends using at least (4) #10 screws on
the bottom fl ange or the side fl ange. Mounting the unit
with (2) #10 screws on each side is also an acceptable
method of mounting the unit.
The FD800JBOX VER RJ45 requires adequate airfl ow
to prevent overheating. The top and the side ventilation
holes must be unobstructed to allow the forced air
cooling of the system to operate. Flight Display Systems
recommends one inch of clearance to allow adequate
intake and exhaust of air.
Power
This is a 28VDC CPU that requires 1.5 Amps of maximum
continuous steady-state power to operate. The unit turns
on automatically upon power application.
There is a combination power indication light and power
switch on the front of the unit that can be used to turn off
or reset the system if required.
Wiring Suggestions
For balanced signals on twisted pair cable, all shields
should be grounded to the connector at the source, and
fl oating at the display.
Avoid routing video wiring parallel to:
u
AC wiring
u
Strobe wiring
u
DC motor supply cables
u
Inverter cabling
u
Or any other potential noise source.
Power and Ground Wiring
20 AWG wire is recommended for Power and Ground
applications.
This is a 28V DC computer that requires 1.5 amps of
power to operate. To operate properly this product
requires an input voltage of 24-29VDC.
The rated current of the equipment and associated
voltage drop should be taken into consideration when
selecting wire gauge. The following example is based
on an install with a 28VDC power system and a total of
50 feet of wire between the circuit breaker, monitor and
ground.
Example: 22awg wire has 16.2 Ohms per 1000 feet, this
equates to. 81 Ohms for 50 feet. 3 Amps of current
on.81 Ohms will drop 2.43 Volts.

Also, use short heavy gauge wire and a clean tight
connection for ground.
It is the installer’s responsibility to understand the
product’s requirements to install the product in
compliance with industry standards and safety.
