3.4 Wiring harness

Terminals

3.5 Power supply

The factory produced wiring harness provides a simple and safe
installation of Altair. In addition, even though the following in-
stallation examples all use the factory wiring harness, these instal-
lations are possible without the factory wiring harness.
The wiring harness provides the following connectors and termi-
nals:
Power supply to Altair
Power supply from Altair to peripheral devices
Audio outputs to amplifier or Vega
2xRJ45 IGC connectors, for communication with peripheral
devices
1-Wire bus terminals
The wiring diagram of the factory harness is documented in Ap-
pendix D. When custom harnesses are needed, it is recommended
to adapt the factory harness design.
The connectors X2 and X3 are special terminals of Wago Cage
Clamp type that can accept bare wires up to a cross sectional area
2
of 0.75 mm (AWG20). To connect a wire to these terminals, first
strip 4-5 mm of the insulation. Then insert the supplied WAGO
tool in the square hole next to the desired slot to open the terminal.
Insert the wire, then remove the WAGO tool. Check that no bare
wires are exposed after completion, and gently tug on the wire to
ensure the clamp is secure.
A voltage supply with a current limiting safety device must be se-
cured, to cut the power in the event of an overload in the voltage
supply. The safety device must be marked clearly, e.g.
. The best option is to use a resettable device such as a
ga/Altair
circuit breaker, however a slow-blow fuse is acceptable. The fuse
or circuit breaker should be rated for 2.5 Ampere.
Ensure the power wires and circuit breakers have low resistance
otherwise the higher current drains of Altair will result in wasted
battery power.
Use twin core power cable where possible to prevent magnetic
interference with the aircraft compass.
