2.6 Aircraft Wiring
The installation of the device(s) depends on the type of aircraft and its equipment
and therefore only general information can be given in this section.
•
Use only cables which are qualified for aircraft use (self-extinguishing).
•
Use AWG 20 for power supply and AWG 24 for other cables.
•
Interface lines TX-A/TX-B and RX-A/RX-B are each to be laid as
2-core twisted and shielded cables.
•
Attach sleeves over the solder joints on the equipment connector.
•
HF cable should not be included in the cable harnesses.
•
Use the recommended fuses in the power supply line for the protection of
the application, see "Technical Data", page 19.
•
Examine the wiring carefully before power up the device(s) and examine
particularly correct connection of the power supply lines.
Electrical Bonding and Grounding
The ACU6100 has a threaded grounding bolt at the housing. Use this point as grounding contact.
•
Make sure that the device is correctly connected to aircraft ground
(structure).
•
Make sure that the electrical bonding area is protected in order to
prevent corrosion.
•
Make sure that the resistance between the bonding component and any
point of this item of equipment do not exceed 2.5
mΩ.
