2.6. Installation and Configuration
Connection to the following equipment is required as minimum for 620X transceivers:
• Power supply
• Antenna
• Microphone (direct or via external audio panel)
• Headphone or speaker (direct or via external audio panel)
• Push-To-Talk (PTT) switch
Use only cables which are qualified for aircraft use (self-extinguishing).
Use AWG 20 for power supply and AWG 22/24 for other cables.
Fit sleeves over the solder joints on the equipment connector. Crimp
connectors are also available from Becker.
Protect the power supply with a 7.5 A fuse.
The VHF transceiver is protected internally by a 5 A fuse.
• Type-specific cable harnesses are also available for the aircraft wiring (contact Becker
Avionics for detailed information).
• No RF antenna cables or HF cables should be included in the cable harnesses of the
system. Avoid routing of the cable loom along with other wiring, which carry audio power
or pulses.
• Check the wiring carefully before powering up the unit and check particularly that power
supply lines are not interchanging.
