4.5 Mounting
In cooperation with a maintenance shop, location and kind of the
installation are specified. The maintenance shop can supply all
cables. Suitable sets of cables are available from f.u.n.k.e.
AVIONICS GmbH.
Select a position away from heat sources. Care for adequate
convection cooling.
Leave sufficient space for the installation of cables and connectors.
Avoid sharp bends and wiring close to control cables.
Leave sufficient lead length for inspection or repair of the wiring of
the connector.
Bend the harness at the rear connectors to inhibit water droplets
(formed due to condensation) from collecting in the connector.
For mounting details/drawing refer to chapter 4.11.2

auto, the dynamic microphone connection has priority over the standard
microphone.

circuit breaker (4 Amp. slow-blow)!
