6.5 Cooling Requirements
The echoUAT is designed to meet all applicable requirements without
forced-air cooling. Attention should be given to the location of the
installation in order to avoid the transfer of heat into the unit from other
electronic devices to avoid damage to the echoUAT device and voiding the
warranty.
7. Wiring Considerations
7.1 Power Wiring
There are technical benefits for using twisted, shielded wiring for the
echoUAT installation including improved electromagnetic emissions and
susceptibility. Aviation grade wire is recommended to interface the
echoUAT to the aircraft systems. A 3A circuit breaker may be used when
echoUAT and SkyFYX power inputs are combined on the same circuit.
The maximum distance between the echoUAT and the DC power source is
determined by the wire resistance; IE the voltage drop across the power
source to the EchoUAT unit. The echoUAT requires a resistance of less
than 0.5 ohms in the power line for satisfactory operation. The following
table provides guidance for a typical aircraft wiring.
