INSTALLATION & WIRING
LICENSE REQUIREMENTS
The ACH1000 Control Head has no licensing requirements.
COOLING AIR REQUIREMENTS
The ACH1000 has very low power usage so forced air cooling is not required for any of the components.
However, units should be kept away from heat sources.
AIRCRAFT INTERFACES
The ACH1000 operates independent of aircraft navigation systems. Therefore, no aircraft interface is
required other than optional interface to the audio controller and the 18-33Vdc Power Input, Power
Return and Chassis Ground.
POWER INPUT
The ACH1000C requires aircraft power.
The ACH1000 power interface supports wide voltage input in the range of 18V to 33V DC. The following
input connection is the most commonly used:
28 VDC nominal, typically less than 0.5A (up to 1A max)
A circuit breaker is recommended to protect the aircraft power distribution system.
EQUIPMENT REQUIRED BUT NOT SUPPLIED
1. Circuit Breaker
2. Interconnect Wiring for power
3. Interconnect Wiring for data and audio
4. Mounting Hardware
