HE7200A-BB2327 Install Guide
P/N: 200804
Installation & Wiring
General Information
Generally, modification of the aircraft consists of installing a dedicated single-channel or dual-channel
Iridium antenna with connections for the HE7200A-BB2327.
NOTE: ALL AIRCRAFT ANTENNAS REQUIRE PROFESSIONAL INSTALLATION.
License Requirements
The HE7200A-BB2327 has no licensing requirements.
Cooling Air Requirements
The HE7200A-BB2327 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 HE7200A-BB2327 operates independent of aircraft navigation systems. Therefore, no aircraft
interface is required other than the 10
– 32 VDC Power Input, Power Return and Chassis Ground.
Power Input
The only component of the HE7200A-BB2327 requiring aircraft power is the modem unit. The HE7200A-
BB2327 power interface supports wide voltage input in the range of 10V to 32V DC. The following input
connections are the most commonly used:
•
28 VDC nominal, typically less than 0.5A
•
12 VDC nominal, typically less than 1A
A single 3-amp circuit breaker is recommended to protect the aircraft power distribution system.
Equipment Required But Not Supplied
1. Circuit Breaker: Pull Type Required for HE7200A-BB2327 Modem Unit
Wire Harness Fabrication & Installation Considera tions
Referring to the appropriate section of this manual, assemble a wiring harness as required for the
installation. All wires must be MIL-SPEC in accordance with current regulations. Two-conductor shielded
wire must be used where indicated and be MILSPOEC- 27500 or equivalent specification. Shields should
only be grounded at the Modem Unit end of the interconnect cable. Other ends remain floating. It is
imperative that the correct wiring be used and that proper stripping, shielding, grounding, crimping and
soldering techniques be used at all times. Failure to correct techniques may result in poor performance,
electrical noise or unit failure.
