SECTION 2
PRE-INSTALLATION CONSIDERATIONS
2.1
COOLING
No direct cooling is required. As with any electronic equipment, overall reliability may be increased if the
unit is not located near a high heat source or crowded next to other equipment. Means of providing some
airflow is considered beneficial.
2.2
EQUIPMENT LOCATION
The MD41-1817 ACU must be mounted as close to the pilot’s field of view as possible. The unit depth,
with connector attached, must also be taken into consideration when selecting an appropriate location.
Allow at least 3 inches of space behind the unit for connector attachment and removal.
2.3
ROUTING OF CABLES
Care must be taken not to bundle the MD41 series ACU logic and low level signal lines with any high
energy sources. Examples of these sources include 400 Hz AC, Comm, DME, HF and transponder
transmitter coaxial cables. Always use shielded wire when shown on the installation print.
Avoid sharp bends in cabling and routing near aircraft control cables. Also avoid proximity and contact
with aircraft structures, avionics equipment, or other obstructions that could chafe wires during flight and
cause undesirable effects.
2.4
LIMITATIONS
Note that this product is part of an incomplete system. It is designed to be installed with other applicable
equipment to provide functionality for main battery systems.
