consideration of the location of this module is necessary. Some of
the items to be considered include:
• Space
• Available power supply
• Environmental conditions (temperature, humidity, etc.)
• Length of cable runs

3.3 Cautions and Warnings
3.3.1 It is important to do a pin-to-pin power and ground check on all
connectors. Ensure that power and ground are applied only where
specified. Damage to the unit may result if power or ground is
applied to the wrong points.
3.3.2 DO NOT connect or disconnect the module while power is applied.
3.3.3 DO NOT remove any factory-installed screws. Damage to the units
may result and void any warranties.
3.3.4 NO scheduled maintenance is required to ensure continued
airworthiness.
3.3.5 ESD (Electro Static Discharge) guidelines shall be followed.
3.4 Wiring Requirements
3.4.1 Introduction
The installing agency must supply and fabricate all external cables
and mating connectors. The length and routing of external cables
must be carefully studied and planned before attempting installation
of the equipment. Allow adequate space for installation of cable
and connectors. Avoid sharp bends and placing cables near
aircraft control cables. Maintain a MINIMUM clearance of three (3)
inches from any control cable. If wiring is run parallel to
combustible fluid or oxygen lines, maintain a separation of six (6)
inches between the lines.

ground wires shall be grounded within twelve inches of the unit. All
wires shall be in accordance with the standard military specification
of MIL-W-22759 or equivalent. Twisted, shielded cable shall be in
accordance with the standard military specification of
MIL-DTL-27500 or equivalent. Protect power wires with circuit
breakers or fuses located close to the electrical power source bus.
3.5 Physical Characteristics
3.1.4 Refer to Section 5.0 for unit dimensions.
3.1.5 Refer to Section 6.0 for attachment points.
3.1.6 When mounting the unit, allow sufficient space for mating
connectors.
