Select a Location
Select a location for the BCU that is in a corrosion-free, clean, indoor
environment. Consider both security and control wire lengths when mak-
ing the selection. The location should limit access to the BCU to operating
and service personnel.
To extend the life of the BCU electronic components, ensure that the
selected location avoids extreme operating conditions (including excessive
vibration) whenever possible.
CAUTION
Avoid Equipment Damage!
Install the BCU in a location that is out of direct sunlight. Failure to do
so may cause the BCU to overheat.
To avoid malfunctions caused by electrical interference, do not install the
BCU near high-power radio signals, electrical switching gear, power
buses, large motors, or other sources of electrical noise.
Verify Conformance to BCU Specifications
Ensure that the location conforms to BCU specifications. BCU specifica-
tions are shown in Table 2. A dimensional drawing of a BCU is shown in
Figure 4 on page 17.
