2.7 INSTALLING DC NOISE FILTER KIT
The DC Noise Filter Kit is available as a field or
factory installed option as described in Section 1.5.
This kit contains filter choke, Part No. 542-5010-005,
which is installed in the main 13.8-volt line on the PA
board. To install this choke, proceed as follows:
a. Remove both the red and blue power cable leads
from the PC board as shown in Figure 2-5. This pro-
vides the needed access to the front of the choke.
b. Prepare the leads of the choke so that they are
approximately 1/8” below the lowest part of the
choke.
c. Install the choke in the PC board holes provided and
solder the leads using a soldering iron with a long,
narrow tip. Removal of the PA board should not be
required.
d. Install the blue and red power cable leads in the
holes shown in Figure 2-5. Make sure that these
wires or the choke leads do not extend too far into
the board because a direct short to the chassis could
result.
