Prepare all of the shielded cables as shown in Figure 3-3. Refer to Figure 3-5 for details of the shield
termination to the connector backshell. Skip to step 5 below for wires with no shielding.
1. At the end of the shielded cable (11), strip back a 2.5” maximum length of the jacket to expose
the braid. Remove this exposed braid. Carefully score the jacket 1/4” to 5/16” from the end and
remove the jacket to leave the braid exposed.
NOTE
Solder sleeves with pre-installed shield drains should be used instead of separate shield
terminators and individual wires, although separate shield terminators and individual
wires can be used.
2. Connect a 20 or 22 AWG wire (13) to the exposed shield of the prepared cable assembly. (See
Figure 3-2). AC 43.13-1B Chapter 11 may be a helpful reference for termination techniques. Note
that 3 methods are shown in Figure 3-2. The Daisy-Chain method should only be used on P1001
if there are insufficient holes in the shield block to accommodate the shields. Limit the combined
length of the daisy chained shields to 3” maximum.
NOTE
A preferred solder sleeve is the Raychem S03 Series with the thermochromic
temperature indicator. These solder sleeves come with a pre-installed lead and
effectively take the place of items 12 and 13. For detailed instructions on product use,
refer to Raychem installation procedure.
3. Slide a shield terminator (12) onto the prepared cable assembly (11) and connect the wire (13) to
the shield using a heat gun approved for use with solder sleeves. The chosen size of solder sleeve
must accommodate both the number of conductors present in the cable and the wire (13) to be
attached.
4. Repeat steps 1 through 3 as needed for the remaining shielded cables. Note that a maximum of 2
shields can be daisy-chained together.
5. Crimp pins/sockets (14) onto the wires and terminate in the connector (10) in accordance with the
aircraft wiring drawings.
6. For P1001, install the configuration module wires into the connector. Refer to Section 3.6.3.2 for
instructions on installing the configuration module.
