P810 is assembled as shown in Figure 2-7. While constructing the cable, be sure to pass wires
through the hood before inserting pins into the connector.
FIGURE 2-7. P810 ASSEMBLY
Connector Assembly Procedure (Solder)
Note: Crimping tools are available from ITT Cannon, if desired.
1. Strip wire as shown in Figure 2-7. Maximum wire size is No. 20AWG.
2. Tin exposed lead. Be sure no individual wire strands are free to cause shorts when connector
is assembled.
3. Insert lead in connector pin until lead is visible at inspection port.
4. Heat pin and apply solder as shown until solder wicks into pin cavity and becomes visible
through inspection port. Be careful not to overheat pin or melt insulation on wire.
5. Pass pin through hood and insert pin in connector until a “click” is heard or felt; exert a slight
pull on the wire to assure pin seating.
6. During final assembly:
a. Inspect all wires for individual strands of wire shorting to adjacent terminals.
b. Ease hood into place, do not force.
Connector P810 incorporates a “slide lock” mechanism. Before installing the connector, move the slide to
position the slide’s longer tab away from the connector, mate J810 and P810, then push slide to lock
connector to NAV Unit. To remove P810 from the NAV Receiver, by feel, determine which end of the
slide extends beyond the connector body, press this end toward the connector until it is flush, then remove
the connector.
