Remote EMO Connector Wiring
Construct the EMO Remote cable connection following these steps.
•
Select a cable that meets the 16AWG size requirements for pins 3 and 4.
•
Strip the cable conductors as required for the male crimp terminals.
•
Crimp a male terminal onto each conductor in accordance with best practices.
•
Place the connector back shell onto the cable.
•
Insert the conductor male terminals into the wire side of the connector. See
.
•
Thread the connector back shell onto the connector body and tighten firmly.

Cable Connector
4-pin Cable Connector (male pins) (Amp CPC-11 - 206429-1)
Cable Terminal Pins
(4) crimp-tail style male pins for 16 to 18AWG wire size.
Cable Size
16AWG wire required for pins 3 and 4
16 to 18AWG for pins 1 and 2
Cable must be less than 15M (50 feet).
EMO Status Connection
(Output)
