1. Refer to the illustration. Unfold Torch Leads individual wires as
needed for access to sockets in the ATC male connector. The
Remote Pendant Adapter wire harness includes three wires ter-
minated with pins. Insert the pins in sockets in the ATC male
connector as follows:
• White wire in socket 3.

• Green wire in socket 8.
There should be an audible click when a pin seats fully in its
socket. Installation may require a tool for access to the sockets.
2. Press the Adapter wire harness into the knockout in the shell half.
The wire tie on the harness must be positioned inside the shell
half.
3. Slide the locking ring into position on the male connector.
4. Position the wire bend relief on the Torch Lead.
5. Fit the shell halves against the male connector and wire bend relief. Align keys in grooves in the shell halves
with notches in the male connector ring. Press the shell halves tightly together by hand. Ensure that the
center assembly cannot rotate within the shell halves.
6. Fasten the shell halves together with the screws removed previously. Tighten the screws securely.

at one end. Install the socket in position 8 on the female receptacle.
4. Pass the grounding wire through the knockout in the shell half.
5. Position the wire bend relief on the Torch Lead or Adapter Lead.
6. Fit the shell halves against the male connector and wire bend relief.
Align pins in grooves in the shell halves with notches in the male
connector ring. Press the shell halves tightly together by hand.
