Motor Lead Termination
Motor leads are normally terminated using a Connector or Terminal Box (see Figure
2-8) or Flying Leads. When no termination is provided and the motor leads just exit
the motor housing, this is called “Flying Leads”. For ying leads, refer to the motor
packing list to determine the lead conguration.

Connector Termination Terminal Box Termination
Strain Relief (Mounted at Terminal Box)
The motor cable is terminated at the Terminal Box using a Shielded Strain Relief Connector.
Figure 2-9 shows the components.
1. Strip the outer shield from the cable to expose the conductors and shield.
2. Slip the Strain Relief components onto the cable in the order shown.
3. Fold the Shield wires over the end of the Contact Carrier.
4. Slide the Threaded Adapter onto the Contact Carrier until the Carrier is
completely inserted into the Adapter.
5. Slide the Gasket into the Contact Carrier.
6. Slide the Adapter Cover onto the Threaded Adapter and Tighten. As it is
tightened, it compresses the Gasket against the Cable to form the strain
relief and securely hold the cable.
7. The assembly can be inserted into the Terminal Box and secured.

Feedback Termination
Connections for Feedback cables are different for each type of feedback device.
Standard devices are: Resolver, Halls (Hall Effect), Incremental Encoder with Halls,
and Absolute Encoders including SSI, EnDat, BiSS, and Hiperface.
Custom feedback devices are also available. Request a drawing of your feedback
device to determine the pin−out and/or wire color codes.
