3.
Carefully align the flat surface on the feedback or power/brake cable plug
with the flat surface on the motor connector.
4.
Hand-tighten the collar on the plug to fully seat it on the connector.
• The threaded plug requires five to six revolutions.
• The SpeedTec plug requires approximately one-quarter of a revolution.
Do not apply excessive force when mating the cable plug with the motor
connector. If the plug and connector do not go together with light hand
force, realign the flat surfaces and try again.
IMPORTANT
The connector orientation shown is used to clearly show the alignment marker
on each cable socket.
The recommended orientation when installed positions the connectors at the
bottom of the motor.
TIP
A fully-seated threaded plug leaves a small opening, approximately
1…4 mm (0.04…0.16 in.), between the connector and the plug.
ATTENTION
Keyed connectors and cable plugs must properly align and be hand-tightened the
recommended number of turns.
Improper alignment is indicated by the need for excessive force, such as the use of tools,
to fully seat a plug.
Failure to observe safety precautions could result in damage to the motor and cable, and
their components.
