Attach Motor Cables
Follow these steps to attach the feedback and power/brake cables after the motor is
mounted.
1.
Form a drip loop in the cable before attaching it.
A drip loop creates a low spot in the cable. Gravity causes any liquid to flow
to the low spot and away from the connectors, thereby reducing the
potential for any liquid to enter the connector.
2.
If you use a cable with a quick-lock plug, remove the O-ring on the
feedback connector.
The O-ring on the connector dampens the effects of vibration at the
cable-to-motor connection and creates a more secure connection for a cable
with a threaded plug. O-rings interior to the cable plug provide complete
environmental sealing for a cable with a quick-lock plug or a cable with a
threaded plug.
ATTENTION
Make sure that cables are installed and restrained to prevent uneven tension or flexing at
the motor-to-cable connections.
Excessive and uneven lateral force at the motor connectors can result in the connector’s
environmental seal opening and closing as the cable flexes.
Failure to observe safety precautions could result in damage to the motor and its
components.
