Installation and Maintenance Guidelines
This section advises you on how to install your product so it provides safe and reliable service.
To Prolong Motor Life
Thoughtful desi gn and proper maintenance can increase the life of a servo motor.
• Always install the motor with the cable entry point(s) positioned underneath the motor
housing, and provide a drip loop in each cable. A drip loop is a downward bend in the cable
that lets water gather and drip off the cable rather than continue to flow along the cable.
These two installation practices grea tly reduce the potential for moisture related problems.
Recommended Connector Orientat ion with Dri p Loop
• Avoid installing the mo tor with the shaft pointing upward. This orientat ion increases the risk
of contaminant ingress.
• Avoid spraying liquids under pressure directly on the junction of the motor sha ft, housing,
and connect ors, as well as the enclos ure joints. Fluids under pressure can be forced around
worn seals, and contaminate the motor bearings. Bearing contamination will significantly
shorten the life of a servo motor.
ATTENTION
Do not attempt to open and modify the motor. Modifications that can be performed in
the field are described in this manual, other changes should not be at t empt ed.
Only a qualif ied Allen- Bradley employee can service t his type of motor.
