Take precautions during a lift to prevent hazardous overload due to deceleration, acceleration, or
shock forces caused by abrupt raising or lowering, or swinging and twisting of a suspended
motor.
Lifting Guidelines
For unusual conditions, such as side-wall and ceiling mounting of horizontal motors and
installation of vertical motors shipped in a horizontal position, special precautions must be
taken. We recommend that an experienced rigger be employed.
To Prolong Motor Life
Thoughtful design and proper maintenance can increase the life of a servo motor. The following
are guidelines to maximize the life of a servo motor.
• Always provide a drip loop in a cable to reduce the potential for moisture related
problems. 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.
• Avoid installing the motor with the shaft pointing upward. This orientation increases
the risk of contaminant ingress.
• Environmentally-sealed connectors and cables are required to achieve an International
Protection (IP) rating of IP54 for the motor.
ATTENTION: Eyebolts may unscrew during lifting. Prior to lifting, check the
eyebolts to verify that they are tight and attach lifting equipment to restrict
turning during the lift. Alternatively, lift the unit on a platform or with a sling.
Failure to observe this precaution could result in bodily injury.
