•
Do not install the motor with the shaft pointing upward, as this increases the risk of
contaminant ingress.
•
If design requirements permit, provide shields or junction boxes that protect the motor
housing, shaft seals, connector, and their junctions from product contamination, caustic
agents, and high pressure fluids.
•
Shaft seals are subject to wear and require periodic inspection and replacement.
Replacement is recommended every 3 months, not to exceed 12 months, depending on
use. Refer to
Slinger and Shaft Seal Removal and Installation on page 14
information on shaft seals.
•
If desired, seal the motor front flange to the driven equipment with a bead of food-grade
room temperature vulcanizing (RTV) silicone around the periphery of the motor to
equipment joint. Use of a gasket, or non food-grade RTV silicone, on the mating surfaces
can cause misalignment of the shaft and result in damage to the motor and driven
equipment.
•
Always provide a drip loop in the single motor cable to carry liquids away from the
connection to the motor.
Create a Drip Loop
ATTENTION: Do not spray liquids under high pressure directly on the connector, the motor, or the
enclosure joints.
Fluids under high pressure can be forced into the connector, resulting in an electrical short circuit.
Fluids also can be forced around worn seals, and contaminate the motor bearings. Bearing
contamination significantly shortens the life of a servo motor.
The motor connector is not designed to withstand high-pressure washdown, or washdown with
aggressive cleaning compounds. Position the connector away from direct exposure to cleaning
processes, for example, within washdown-rated conduit or junction boxes.
Failure to observe these safety procedures could result in personal injury or damage to equipment.
Position the motor so that the cable enters from beneath
the motor, and forms a drip loop, as shown here.
The cable lacks a drip loop.
