Installing an HPK Motor
Observe the following when installing an HPK-Series motor.
1. Rotate the wiring junction box and position the motor so the junction box may be
accessed for initial wiring and occasional verification of and maintenance to the wiring
connections.
Refer to Cable Orientation for Drip Loop on page 6 for a visual reference of correct
motor and cable positioning.
2. Properly mount the motor.
Refer to the motor outline drawings for dimensions. If necessary, shim the motor to
achieve proper alignment of the shaft.
3. Align the motor shaft on the index pulse.
The index pulse occurs on a single-turn encoder when the shaft key is aligned with the
top of the motor. Refer to the motor outline drawings for a visual reference of this
alignment.
4. Form a drip loop in the cables directly before each cable enters the motor.
A drip loop lets liquids gather and drip off the cable rather than flow along the cable to
an electrical connection or the motor. Refer to
Cable Orientation for Drip Loop on
page 6 for a visual example.
5. Remove the access cover on the junction box, and rotate the box in 90° increments to
improve cable access.
ATTENTION: Do not strike the shaft, couplings, or pulleys with tools during
installation or removal.
Damage may occur to the motor bearings and the feedback device if sharp
impact to the shaft is applied during installation of couplings and pulleys.
Failure to observe these procedures could result in damage to the motor and its
components.
ATTENTION: Be sure that feedback cable is installed and restrained to
prevent uneven tension or flexing at the cable connector.
Excessive and uneven lateral force at the feedback connector may result in the
connector’s environmental seal opening and closing as the cable flexes.
Failure to observe these safety procedures could result in damage to the motor
and its components.
