WARNING
Risk of Energy Wheel Collapsing!
Failure to follow instructions below could cause the
energy wheel to collapse under the technician’s
weight which could result in severe injury.
Before laying across the energy wheel, add extra
support by placing a rigid board across the span of
the energy wheel cassette.
3. Support segment with one hand while removing 1/4 -
20 flat head retaining screw in the wheel hub with 5/32"
Allen wrench, see Figure 99, p. 150.

4. Carefully slide the segment out from between the hub
plates, and remove from the wheel.
5. Reinsert the 1/4 - 20 screw in the removed segment
nose to avoid loss.
6. Rotate the wheel and continue this procedure to
remove all segments.

WARNING
Hazardous Voltage!
Failure to disconnect power before servicing could
result in death or serious injury.
Disconnect all electric power, including remote
disconnects before servicing. Follow proper lockout/
tagout procedures to ensure the power can not be
inadvertently energized. Verify that no power is
present with a voltmeter.
Inner Segment Replacement
1. Disconnect all electrical power.
2. Secure wheel from rotation.
CAUTION
Sharp Edges!
Failure to follow instructions below could result in
minor to moderate injury.
The service procedure described in this document
involves working around sharp edges. To avoid being
cut, technicians MUST put on all necessary Personal
Protective Equipment (PPE), including gloves and
arm guards.
3. Remove 1/4 - 20 flat head retaining screw from the
inner segment nose with 5/32" Allen wrench.
4. Rest the edge of the segment on the support flange on
one wheel spoke and slide it until the segment nose is
fitted firmly in the wheel hub and the segment screw
hole is aligned with the hub slot.
5. Reinsert 1/4 - 20 screw into the hub / inner segment
and tighten until the screw is firmly seated, see Figure
99, p. 150.

technician which could result in death or serious
injury.
Disconnect all electric power, including remote
disconnects before servicing. Follow proper lockout/
tagout procedures to ensure the power can not be
inadvertently energized.
1. Disconnect all electrical power.
2. Secure wheel from rotation.
3. Rotate out the two segment retainer latches, one for
each side of the selected segment opening, such that
they are 90° from the wheel rim. See Figure 99, p. 150.
4. Set the segment in the gap between the segment
retainer latches, pressing it toward the center of the
wheel and inward against the spoke flanges. See
Figure 102, p. 152. If hand pressure does not fully seat
the segment, insert the flat tip of a screwdriver between
the wheel rim and the outer corners of the segment and
apply gentle force while guiding the segment into place.
Be careful not to bend the wheel frame or the segment
