Mounting the HE/HM Operating Handles
The HE and HM operating handles include a bevel gear and
front mount universal joint. The HE handle has an arrestor
ring that must be pulled out as the removable handle is
rotated to open or close the switch. The HM handle must
be used if manual operation is desired with use of the NM
motor operator. The HM handle does not have the arrestor
ring.
Ensure the opening spring is not charged if an A-mechanism
is installed.
1. Install the bevel gear onto the operating shaft of the
mechanism or grounding switch. Easiest if done be-
fore the VersaRupter is installed into an enclosure.
See figure 91 for proper orientation of the bevel gear.
2. Install the front mounted universal joint onto the en-
closure using a 17 mm socket. Fabricate a 3/4” pipe
to connect the bevel gear and front universal joint.
The bolt holes should not exceed 10 mm. Refer to
drawing S-20361 at the end of this document for fabri-
cation instructions.
For HE handles:
3. Remove the Seeger ring, spring and nut. See figure
92.
4. Slide the arrestor ring off of the splined shaft. See
figure 93. The splined shaft should be free to rotate.
5. If paired with an A-mechanism, use the removable
handle to charge the A-mechanism.
6. Test the installation by opening and closing the
switch.
7. Slide the arrestor ring back onto the splined shaft.
8. Slightly pull the arrestor ring out so it clears the lock-
ing tab on the front universal joint.
9. Close the VersaRupter and ensure the front universal
joint indicates the switch is closed as in figure 94.
10. If not, remove the arrestor ring and reinstall it posi-
tioned 2-3 teeth rotated to the right.
11. Once in the correct position, reinstall the spring, nut,
and Seeger ring.
12. Warning! Always apply the information label supplied
with the HE/HM handle during installation. Labels
must be close to the body of the handle for proper
notification during service.
