VersaRupter MV Indoor Switch | Installation and Operation Manual 21
Mounting the NM Motor Operator on K-Mechanism
The NM motor operator can be installed on either the oper-
ating mechanism or a left hand shaft extension. The in-
stallation instructions are similar for either application but
instructions can be found for installation on the left side of
the VersaRupter. Further instructions can be found in the
manual for the NM motor operator supplied with the motor
concerning wiring and other data. Use M8 or 5/16ā bolts
and hardware to secure mounting bracket and motor.
1. Ensure that the VersaRupter is in the open position.
Locate the mounting holes for the motor bracket on
the K-mechanism. The bolt in the lower right corner
of the K-mechanism will have to be removed and rein-
stalled to secure the motor mounting bracket. See
figure 37.
2. Rotate the spline on the NM motor till the spacing is
within 4-8 mm as shown in figure 38.
3. Rotate the splined shaft on the K-mechanism till the
spacing is within 3-5 mm as shown in figure 39. This
can be done by hand and does not require an operat-
ing handle.
