Soep 3 (NF frame Nnly): If this is a fixed circuit breaker, skip this step
and proceed directly to Step 4. If this is a drawout circuit breaker,
unscrew the three captive screws holding the secondary mounting
bracket in place. This will permit the secondary mounting bracket to
be moved down, providing access to the key interlock assembly's
threaded mounting holes. No wires or connectors need to be removed
or unplugged.

Soep 4: Refer to Figure 1 for orientation purposes. Remove the key
(B) from the cylinder (C), then remove the two mounting screws (G)
from the back of the cylinder. Attach the metal mounting bracket (D)
to the back of the cylinder using the mounting screws just removed.
Note that the embossed letter or symbol on the cylinder should be in
vertical orientation and point toward the two bracket mounting screws.
Soep 5: The lever assembly (J) can now be attached to the square
shaped shaft on the back of the cylinder (C). It is secured to the square
shaped shaft by a mounting screw (I) and mounting nut (H). Usually
the lever assembly comes with the mounting screw and nut already
installed. If this is not the case, install the screw through one side and
the nut on the opposite side in a recessed hole made to accommodate
the nut. Push the lever assembly onto the shaft until it touches the
mounting bracket tab. Make sure the lever assembly is straight when
being installed onto the shaft. Once installed, firmly tighten the
mounting screw (I) into the nut (H).
Soep 6: Install the button support (K) by sliding it over the mounting
plate (D). Ensure the grooves are seated against the mounting plate on
top and bottom.
