INSTALLATION
Mounting Max-FlexTM Handle Operator
to Enclosure Frame Assembly
A. Drill the mounting holes in the enclosure flange and file all
burrs (Figures 1 and 2). Note the maximum and minimum
drill hole distances in Figure 2.
B. Push the rubber gasket (1) down in the groove of the
handle assembly (2) (Figure 3).
C. The handle and the interlock mechanism are supplied
preassembled from the factory. NOTE: For ease of
assembly, move the operating handle to the ON position.
(up toward the top of the enclosure). Mount the frame (4)
and handle assembly (2) to the enclosure flange (5) with
two #1/4-20 x 3/4 in. socket head cap screws and
lockwashers. Tighten cap screws from within the enclo-
sure (Figure 3).

INSTALLATION DIAGRAMS
Secure E-Ring Connection
A. Rotate the bellcrank (6) clockwise to engage the return
spring (7). Hold the bellcrank in position and place the
plastic washer (8) and connecting link (9) onto the bellcrank
pin (10). Using pliers, secure the connection with an E-
ring (11) (Figure 3).
B. Mount the interlock lever extension (12) to the interlock
lever (3) using #8-32 x 3/8 in. machine screw and
lockwasher. Screw mounts through the threaded lever
extension into the lever (Figure 3).
Operating Note: With the enclosure door open/ the operat-
ing handle cannot be moved from the OFF to ON position
without deliberately defeating the interlock mechanism. In the
OFF position, the interlock can be defeated by pushing the
interlock lever extension (12) downward while moving the
handle to the ON position (Figure 2). With the enclosure door
closed and the handle in the ON position, the interlock can be
defeated by turning the defeater screw (13) on the operating
handle counter-clockwise on left-hand side and clockwise on
right-hand side. When the enclosure door is closed, the door
latch mechanism now automatically defeats the interlock.
C. Weld the door catch bracket (14) to the enclosure door.
(Figures 2 and 4).
NOTE: Holes may be drilled in the door catch bracket using
the projections as centers. User must provide the mount-
ing hardware.
D. Fasten the door catch (15) to the door catch bracket with
two #8-32 x 5/16 in. pan head screws and external tooth
lockwashers (Figure 2).
