ATTENTION: To prevent electrical shock, disconnect from power source before installing or servicing. Install in
suitable enclosure. Keep free from contaminants.

Fuse cover must be installed for safe operation.

Check that disconnect switch is in OFF position before assembly.

General Information

The Cable Operated Mechanism provides a means of externally operating the disconnect switch and can be applied
to enclosures of varying heights and depths. The handle can be used with NEMA 1, 3R, 12, 4, 4X enclosure
applications, depending on the accessory components selected. An operating handle, flexible cable, and
mechanism are required for standard application. Different lengths of cables are available for use with the wide
range of depths of various enclosures (3' through 10'). When selecting the length of the Flexible Cable, ensure
Minimum Bending Radius of 6 inches is maintained to operate properly. (See Figure 1-2). The standard method of
shipment includes the mechanism preset at the factory. If minor field adjustments are required see Figure 1-5.

ATTENTION: Before any installation or maintenance is performed, make sure that the disconnect switch is not energized.

Bulletin 194RC Installation

1. Install disconnect switch with four #10-32 screws. (See Figure 1-1).

2. Install handle to enclosure by placing the outer handle mechanism with the attached gasket over the enclosure cutout. Insert

the top mounting screw with lockwasher through the enclosure and thread it into the outer handle mechanism for a few turns but
not all the way. (See Figure 1-2).

3. Slide the toggle mechanism assembly over the top handle mounting screw. Insert the bottom handle mounting screw and
lockwasher through the toggle mechanism assembly, through the enclosure and into the handle. Tighten both mounting screws
to specified torque. (See Figure 1-2).

4. Assemble adapter link to actuator link. Tighten to specified torque. (See Figure 1-3).

5. Align adapter link with the bell crank. Attach bell crank to adapter link with shoulder bolt and nut. Tighten to specified torque.

(See Figure 1-4).

6. Mount door hasp to handle using the two screws provided with the handle. (See Figure 1-2).

7. Operate handle mechanism to ensure functionality. To operate either close door or defeat door interlock.

8. If minor adjustments are necessary, refer to adjustment checklist (Page 3).

9. Install appropriate door hardware (supplied). (See Figure 1-7).
