Notes:
A) Enclosures with a Flange Thickness less than 3/16" use dimensions above.
B) Enclosures with a Flange Thickness 3/16" and greater use dimensions in Mounting Kit 1494V-H3.
C) Multi-Door Enclosures use dimensions in Channel Support Kit 1494V-H4, if handle is mounted atop channel.
D) The door catch mounting bracket is provided with projections for welding; however, holes can be drilled in the bracket using the
projections for locating hole centers. After proper location, use the bracket as a template and drill corresponding holes in the
enclosure door. Fasten the bracket with hardware supplied by user. If properly assembled, the hardware should not be accessible for
tampering with by unauthorized personnel.

Testing of Circuit Breaker
1. Verify that the circuit breaker can be turned on by moving the defeater lever downward and moving the disconnect
handle to the ON position.
2. If the circuit breaker does not turn on, loosen the (2) screws and adjust the toggle adjustment plates toward the line
terminals until the circuit breaker turns on when the disconnect handle is in the ON position. Tighten the (2) toggle
adjustment plate screws to 25 - 30 lb-in.
3. If the circuit breaker still can not be turned on unhook the spring, remove hitch pin and separate threaded rod and
handle link. Turn threaded rod one full turn counterclockwise. Reattach threaded rod and handle link, hitch pin and
spring. Repeat Step 1 and if necessary Step 2.
4. Verify that the circuit breaker can be turned off by moving the disconnect handle to the OFF position.
5. If the circuit breaker can not be turned off, loosen the (2) screws and adjust the toggle adjustment plates toward the
load terminals until the circuit breaker turns off when the disconnect handle is in the OFF position. Tighten the (2)
toggle adjustment plate screws to 25 - 30 lb-in.
6. If the circuit breaker still can not be turned off and if no adjustment of the threaded rod was made in Step 3 then
unhook the spring, separate threaded rod and handle link and remove hitch pin. Turn threaded rod one full turn
clockwise. Reattach threaded rod and handle link, hitch pin and spring. Repeat Step 4 and if necessary Step 5.
7. Verify that the circuit breaker can be reset after manually tripping when circuit breaker is in the ON position.
8. Manually trip the circuit breaker while in the ON position, then move the disconnect handle to the Off-Reset
position.
9. If the circuit breaker does not reset, loosen the (2) screws and adjust the toggle adjustment plates in small
increments toward the load terminals.
Note: Repeat this procedure until the circuit breaker can be reset.
Note: Do not adjust the toggle adjustment plate too far: this will prevent the disconnect handle from moving to the full OFFReset position.
10.Tighten the (2) adjustment plate screws to 25 - 30 lb-in.
11.Verify that the circuit breaker can still be turned on following the above steps.
Note: Twisting of the bail mechanism is acceptable when the handle is in the full ON or full OFF position.

3. Fasten the base assembly to the support bracket with (2) screws. Tighten to 7 - 10 lb-in.
4. Attach the assembly from Step 3 to the ear on the support plate with (2) screws. Tighten to 7 - 10 lb-in.
5. Attach the auxiliary contact with the safety guard to the base assembly.
Note: If a single auxiliary contact is used, it must be positioned nearest the cam, in slot A shown above. A second auxiliary contact
would be positioned in slot B.
D
Testing of Auxiliary Contacts
1. Make sure the auxiliary contact and adapter kit (circuit breaker) have been installed in the proper position.
2. If the auxiliary contact (circuit breaker) is N.O., place the probes of the continuity tester across both terminals with the
disconnect handle in the OFF position; there should be no continuity.
3. Move the disconnect handle to the ON position and place the probes of the continuity tester across both terminals; there
should be continuity.
4. If the auxiliary contact (circuit breaker) is N.C., place the probes of the continuity tester across both terminals with the
disconnect handle in the OFF position; there should be continuity.
5. Move the disconnect handle to the ON position and place the probes of the continuity tester across both terminals; there
should be no continuity.
