3:2 MAIN SWITCH REMOVAL AND REPLACEMENT

To remove the main normal or emergency switches, first electrically isolate the

transfer switch from all power sources.

a) Disconnect all cables and wiring from the switch terminals.

b) Open the cover on the operating arm, remove the pin slider and close the

cover.

c) Remove the switch operating arm assembly by removing the four screws

securing the pivot bracket to the back panel and lift the arm assembly

complete with bracket from the back panel.

d) The individual switches can now be readily unfastened and removed from

the back panel.

Replacement is the reverse of the above procedure. Note when replacing

the arm assembly, ensure that the switches are set one "off" and one "on"

and that the rollers on the arm springs equally straddle the switch operating

levers. Tighten the pivot bracket screws equally to ensure controlled

deflections of the arm springs.

3:3 MOTOR REMOVAL AND REPLACEMENT

– Electrically isolate the transfer switch from all power sources.

– Note the wire connections to the 12 position terminal connector.

– Cut the motor connection wires (white and black) approximately 3 inches

from the terminal block. Strip each wire ¾ of an inch, and attach the

corresponding leads from the new motor with wire connectors approved

for 18 gauge wire. Remove the arm assembly as previously described.

– Remove four screws securing the motor bracket to the back panel.

– Lift the assembly out of the transfer switch.

– Remove the crank and cam assembly by loosening the set screw in the cam

arm.

– Remove four screws securing the motor to the underside of the motor

bracket. The motor can now be removed.
