a. Refer to the circuit breaker table in Electrical
Schematics on page 69.
b. Turn the main power switch (MP) off.
c. Loosen the two screws connecting the wires
and bus bar to the circuit breaker that will be
replaced, then disconnect the wires.
d. Pull the locking tab out 1/4 in. (6 mm) and pull
the circuit breaker away from the din rail. Install
the new circuit breaker. Insert the wires and
tighten down all screws.
