Install the Mechanical Counter with the following

Loosen the four
#8-32
screws on the trim-plate
assembly and remove the trim plate.
3.
Loosen the four screws at the corners of the
breaker cover. Remove the cover from the breaker
face.

On the breaker cover, use a screwdriver to punch
out the knockout above the

Hold the ON-OFF flag towards the ON position,
then carefully insert the flag lockout plate to retain
the flag in this position. The flag lockout plate
should be installed close to the side frame on
