AVERTISSEMENT:
Avant d'installer tout accessoire,

ressorts d'armement
Install the Mechanical Counter with the following
procedure.
1.
Turn off the breaker, discharge the springs, and
turn off control power to the accessories and

breaker, rack it out.
2.
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.
4.
On the breaker cover, use a screwdriver to punch
out the knockout above the
CHARGE-DISCHARGE
flag opening.
5.
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
