INSTALLATION
The program mer mounts to the upper left of the breaker
as shown in Fig. 1 00. It mounts to the bracket assem b ly
shown in Fig. 82. Referring to Fig. 82 , the guid e p ins mate
with the hole on either side of the programmer connector.
They provide the n ecessary alignment for the connector
engagement. The locking lever engages with the pin wh ich
is assem b led to the programmer frame and secures the
program mer to the mounting bracket.
I nstallation .is as follows:
a. I nsert the guide pins into the holes and p ush on the
programmer, engaging the connectors.
b. Th e locking lever is released , securing the program­
mer.
c. Verify that the locking lever did engage the program­
mer pin.
To remove the program mer:
a. Pull out locking lever, which will release the program­
mer pin. Remove the programmer.
