INSTALLATION
The programmer mounts to the u pper left of the breaker
as shown in Fig. 1 00. It mounts to the brac ket assem b ly
shown in Fig. 82. Referring to Fig. 82, the guide pins m ate
with the hole on either side of the programmer connector.
They provide the necessary alignment for the connector
engagement. The locking lever engages with the pin which
is assem b led to the program mer frame and secures the
programmer to the mounting bracket.
I nstallation is as follows:
a. I nsert the g u ide p i ns into the holes and push on the
programmer, engag ing the con nectors.
b. The locki ng lever is released , securing the program­
mer.
c. Verify that the locking lever did engage the program­
mer pin.
To remove the programmer:
a. Pull out locking lever, which will release the program­
mer pin. Remove the programmer.

terminals. These phase sensors are used when the hi­
level instantaneous RMS-9 option (' H ' -option) is req uired .
Fig . 1 0 2 shows an ' H ' -option phase sensor. When the
' H ' -option phase sensor is instal led, there are four leads
con nected to it. There is no polarity associated with the
special winding connection. Fig. 1 0 2 shows the connec­
tions for the add itional ' H ' -option windings.
