trip rod to 0.100 inches. Use a 0.100 inch diameter rod as
shown in Fig. 2-6. Set the adjuster end of the trip rod and
lock it in place with the jam nut.
2. As the crossbar travels between the "breaker closed"
and "breaker open" positions, the tang of the actuator
bracket must clear the buffer stud. If insufficient clearance
exists, loosen it's two mounting screws and rotate the
bracket clockwise to take up mounting hole slack. Retighten
screws.
2.5-Programmer Mounting
Installation
The MicroVersaTripTM Programmer mounts to the left side
of the front channel. A mounting bracket is shock mounted
to a plate that is assembled to the front channel as shown in
Fig. 2-7. Use Loctite or an equivalent retaining material on
the mounting screws for the plate assembled to the front
channel.
For breakers equipped with an ECS or SST system, replace
the existing plate and mounting bracket with the new ones
provided. Assemble the mounting bracket to the plate using
the holes closest to the front of the breaker. See Fig. 2-7.
For EC or Power Sensor equipped breakers, the holes for the
new plate may have to be added to the front channel. The drill

pattern for these holes is given in Fig. 2-8. Once the plate is
installed, assemble the mounting bracket to the plate using
the holes closest to the front of the breaker, See Fig. 2-7.
2.6-Programtner Harness
Installation
The programmer harness consists of the mating 36 pin pro
grammer connector and the 16 pin front frame half of the
front/back frame connector. Insert 36 pin programmer con
nectors' beveled edges on the right-hand side (front view ) .

The 16-pin connector is inserted into the programmer con
nector bracket which is part of the flux shifter assembly. See
Fig. 2-4. Insert this connector so that the Number 1 pin is
towards the breaker's top, right-hand side.
Route the harness under the flux shifter base. Attach the har
ness to this base using the wire keeper provided.
Install the programmer harness as shown in Fig. 2-4. Include
the flux shifter leads with this harness.
Before installing the programmer bracket to the mounting
bracket, the flux shifter leads must be inserted into the pro
grammer connector. These leads are color-coded RED and
WHITE. The required connector pins are factory installed on
the leads. Insert the RED lead into Pin Number 32 and the
WHITE lead into Pin Number 28. Insert the pins until they
snap into place. Verify that the pins are fully inserted by
comparing them with the other pins.
Assemble the programmer bracket to the mounting bracket
as shown in Fig. 2-9.
