4. Inside the compartment, check the contact areas on each primary disconnect bar or cluster of
fingers for foreign matter that may have accumulated. Clean those areas if necessary with a clean,
lint-free rag and isopropyl alcohol or acetone.
5. Be sure to apply a thin film of electrical grease (red, D50H47) to the contact areas for better
electrical connections inside the compartment.
After removing the existing breaker from the compartment, you now need to install the AKD-5 cassette
in the AKD-5 compartment or enclosure.
Install Position Switch Actuator—AK25 Breaker
Installing the position switch actuator needs to be done before the cassette is racked into the
compartment. Steps of installation of the position switch actuator are as follows.
1. Place the retrofit EntelliGuard ACB cassette assembly for AK25 on an elevated surface, such as a
table, mounting the position switch actuator assembly on to the base plate.
Sufficient space should be available at the bottom of the cassette and the mounting table so as to
provide easy access for inserting the 3-pin bracket from the bottom.
2. Unpack the position switch actuator assembly and mount it as shown in the exploded view
( Figure 11 ).

3. Insert the 3-pin bracket from the bottom of the base of the cassette assembly such that the 2 pins
are within the longer slot and the single pin goes inside the smaller slot of the plate.
4. Place the L-bracket from the top of the cassette assembly such that the pins from the bottom 3
pin plate get inserted into the top plate.
5. Secure the connecting by fastening the nuts provided in the actuator kit along with the washers.
