Install Position Switch Actuator-Ak25 Breaker - ABB EntelliGuard AKD-5 Installation Manual

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.
