Racking-Lock Bracket-Initial Tasks - ABB EntelliGuard AKD-5 Installation Manual

AK50 retrofits must be installed on the rear side, right-side sheet of the AK50 retrofill cassette.
9. Place the cassette on a work table.
The cassette should be positioned such that there is enough overhang of its side to insert the
position switch actuator assembly in the bottom of the cassette. Alternately, the installation can
also be done by placing the cassette assembly on the telescopic rails of the AKD5 compartment,
being retrofitted.
10. To install the position switch actuator, slide the assembly up from the bottom of the cassette.
When inserted, flip the position switch.
11. Line up the holes on the cassette side sheet with the holes provided on the actuator assembly.
12. Fasten the 3 M6 bolts and 6mm washers provided with the actuator assembly to the three holes
on the cassette side sheet. Two holes are placed on the side and one hole on the rear of the
cassette assembly.
The position switch actuator on the cassette is now installed and ready to be activated as soon as
the breaker is racked into the compartment.
13. Mount the cassette assembly on the rails of the AKD-5 LVS and rack the cassette into the
compartment.
Note: As the EntelliGuard R breaker is racked into the cassette, and the position indicator window reads
"connected" the retrofill Position Switch actuator should activate the compartment mounted position
switch in the AKD-5 LVS.
