Position Switch Kit for Retrofill CB

DEH-41530 02/12

Figure 5

, below, shows the AK50 position switch actuator assembly in an exploded view. The position switch actuator

for the AK50 is a field-fit type of assembly and is assembled on the retrofill cassette before inserting the cassette into
the compartment of the AKD-5.
It needs to be ensured that the cassette is in the “disconnected” state. This can be verified by checking the racking
position status in the window located at the right side window, located on the frame of the AK50 retrofil cassette,
placed at the front. The position-switch actuator kit for the AKD5-AK50 retrofits needs to be installed on the bottom
rear side of the right side sheet of the AK50 retrofit cassette.
This installation can be done by placing the cassette on a work table. The cassette should be placed such that there
is enough overhang of the side where there’s room to insert the position switch actuator components from under-
neath. Alternately, the installation can also be achieved by placing the cassette assembly on the retrofit AK50, that is,
on the telescopic rails of the AKD5 compartment that is being retrofit.

Installation

1. Once the access for installing the position switch actuator is achieved, slide the assembly up from the bottom

of the cassette. When inserted, the plate is placed on the outside of the cassette side sheet and the movable
flaps are on the inside.

2. Line up the holes on the cassette side sheet with the holes on the actuator assembly.
3. Fasten the three M6-bolts and 6-mm 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 back of the cassette assembly.

4. Check that the position switch actuator on the cassette is now installed and ready for use as the breaker is

being racked into the compartment.

5. Mount the cassette assembly on the rails of the AK50 cabinet in the AKD-5 and rack the cassette into the

compartment of the AKD-5 LVS.

Note: While racking the EntelliGuard ACB
breaker into the cassette, as you rack in the
breaker, the position indicator window reads
“connected”. This position indicator means that
the retrofit system has activated the existing
position switch in the LVS.
