DEH-41532 02/12

Description

The programmer disconnect consists of two assemblies, one mounted on the breaker side and the second mounted
on the cabinet. The breaker side assembly consists of the mounting bracket, plug assembly. The compartment side
assembly consists of the plug assembly mounted on spring loaded assembly that receives the breaker side plug.
Tools required: Spanner, Flat Head Screw driver, Wire stripper, Wire Cutter, Star type screw driver
Steps to assemble programmer disconnect assembly are as follows:

Identify Existing Programmer Disconnect (Compartment)

The existing programmer disconnect plugs used in AKD8 generation of the AKR breakers are provided on the right
side in case of AKR30/30H/50/50H/30L and on the left side for AKR30S retrofits.
Programmer disconnects are provided with legacy AKR breakers in AKD8 LVS. The breakers were equipped with the
following pin configurations depending on the application
• 9-pin configuration
• 12-pin configuration
• 24-pin configuration

Identify Programmer Disconnect Type to be Installed (with Kit)

The programmer disconnect assembly to be assembled depends on the type of breaker the retrofil is replacing.
These are as follows:

• AKR30/30H/50/50H/30L: In these switchgear, mount the programmer disconnect on the left side wall of the retrofil.

• AKR30S: In these switchgear, mount the programmer disconnect on the right side wall of the retrofil.

Programmer disconnect assemblies are available in two configurations for the Retrofill EntelliGuard ACB:
12-pin configuration: If the legacy LVS has a 12-pin programmer disconnect in use, it can be used with the Retrofill
EntelliGuard ACB. In this case, only the breaker side programmer disconnect assembly needs to be installed.
Programmer disconnects are itemized below.
19-pin configuration: If the legacy LVS doesn’t have a 12-pin programmer disconnect configuration, and the
customer chooses to install a programmer disconnect, then the 19-pin programmer disconnect assembly needs
to be installed in the compartment and the breaker.

Remove Existing Programmer Disconnect (Compartment)

The programmer disconnect assembly must be removed under these conditions:
• 9-pin programmer disconnect assembly is installed in cabinet.
• 24-pin programmer disconnect assembly is installed in cabinet.
• Customer chooses to replace a 12-pin configuration with a 19-pin configuration.
1. Before uninstalling the existing programmer disconnect assembly, make sure that the wiring details are checked

against the wiring numbers. Any changes or deviations need to be noted for use during installation of the new
programmer disconnect.

2. Check that the compartment is de-energized and is safe to work on and the existing breake, if present within the

cabinet, has been removed.

3. Disconnect the wires that connect the terminal block to the compartment programmer disconnect assembly.
