ABB AKR30S-800A Installation And Maintenance Manual page 46

Programmer disconnect assemblies are available in two configurations, namely:
e 12-pin configuration. If the legacy LVS has a 12-pin programmer disconnect in use,
the same can be used with the Retrofill breaker. In this case, only the breaker side
programmer disconnect assembly on the breaker needs to be installed. The
numbers for the programmer disconnects are mentioned below.
e 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.

3. If applicable, remove the existing compartment side programmer disconnect assembly.
The programmer disconnect assembly must be removed, if:
e A 9-pin manual programmer disconnect assembly is installed in the cabinet as a
result of conversion kit.

MicroVersaTrip ~1979-1984.
e Customer chooses to replace a 12-pin configuration with a 19-pin configuration to
Add RELT
4. Before uninstalling the existing programmer disconnect assembly, verify that the wiring
details match the wiring numbers. Any changes or deviations need to be noted for use
while installing the new programmer disconnect.
5. Check that the compartment is de-energized and is safe to work in; and that the legacy
breaker has been removed from the cabinet.
6. Disconnect the wires connecting the terminal block to the compartment Programmer
disconnect assembly. See Figure 51.
7. If the customer has chosen to install a 19-pin programmer disconnect assembly,
Replacing A 12-pin programmer disconnect assembly, the terminal block mounted on
the compartment needs to be removed as well. This can be achieved by unfastening the
two screws securing the terminal block with the side wall of the compartment.
8. Unfasten the four bolts included that the hold the programmer disconnect assembly on
the wall of the compartment to remove the compartment-side programmer disconnect
