Install or Insert AKD6 Retrofill
After the existing breaker is removed and the retrofill breaker is wired to match the
compartment, it can be installed in the AKD-6 switchgear.
Verify that the breaker is in the disconnected, switched-off position before mounting it
on the rails.
1. While rotating the lever (away from the cubicle) at the end of each rail, which unlocks the
inner rail, pull both the rail assemblies outwards to their fully extended positions.
2. The entire inner housing and front door must also be extended fully outward ~ 4.5”.
3. Use a suitable lifting device and AKR lifting bar. This might require a two-man effort: one
to carefully and slowly operate the lift and the other to guide the breaker into the
switchgear rail slots.
4. Make sure that the lifting bar is secured and locked in placed on the breaker.
5. Check that the retrofill is free from obstruction inside the compartment.
6. When the breaker is lined up with the compartment, raise the breaker only slightly
higher than the compartment floor, keeping it at slight angle.

7. Keep the breaker steady. Continue to guide the breaker, while checking both sides and
underneath, so that both sets of pins can be lowered and lined up easily with the rails
slots.
8. Place retrofit
Retrofill breaker on the rails (fig. 22) to the disconnect position of
Emax2
the legacy breaker. (Note that the pins must line up with the slots on the rails.)
9. Once the breaker rests on the rails at all 4 pins, unhook the lifting bar and move the
hoisting apparatus out of the way
