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 EntelliGuard R Retrofill breaker on the rails (fig. 22) to the disconnect position of 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.
