9.
Remove the lifting bar and or chains.
10.
Check for alignment of the optional Programmer disconnect on the left side in the compartment.
(It is fragile and will break if not properly aligned).
11.
Push the breaker into the compartment slowly while observing the programmer disconnect mating
and watching for the alignment of the secondary disconnects and opening of the optional shutter. A
compartment interlock rod in the right front will ride over a cam and drop into position in the
Disconnect position.
12.
When fully installed to the DISCONNECT position, the racking cams will stop on the racking pins in the
compartment and the breaker will be ready to rack in.
13.
Remove the racking tool.
(Figure 15
) from the storage location on the breaker front panel and extend
the torque bar from inside the handle.
14.
Use a blade-type screwdriver in the slot or rack-out-lock of the breaker
(Figure 16)
, and turn it
clockwise (to the right) so that the racking handle shutter opens.
15.
While turning the screwdriver to the right with the shutter open, insert the racking tool in the handle
insertion hole so that it engages with the racking mechanism, and remove the screwdriver
(Figure
16).
16.
Rotating clockwise ~37 turns racks the circuit breaker all the way into the compartment.
17.
As the breaker approaches the TEST position, a spring charging motor or undervoltage release if
installed may operate. (~ 9 racking turns).
18.
Continue rotating the racking handle clockwise until the position indicator first shows TEST; then
CONNECTED.
19.
When approaching the CONNECTED position, more torque for turning the racking handle is normal
as the primary finger clusters engage with the primary bus stabs.
20.
At the end of 37 to 37-1/2 rotations, the breaker is in its maximum travel position. At this point the
primary disconnect fingers have completely engaged with the primary bus stabs.
21.
Remove and store the racking handle in its storage location.
