Start-up Procedure
Testing Contactor Operation
The contactor must be tested without any applied medium voltage. This
should be done for initial startup and after any maintenance is performed. This
test power supply should be within the IntelliVAC™ Vacuum Contactor
Controller specifications (
). CPT on the cart is not energized
when the contactor is in the test/withdrawn position.
Connect an appropriate power cord to the power receptacle in the low voltage
compartment (
Figure 5
).

It is possible to open the MV door while the cart is in the test/withdrawn
position and the earthing switch is closed. The shutter behind the cart in the
MV compartment should be closed under this situation. This should be
confirmed after opening the MV door.
If the MV door cannot be opened smoothly, the shutter is not completely shut
off or the earthing switch is not completely closed.
ATTENTION:
Always perform the power lockout procedure before servicing
equipment. Failure to do so may result in severe burns, injury or death.
ATTENTION:
The following procedure requires racking the contactor cart to
its test position. To avoid potential of shock hazards, disconnect and lockout
incoming power before proceeding. Failure to lockout incoming power will
result in a live bus cell. Once the shutter between power cell and bus cell is
open, it may cause severe burns, injury or death. Rockwell Automation does
not assume any responsibility for injuries to personnel who have not
completed the following safety procedure prior to servicing the equipment.
