Maintenance 5-3
1512A-UM102B-EN-P – June 2013
Use suitable personal protective equipment (PPE)
per local codes or regulations. Failure to do so may
result in severe burns, injury or death.
Always perform the power lockout procedure before
servicing the equipment. Failure to do so may result
in severe burns, injury or death.
The following procedure requires moving the isolation
switch handle to the ON position. To avoid shock
hazards, disconnect and lock out incoming power
before proceeding with servicing the equipment.
Failure to lock out incoming power will result in a live power cell
once the isolation switch handle is in the ON position and 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.
1) Disconnect and lock out all feeder power supplies to the starter.
2) Move the isolation switch handle to the OFF position.
3) If the unit is equipped with power factor correction capacitors,
stored energy must be dissipated before entering the power cell.
Wait at least five minutes before entering the power cell or dissi-
pate the power using the following procedure:
a) Verify that the isolation switch handle is in the OFF position.
b) Open the low voltage door.
c) Connect the appropriate power supply (120 or 230V) into the
auxiliary control power circuit as shown on the electrical drawing.
d) Move the control switch to the TEST position.
