Power Lock-out Procedure
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 dissipate 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 (see
Figure 46 ).
d. Move the control switch to the TEST position.

ATTENTION: Always perform the Power Lock-out procedure before servicing
the equipment. Failure to do so may result in severe burns, injury or death.
ATTENTION: 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.
