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.
