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
d. Move the control switch to the TEST position.
