Component Definition and Maintenance
This section provides an overview of the control components and cabling of your
PowerFlex 7000 “B” Frame drive. It also details a number of regular or recurring
maintenance tasks that will keep your drive in peak operating condition.
The following illustrations identify the control components and cabling of your
drives. Where appropriate, separate diagrams and instructions are available for
both the heat sink and the heat pipe “B” Frame models.
For information regarding power wiring and cabling connections (as might be
necessary for routine maintenance) refer to the PowerFlex 7000 “B” Frame
Installation Manual (
7000-IN007_-EN-P ).
Control Power Off Tests Perform the following checks before applying control power to the drive.
Rockwell Automation recommends that you complete these checks in the
sequence they are presented here.
Interlocking
When the input contactor option is purchased, a key interlock is provided to
prevent access to the medium voltage compartments of the drive unless the input
isolation switch is locked in the open position.
Where the input switching device is provided by others, Rockwell Automation
will provide a key interlock on the medium voltage compartment of the drive,
and a matching interlock for installation by others on the upstream device. The
interlock shall be installed in a manner that ensures the power to the drive is off
and the drive is electrically isolated whenever the key is freed.
Although Key interlocks shipped with all medium voltage equipment are aligned
in the factory, they often move out of position during shipping or are often
misaligned when the cabinet is set down on an uneven floor. The following
instructions will assist the field engineers in quickly and accurately aligning the
deadbolt key interlock with its counterpart.
IMPORTANT This section is also available in the PowerFlex “B” Frame Commissioning Guide
(
7000-IN006_-EN-P ); refer to that document for additional information on
drive testing.
