Rockwell Automation 7000L PowerFlex Medium Voltage AC Drive (C Frame) - Classic Control - Manual (Page 247)

4-42 Commissioning
7000L-UM300I-EN-P – June 2013 7000 “C” Frame
Three Phase Input / Single Phase Input
This configuration has two sources of control power:
• Three phase control power for cooling system operation and
drive control
• Single-phase control power to operate the Interface, I/O and
additional auxiliaries.
Similar to the three-phase configuration, the input power for the
cooling system and control must be verified at the primary of DS.
However, the second source of control power must also be verified
against the prints at Circuit Breaker 1 (Labeled CB1 on the Electrical
Schematics).
If the ratings match the designation on the electrical schematic, it is
acceptable to apply control power to the drive by closing CB1 and
DS. Take necessary measures to rectify the control power levels in
the event that they do not meet the design specifications.
Power Supply Tests
The variety of components installed within the PowerFlex “C”
Frame drive require a versatile control distribution design. As a
result there are many power supplies incorporated within the drive
design. The following section describes how to verify that all power
supplies installed within the drive are functioning as designed.
Circuit Board Healthy Lights
Once all sources of control power have been verified and proven to
be within specified levels, close the low voltage input breaker (CB1)
and Disconnect Switch (DI); doing so will apply control power to the
drive.
Observe the healthy lights on all drive control boards to ensure that
the unit has passed all power-up self-tests. The following table
identifies the LEDs that should be illuminated, assuming the drive
passes all self-tests and is in a ready state:
