Chapter 1 Introduction
On-site Verification of Electrical System One-line Diagram
Once all documentation has been reviewed, an on-site inspection of the drive is
required. Identify the physical locations of the connections to the drive using Tag
Identification names or numbers from the one-line diagram and Rockwell
Automation Electrical Drawings.
All customer power and control wiring required for the drive line-up installation
has been identified on the Rockwell Automation Electrical Drawings by a dashed
line.
Installation of all external power cabling and control wiring interfacing with the
drive is completed by the customer or their electrical contractor. Verify that this
wiring is installed correctly and meets electrical voltage and current capacity
requirements. Trace the power cables point-to-point from the input circuit
breaker to the drive, and from the drive to the motor using the Electrical
Drawings as a reference for proper drive power cable termination locations. Any
discrepancy between the physical installation and the Electrical Drawings of the
following items should be reviewed prior to commissioning the drive:
• Medium voltage power cabling in from the input circuit breaker to drive
• Medium voltage power cabling out from drive to motor
• Low Voltage control power cables from LV MCC or circuit breaker to
drive
• Ground connection from system ground to drive
• Control signal wires and communication cables from remote DCS/PLC
or other remote device to drive
• Electrical safety interlock/control wiring from the drive to the input
circuit breaker
ATTENTION: Make sure the medium voltage input circuit breaker feeding the
drive is locked out and tagged out. Make sure the LV circuit breaker feeding
control power to the drive is locked out and tagged out. Make sure the drive is
de-energized before conducting the drive inspection process.
ATTENTION: Do not change wiring or remove terminal wiring.
