This chapter describes how to start up the PowerFlex 520-series drive. To
simplify drive setup, the most commonly programmed parameters are
organized in a single Basic Program Group.

1. Disconnect and lock out power to the machine.
2. Verify that AC line power at the disconnect device is within the rated
value of the drive.
3. If replacing a drive, verify the current drive’s catalog number. Verify all
options installed on the drive.
4. Verify that any digital control power is 24 volts.
5. Inspect grounding, wiring, connections, and environmental
compatibility.
6. Verify that the Sink (SNK)/Source (SRC) jumper is set to match your
control wiring scheme. See the PowerFlex 523 Control I/O Terminal
Block on page 37 and PowerFlex 525 Control I/O Terminal Block on
page 41 for location.
7. Wire I/O as required for the application.

IMPORTANT
Read the General Precautions on page 13 section before proceeding.
ATTENTION: Power must be applied to the drive to perform the following
start-up procedures. Some of the voltages present are at incoming line
potential. To avoid electric shock hazard or damage to equipment, only
qualified service personnel should perform the following procedure.
Thoroughly read and understand the procedure before beginning. If an
event does not occur while performing this procedure, Do Not Proceed.
Remove All Power including user supplied control voltages. User supplied
voltages may exist even when main AC power is not applied to the drive.
Correct the malfunction before continuing.
IMPORTANT
The default control scheme is Source (SRC). The Stop terminal is
jumpered to allow starting from the keypad or comms. If the control
scheme is changed to Sink (SNK), the jumper must be removed from I/O
Terminals 01 and 11 and installed between I/O Terminals 01 and 04.
