Startup Information See the PowerFlex 750-Series AC Drives with TotalFORCE Control Quick Start
for detailed startup The procedure in this Startup chapter is designed to guide
you through the 12 basic steps that are required to start up your PowerFlex®
750-Series product with TotalFORCE control for the first time for simple
applications.
CIP Security CIP Security™ is a standard, open-source communication mechanism that
helps to provide a secure data transport across an EtherNet/IP™ network. CIP
Security lets CIP™-connected devices authenticate each other before
transmitting and receiving data.
CIP Security uses the following security properties to help devices protect
themselves from malicious communication:
• Device Identity and Authentication
• Data Integrity and Authentication
• Data Confidentiality
Rockwell Automation uses the following products to implement CIP Security:
• FactoryTalk® Policy Manager software (includes FactoryTalk System
Services, version 6.20 or later)
• FactoryTalk Linx software, version 6.11 or later (lets workstation software
communicate securely using CIP Security)
• Studio 5000 Logix Designer® application, version 31.00.00 or later This
application is required to interface with CIP Security-enabled Logix
controllers. The minimum application version varies by controller
product family.

Apply and Remove Power The following procedures describe how to energize PowerFlex 755T products in
both stand-alone and in system installations.
755TL and TR Drives without 24V Auxiliary Power
This procedure applies to drives without 24V auxiliary power.
Energize
Energize the product in the following sequence:
1. Energize three-phase power (A).
2. Turn the fused disconnect handle (B) to the ‘On’ position.
De-energize
De-energize the product in the following sequence:
1. Turn the fused disconnect handle (B) to the ‘Off’ position.
2. De-energize three-phase power (A). This may not be needed.

Chapter 1 Overview
755TL and TR Drives with 24V Auxiliary Power
This procedure covers drives with 24V auxiliary power.
Energize
Energize the product in the following sequence:
1. Leave 24V auxiliary power (C) energized when the drive is not in
operation. This keeps up the control and communication.
2. Energize three-phase power (A).
3. Turn the fused disconnect switch (B) to the ‘On’ position.
4. After drive boots up, clear faults related to the three-phase outage.
De-energize
De-energize the product in the following sequence:
1. Turn the fused disconnect switch (B) to the ‘Off’ position.
2. De-energize three-phase power (A). This may not be needed.
Leave 24V auxiliary power (C) energized when the drive is not in operation.
IMPORTANT This procedure assumes that 24V auxiliary power was not removed when
the product was de-energized. If you are conducting an initial powerup,
or if 24V auxiliary power was removed, only apply 24V auxiliary power as
the final step in the Energize sequence.

Chapter 1 Overview
Systems with 755TM Bus Supplies and Common Bus Inverters
This procedure covers systems without 24V auxiliary power and without
separate 240V control power.
Bus supplies ordered with the –C1 Control Transformer option do not require
separate 240V control power.
Energize
Energize the product in the following sequence:
1. Leave the Control Power switches (E) for the Common Bus Inverters in
the ‘On’ position when the drive system is not in operation.
2. Leave the DC Precharge switches (F) for the Common Bus Inverters in
the ‘On’ position when the drive system is not in operation. This step is
not required for Common Bus Inverters without DC Precharge.
3. Energize three-phase power (A).
4. Turn the fused disconnect switch (B) to the ‘On’ position.
De-energize
De-energize the product in the following sequence:
1. Turn the fused disconnect switch (B) to the ‘Off’ position.
2. De-energize three-phase power (A). This may not be needed.
3. Leave the Control Power switches (E) for the Common Bus Inverters in
the ‘On’ position when the drive system is not in operation.
4. Leave the DC Precharge switches (F) for the Common Bus Inverters in
the ‘On’ position when the drive system is not in operation. This step is
not required for Common Bus Inverters without DC Precharge.
