Before You Open the Power Cabinet
Consult the PowerFlex 750-Series Products with TotalFORCE Control Hardware Service Manual, publication 750- TG100 for the following information:
• How to remove power from the system • AC input and DC bus voltage testpoints • Provided lockout provisions
Power Module Handling
Power Module Removal Consult one the following publications for instructions on how to prepare power modules for removal:
• PowerFlex 750-Series Products with TotalFORCE Control Installation Instructions, publication 750-IN100 • PowerFlex 750-Series Products with TotalFORCE Control Hardware Service Manual, publication 750-TG100
ATTENTION: Only qualified personnel familiar with adjustable frequency AC drives and associated machinery can plan or implement the installation, startup, and subsequent maintenance of the system. Failure to comply can result in personal injury and/or equipment damage.
ATTENTION: Hazards of pinch point injury exist. Review all product labels and familiarize yourself with the potential pinch point hazards before you use the service ramp. Use caution when raising and lowering the ramp and when installing or removing the module. Do not place your hands or feet near pinch points during installation.
ATTENTION: Power modules have a high center of gravity and a tip- over hazard exists. To guard against death, serious personal injury, or equipment damage, do not subject the module to high rates of acceleration or deceleration while transporting. Do not push or pull above the points that are indicated on the module. ATTENTION: Two people are required when using the ramp to install or remove a power module.
IMPORTANT Take precautions when you move a module: • Only move a module a short distance to gain access to the
cabinet interior or to service the module. • Always use the service cart when transporting the module, see
the PowerFlex 750-Series Service Cart, publication 750-IN105. • Only use the service ramp on a smooth and level surface. • Maintain that the path for the power module is clear of debris
and obstacles. • Always move the power module slowly. • When moving the power module, stand at the sides of the
module.
This label, affixed to the module chassis, identifies the center of gravity.
Rockwell Automation Publication 750-IN108A-EN-P - February 2017 3
1. To disconnect the required wiring harnesses, fiber-optic cables, and power and ground connections, follow the instructions provided in the installation instructions (publication 750-IN100) or hardware service manual (publication 750-TG100).
2. Remove all debris, cabling, and obstructions from the front of the cabinet and the anticipated path of the module. Verify that all cables are secured away from the path of removal.
3. Insert the hinge of the ramp into the flange that is mounted into the floor at the front of the control cabinet. The ramp must be at an approximate 90° angle to have the hinge lock into the flange correctly.
4. With the hinge properly placed, lower the ramp to the floor and verify that it lays flat and is clear of debris. 5. To release the module, remove the upper and lower anchor bolts. 6. Align the ramp with the prepared module.
IMPORTANT Complete step 4 before you remove the bolts that anchor the power module to the cabinet floor. Be sure that the ramp is locked into the cabinet floor before you remove the anchor bolts.
IMPORTANT It is critical to have a level surface clear of debris and obstruction for service ramp usage.
ATTENTION: Power modules have a high center of gravity and a tip-over hazard exists. To guard against death, serious personal injury, or equipment damage, do not subject the module to high rates of acceleration or deceleration while transporting. Do not push or pull above the points that are indicated on the module.
Do not remove these anchor bolts until instructed to.

7. With two people, use the handle that is provided to move the module down the ramp.
8. Use the handle on the power module to extract the power module until all four wheels reach the floor.
9. Remove the service ramp so that the isle is clear to manipulate the service module.
Temporary Power Module Storage Use caution when handling power modules for service or for temporary storage. It is recommended to use the anti-tip module storage hardware, 20-750-MINV-ATIP, for stabilization during storage. See the PowerFlex 755TM Power and Filter Module Storage Hardware Installation Instructions, publication 750-IN106.
Choose a suitable storage location for the module: • The surrounding atmosphere must not contain volatile or corrosive
gas, vapors, or dust. • The surrounding atmosphere must not contain conductive pollution. • Surrounding air temperature is -40…+70 °C (-40…+158 °F). • Do not store modules in active isles and work areas. • Store modules on a smooth and level surface clear of debris and
obstacles. • Avoid sloped and rough surfaces.
ATTENTION: The module is heavy and gravity takes over as the module is removed.
IMPORTANT Always attach PowerFlex 755TM Power and LCL Module storage hardware that is shown at right to help stabilize LCL filter modules and power modules during storage.

IMPORTANT It is critical to have a level surface clear of debris and obstruction for optimal service ramp usage.
ATTENTION: Power modules have a high center of gravity and a tip-over hazard exists. To guard against death, serious personal injury, or equipment damage, do not subject the module to high rates of acceleration or deceleration while installing. Do not push or pull above the points that are indicated on the module. Do not use excessive force. Do not attempt to push the module with your feet. Always install module with two people.
ATTENTION: Hazards of pinch point injury exist when using service ramp. Review all product labels and familiarize yourself with the potential pinch point hazards before you install the service ramp. Use caution when raising and lowering the ramp and when installing the module. Do not place your hands or feet near pinch points during installation.

7. Use a steady motion, push the module up the ramp and into the control cabinet. The module is secured in the cabinet when a click is heard. The wheel guides on the ramp create proper alignment for the module to enter the cabinet.
8. To secure the module, insert the upper and lower anchor bolts. 9. To disconnect the required wiring harnesses, fiber-optic cables, and power and ground connections, follow the
instructions provided in the installation instructions (publication 750-IN100) or hardware service manual (publication 750-TG100).
Service Ramp Storage Recommendations Choose a suitable storage location for the ramp:
• The surrounding atmosphere must not contain volatile or corrosive gas, vapors, or dust. • The surrounding atmosphere must not contain conductive pollution. • Surrounding air temperature: -40…+70 °C (-40…+158 °F) • Relative humidity: 5…95% noncondensing. • Store ramp on a surface clear of debris and obstacles.
Service Ramp Maintenance Inspect the service ramp for damage or excessive wear before each use. Check for cracks, chips, deformation, or bent rails.

Introduction_Category Types
This tab summarizes Rockwell Automation Global Sales and Marketing preferred printing standards. It also provides guidance on whether a publication should be released as JIT (print on demand) or if it requires an RFQ for offset printing. Find your publication type in the first section below. Use the assigned Printing Category information to determine the standard print specifications for that document type. The Printing Categories are defined below the Publication Type section. Note there may be slightly different print specifications for the categories, depending on the region (EMEA or Americas). For more information on Global Sales and Marketing Printing Standards, see publication RA-CO004 in DocMan.

Just In Time (JIT) or Off Set (OS)?
Use these guidelines to determine if your publication should be JIT (just in time/print on demand) or if it would be more economical to print OS (offset/on a press). OS print jobs require an RFQ (Request For Quote) in US. If your job fits into the “Either” category, an RFQ is recommended, but not required. In the US, RA Strategic Sourcing will discourage or reject RFQs for jobs that fall within the JIT category. Guidelines differ for black & white and color printing, so be sure to check the correct tables.
