Safety Precautions

The precautions and general installation requirements provided in the PowerFlex 700 Frame 7-10 Installation Instructions (publication 20B-IN014) and the PowerFlex 700 User Manual (publication 20B-UM002) must be followed in addition to those included here.
ATTENTION: To avoid an electric shock hazard, ensure that all power has been removed before proceeding. In addition, before servicing, verify that the voltage on the bus capacitors has discharged. Check the DC bus voltage at the Power Terminal Block by measuring between the DC+ & DC– terminals, between the DC+ terminal and the chassis, and between the DC– terminal and the chassis. The voltage must be zero for all three measurements.
ATTENTION: Remove power before making or breaking cable connections. When you remove or insert a cable connector with power applied, an electrical arc may occur. An electrical arc can cause personal injury or property damage by:
· sending an erroneous signal to your system’s field devices, causing unintended machine motion.
· causing an explosion in a hazardous environment.
ATTENTION: Electrical arcing causes excessive wear to contacts on both the module and its mating connector. Worn contacts may create electrical resistance.
1. Turn off and lock out input power. Wait five minutes.
2. Verify that there is no voltage at the drive’s input power terminals.
3. Check the DC bus voltage at the Power Terminal Block by measuring
between the DC+ and DC– terminals, between the DC+ terminal and the chassis, and between the DC– terminal and the chassis. The voltage must be zero for all three measurements.

ATTENTION: This assembly contains parts and sub-assemblies that are sensitive to electrostatic discharge. Static control precautions are required when servicing this assembly. Component damage may result if you ignore electrostatic discharge control procedures. If you are not familiar with static control procedures, reference Allen-Bradley Publication 8000-4.5.2 Guarding Against Electrostatic Damage, or any other applicable ESD protection handbook.

Preface
ATTENTION: The information in this publication is merely a guide for
proper installation. Rockwell Automation, Inc. cannot assume responsibility for the compliance or the noncompliance to any code (national, local, or otherwise) for the proper installation of this drive or associated equipment. A hazard of personal injury and/or equipment damage exists if codes are ignored.
ATTENTION: Only qualified personnel familiar with adjustable frequency AC drives and associated machinery should plan or implement the installation, start-up, and subsequent maintenance of the system. Failure to comply may result in personal injury and/or equipment damage.
ATTENTION: HOT surfaces can cause severe burns. Do not touch the heatsink surface during operation of the drive. After disconnecting power, allow time for cooling.
ATTENTION: Replace all protective shields before applying power to the drive. Failure to replace protective shields may result in death or serious injury.

Preface

Important Initial Steps

Read and follow these statements before performing any service on the drive.
· Read and follow the precautions in Safety Precautions on page 9
· Identify components to be replaced using the figures in Component
Diagrams and Torque Specs on page 13.
· Remove protective shields only as necessary.
· Before disconnecting any wire or cable, verify that it is labeled. Also, when
removing components, note hardware type and location.
· When torquing any fasteners, use a colored marker or torque seal to mark each screw after torquing so you know when all are done and to indicate signs of any subsequent tampering.
· Refer to the product installation documentation for startup and other instructions after servicing.

Torque Sequence
ATTENTION: When mounting components to a drive’s heat sink,
component fastener torque sequences and tolerances are crucial to component-to-heat sink heat dissipation.
Components can be damaged if initial tightening procedure is not performed to specification.
The following illustrates initial and final tightening sequences for components fastened to a heat sink using two, four, and six screws. Initial torque is 1/3 (33%) of final torque, except six-point mountings, which require 0.7 N•m (6 lb•in) The numeric illustration labels are for your assistance. Drive components do not carry these labels.
