Preface

General Precautions

ATTENTION: To avoid an electric shock hazard, verify that the voltage on the bus
capacitors has discharged completely before servicing. Check the DC bus voltage
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: To guard against personal injury and or equipment damage caused
by an ARC Flash, the user needs to identify the ARC Flash requirements per NFPA
70E.

ATTENTION: The PowerFlex Active Front End contains electrostatic discharge
(ESD) sensitive parts and assemblies that can be damaged if you do not follow ESD
control procedures. Static control precautions are required when installing,
testing, servicing, or repairing this unit. If you are unfamiliar with static control
procedures, see Guarding Against Electrostatic Damage, publication 8000-4.5.2, or
any other applicable ESD protection handbook.

ATTENTION: An incorrectly applied or installed PowerFlex Active Front End can
result in component damage or a reduction in product life. Wiring or application
errors such as, undersizing the motor, incorrect or inadequate AC supply, or
excessive ambient temperatures can result in malfunction of the system.

ATTENTION: Only qualified personnel familiar with adjustable frequency AC
drives and associated machinery should plan or implement the installation,
startup, and subsequent maintenance of the system. Failure to comply can result
in personal injury and/or equipment damage.
