Preface
General Precautions for Class
1 Light-emitting Diode
Product
ATTENTION: Hazard of permanent eye damage exists when using optical
transmission equipment. This product emits intense light and invisible
radiation. Do not look into module ports or fiber-optic cable connectors.
ATTENTION: The sheet metal cover and mounting screws on the ASIC Board
that is on the power structure are energized at (-) DC bus potential high
voltage. Risk of electrical shock, injury, or death exists if someone comes into
contact with the assembly.
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 voltagemust
be zero for all three measurements.
ATTENTION: Potentially fatal voltages can result from improper usage of an
oscilloscope and other test equipment.The oscilloscope chassis can be at a
potentially fatal voltage if not properly grounded. Use high-voltage
differential voltage probes for all voltage measurements with the oscilloscope
chassis that is correctly grounded to an earth ground.
ATTENTION: The PowerFlex Active FrontEnd 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 to install, test,
service, or repair this unit. If you are unfamiliar with static control procedures,
see Guarding Against ElectrostaticDamage, publication 8000-4.5.2, or any
other applicable ESD protection handbook.
ATTENTION: An incorrectly applied or installed PowerFlex ActiveFront 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 can plan or implement the installation, start-
up,and subsequentmaintenanceof the system.Failure to comply canresultin
personal injury and/or equipment damage.
