Component Test Procedures
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 all power to the
PowerFlex® Active Front End has been removed before you perform any
service or repairs.
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: Hot surfaces can cause severe burns. Do not touch the heatsink
surface during operation of the PowerFlex Active Front End. After you
disconnect power, allow time for cooling.
ATTENTION: Hazard of permanent eye damage exists when using optical
transmission equipment. This product emits intense light and invisible
radiation. Do not look into fiber-optic ports or fiber-optic cable connectors.
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 to
install, test, service, or repair this assembly. 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.
