Troubleshooting and Error Codes
!
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 located 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: This drive contains ESD (Electrostatic
Discharge) sensitive parts and assemblies. Static control
precautions are required when installing, testing, servicing or
repairing this assembly. Component damage may result if ESD
control procedures are not followed. If you are not familiar with
static control procedures, reference A-B publication 8000-4.5.2,
“Guarding Against Electrostatic Damage” or any other
applicable ESD protection handbook.
!
ATTENTION: Only qualified personnel familiar with high
power PowerFlex 700S and 700H 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: To avoid an electric shock hazard, verify that all
input power has been removed from the drive and the voltage on
the bus capacitors has discharged completely before servicing.
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: Potentially fatal voltages may result from
improper usage of an oscilloscope and other test equipment. The
oscilloscope chassis may be at a potentially fatal voltage if not
properly grounded. If an oscilloscope is used to measure high
voltage waveforms, use only a dual channel oscilloscope in the
differential mode with X 100, isolated probes. It is recommended
that the oscilloscope be used in the A minus B Quasi-differential
mode with the oscilloscope chassis correctly grounded to an
earth ground.
!
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.
