Class 1 Light-emitting Diode Product
ATTENTION: To avoid an electric shock hazard, verify that the voltage on
the bus capacitors has discharged before servicing.
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. If an oscilloscope is used
to measure high-voltage waveforms, use only a dual channel oscilloscope in
the differential mode with X 100 probes. It is recommended that the
oscilloscope is used in the A minus B Quasi-differential mode and the
oscilloscope chassis is grounded to an earth ground.
ATTENTION: Always perform Power Lockout procedure before servicing
equipment. Verify with a hot stick or appropriate voltage measuring device
that all circuits are voltage free. Failure to do so may result in severe burns,
injury, or death.
ATTENTION: Servicing energized Medium Voltage Motor Control Equipment
can be hazardous. Severe injury or death can result from electrical shock,
bump, or unintended actuation of controlled equipment. Recommended
practice is to disconnect and lockout control equipment from power
sources, and release stored energy, if present.For countries following NEMA
standards, refer to National Fire Protection Association Standard No.
NFPA70E, Part II and (as applicable) OSHA rules for Control of Hazardous
Energy Sources (Lockout/Tagout) and OSHA Electrical Safety Related Work
Practices safety related work practices, including procedural requirements
for lockout/tagout, and appropriate work practices, personnel qualifications
and training requirements, where it is not feasible to de-energize and
lockout or tagout electric circuits and equipment before working on or near
exposed circuit parts.For countries following IEC standards, refer to local
codes and regulations.
ATTENTION: Only qualified personnel with the correct PPE (Personal
Protective Equipment) should service the equipment. Be sure to follow the
safety procedures and local regulations to disconnect the high voltage. After
waiting for 15 minutes, open the cabinet door and verify the absence of
medium voltage on the input, output, and power cell terminals with a high-
voltage detector that is properly rated for the line and motor voltages. All
status indicator lights on the power cells must be off and the drive be
grounded with portable grounding cables on the input and output before
servicing. Failure to follow the safety procedures can result in severe injury
or death.
ATTENTION: Use suitable personal protective equipment (PPE) per local
codes or regulations. Failure to do so may result in severe burns, injury, or
death.
ATTENTION: This drive contains ESD (Electrostatic Discharge) sensitive
parts and assemblies. Static control precautions are required when you
install, test, service, or repair this assembly. Component damage can result
if ESD control procedures are not followed.
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.
