Safety
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:
Use suitable personal protective equipment (PPE) per local
codes or regulations. Failure to do so may result in severe burns, injury, or
death.
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:
These tasks require persons skilled in this type of detailed work.
Read and understand this manual thoroughly before commencing. Contact
Rockwell Automation with any questions or for clarification.
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 LED
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.
