Safety precautions
1 Safety precautions
In addition to the precautions listed throughout this manual, please read and understand the following
statements regarding hazards associated with development systems.
Table 1 Precautions
Attention: The ground potential of the EVAL-M1-36-84A system is biased to a negative DC
bus voltage potential. When measuring voltage waveform by oscilloscope, the
scope’s ground needs to be isolated. Failure to do so may result in personal
injury or death. Darkened display LEDs are not an indication that capacitors
have discharged to safe voltage levels.
Attention: EVAL-M1-36-84A system contains DC bus capacitors which take time to discharge
after removal of the main supply. Before working on the drive system, wait
three minutes for capacitors to discharge to safe voltage levels. Failure to do so
may result in personal injury or death. Darkened display LEDs are not an
indication that capacitors have discharged to safe voltage levels.
Attention: Only personnel familiar with the drive 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: The surfaces of the drive may become hot, which may cause injury.
Attention: EVAL-M1-36-84A system contains parts and assemblies sensitive to Electrostatic
Discharge (ESD). Electrostatic 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
electrostatic control procedures, refer to applicable ESD protection handbooks
and guidelines.
Attention: A drive, incorrectly applied or installed, can result in component damage or
reduction in product lifetime. Wiring or application errors such as under sizing
the motor, supplying an incorrect or inadequate AC supply or excessive ambient
temperatures may result in system malfunction.
Attention: Remove and lock out power from the drive before you disconnect or reconnect
wires or perform service. Wait three minutes after removing power to discharge
the bus capacitors. Do not attempt to service the drive until the bus capacitors
have discharged to zero. Failure to do so may result in personal injury or death.
