Table 1 Precautions
Attention: The ground potential of the EVAL-M1-IM231-A 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-IM231-A 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-IM231-A 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
