Safety Precautions
addition precautions listed throughout this manual, please read understand following statements regarding hazards associated with development system.
ATTENTION: ground potential IRMCS3041 system biased negative voltage potential. When measuring voltage waveform oscilloscope, scope ground needs isolated. Failure result personal injury death. Darkened display LEDs indication that capacitors have discharged safe voltage levels.
ATTENTION: IRMCS3041 system contains capacitors which take time discharge after removal main supply. Before working drive system, wait three minutes capacitors discharge safe voltage levels. Failure result personal injury death. Darkened display LEDs indication that capacitors have discharged safe voltage levels.
ATTENTION: Only personnel familiar with drive associated machinery should plan implement installation, start-up, subsequent maintenance system. Failure comply result personal injury and/or equipment damage.
ATTENTION: surface temperatures drive become hot, which cause injury.

ATTENTION: IRMCS3041 system contains (Electrostatic Discharge) sensitive parts assemblies. Static control precautions required when installing, testing, servicing repairing this assembly. Component damage result control procedures followed. familiar with static control procedures, reference applicable protection handbook guideline.
ATTENTION: incorrectly applied installed drive result component damage reduction product life. Wiring application errors such undersizing motor, supplying incorrect inadequate supply, excessive ambient temperatures result system malfunction.
ATTENTION: Remove lock power from drive before disconnect reconnect wires perform service. Wait three minutes after removing power discharge voltage. attempt service drive until voltage discharged zero. Failure result bodily injury death.
ATTENTION: connect power factor correction capacitors drive output terminals Failure result equipment damage bodily injury.
ATTENTION: IRMCS3041 system includes field-weakening control function. However, drive trip occurs field-weakening operation, excessive over-voltage will result. Users should take necessary precautions protect against over-voltage. Failure result equipment damage bodily injury.
