Safety Precautions

In addition to the precautions listed throughout this manual, please read and understand the following statements

regarding hazards associated with AC servo development system.

ATTENTION: The ground potential of the IRMCS2033 system is biased to a negative DC

bus voltage potential. When measuring voltage waveform by oscilloscope, the scope ground

needs to be isolated. Failure to do so may result in personal injury or death.

Darkened display LEDs is not an indication that capacitors have discharged to safe voltage

levels.

!

ATTENTION: The IRMCS2033 system contains dc bus capacitors which take time to

discharge after removal of main supply. Before working on 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 is 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 surface temperatures of the drive may become hot, which may cause

injury.
