IRMCS2031

Safety Precautions

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

regarding hazards associated with AC servo development system.

ATTENTION: Some ground potential of the IRMCS2031 system is biased to a negative DC

bus voltage potential and kept high voltage potential while power is on. 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 IRMCS2031 system contains high voltage capacitors which take time to

discharge after removal of main supply. Before working on drive system, ensure isolation of

mains supply from line inputs [R, S, T]. 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.

ATTENTION: The IRMCS2031 system contains ESD (Electrostatic Discharge) sensitive

parts and assemblies. Static control precautions are required when installing, testing,

servicing or repairing this assembly. Component damage may result if ESD control
