before trying to install,operate,or maintain it.The following specialmessages may appear throughout this documentation or on the equipment to warnof potential hazards or to call attention to information that clarifies or simplifies aprocedure.The addition of this symbol to a Danger or Warning safety labelindicates that an electrical hazard exists,which will result in personalinjury if the instructions are not followed.This is the safety alert symbol.It is used to alert you to potentialpersonal injury hazards.Obey all safety messages that follow thissymbol to avoid possible injury or death.A DANGERDANGER indicates an imminently hazardous situation which,if not avoided,will result in death or serious injury.A WARNINGWARNING indicates a potentially hazardous situation which,if not avoided,canresult in death or serious injury.EIO000000036210/20107CAUTIONCAUTION indicates a potentially hazardous situation which,if not avoided,canresult in minor or moderate injury.CAUTIONCAUTION,used without the safety alert symbol,indicates a potentiallyhazardous situation which,if not avoided,can result in equipment damagePLEASE NOTEElectrical equipment should be installed,operated,serviced,and maintained only byqualified personnel.No responsibility is assumed by Schneider Electric for anyconsequences arising out of the use of this material.A qualified person is one who has skills and knowledge related to the constructionand operation of electrical equipment and the installation,and has received safetytraining to recognize and avoid the hazards

functions,provide a means toachieve a safe state during and after a path failure.Examples of critical controlfunctions are emergency stop and overtravel stop,power outage and restart.Separate or redundant control paths must be provided for critical controlfunctions.System control paths may include munication links.Consideration must begiven to the implications of unanticipated transmission delays or failures of thelink..Observe all accident prevention regulations and local safety guidelines.1Each implementation of this equipment must be individually and thoroughlytested for proper operation before being placed into service.Failure to follow these instructions can result in death,serious injury,orequipment damage.10E目IO00000003621020101 For additional information,refer to NEMA
