• Operation is allowed only in compliance with thenational EMC regulations for the applicationconcerned.• See the VLT® ISD 410 Design Guide for informationregarding EMC-compliant installation of the servosystem.• Compliance with the limit values specified bynational regulations is the responsibility of theproducer of the plant, system or machine.• Compliance with the specifications, connectionconditions and installation conditions in thisinstruction manual is mandatory.• The safety regulations and safety provisions ofthe country in which the equipment is used mustbe observed.• Care must be taken to ensure that orderlyprotective earthing of the equipment, whichprotects the user against the supply voltage andprotects the power supply module againstoverload, is performed in accordance with localand national regulations.• Overload protection for the servomotor can beprogrammed using the master system. For moreinformation, see Programming in the VLT® ISD 410Design Guide.• Do not remove or replace the SD card on theencoder box during operation, otherwise thecontents of the SD card could be destroyed.Switch the encoder box off and wait 10 secondsbefore removing the SD card.WARNINGEARTHING HAZARDFor reasons of operator safety, the components of theservo system must be earthed correctly in accordance withnational or local electrical regulations and the informationin these operating instructions. The earth leakage currentis greater than 3.5 mA. Improper earthing of theservomotor may result in death or serious injury.Operational Safety• Safety-related applications are allowed only ifthey are explicitly and unambiguously mentionedin the VLT® ISD 410 Design Guide. Otherwise theyare not allowed.• All applications that can cause hazards to peopleor damage to property are safety-relatedapplications.• The stop functions implemented in the softwareof the master system do not interrupt the mainsvoltage supply to the power supply module andare therefore not allowed to be used as safetyswitches for the servo system.• The motor can be brought to a stop by asoftware command or a zero speed setpoint, butDC voltage remains present on the servomotorand/or mains voltage in the power supplymodule. If personal safety considerations (e.g. riskof personal injury caused by contact with movingmachine parts after an unintended start) make itnecessary to ensure that an unintended startcannot occur, these stop functions are notsufficient. In this case the servo system must bedetached from the mains network or a suitablestop function must be implemented.• When the servomotor is stopped, it may start upagain on its own if the circuitry of the servomotoris defective or after the elimination of atemporary overload, a problem with the supplyvoltage or a problem with the servomotor. Ifpersonal safety considerations (e.g. risk ofpersonal injury caused by contact with movingmachine parts after an unintentional start) makeit necessary to ensure that an unintended startcannot occur, the normal stop functions of theservomotor are not sufficient. In this case theservo system must be disconnected from themains network or a suitable stop function mustbe implemented.• The servomotor may start running unintentionallyduring parameter configuration or programming.If this can pose a risk to personal safety (e.g. riskof personal injury due to contact with movingmachine parts), unintended motor starting mustbe prevented, for example by using the Safe Stopfunction or by safe disconnection of theservomotors.• Do not disconnect the cables from theservomotor while the servo system is connectedto mains voltage. Ensure that the mains supply isdisconnected and the required waiting time haselapsed before disconnecting or connecting thehybrid cable or disconnecting cables from theconnection box and/or the power supply module.Safety VLT® ISD Power Supply Module Operating Instructions8 MG75H102 - VLT® is a registered Danfoss trademark33
