19bASIc SAFETY INSTrUcTIONS1.5 Start-up and operationThe drive converter must not be started until it is determined that the installation com-plies with the machine directive; Account is to be taken of EN 60204-1.WArNING Software protection and programming !Hazards caused by unintentional behavior of the drive!► Check especially during initial start-up or replacement of the driveconverter if parameterization is compatible to application.► Securing a unit solely with software-supported functions is not suf-ficient. It is imperative to install external protective measures (e.g.limit switch) that are independent of the drive converter.► Secure motors against automatic restart.cAUTION High temperatures at heat sink and coolant!burning of the skin!► Cover hot surfaces safe-to-touch.► Before working let the unit cool down.► Before touching, check the surface and cooling water lines.► If necessary, attach warning signs on the system.• During operation, all covers and doors shall be kept closed.• Use only approved accessories for this device.• Never touch terminals, busbars or cable ends.Observe the following instructions if the drive converter formore than one year was not in operation before start-up.ti_format_capacitors_0400_0001_gbr.pdfSwitching at the outputSwitching between motor and drive converter is prohibited for single drives during op-eration as this may trigger the protection gear of the device. Function speed search mustbe activated if switching can not be avoided. Control release may only be triggered afterclosing the motor contactor (e.g. by switching the control release).Connecting and disconnecting is permissible with multiple motor drives if at least 1 mo-tor is running during the switch-over process. The drive converter must be dimensionedto the occurring starting currents.The speed search function must be activated if the motor is still running during a restartof the drive converter (mains on) (e.g. due to large rotating masses).
