Safety instructions19Printed circuit boardsSafe start-up and operationGeneral safetyThese warnings are intended for all who plan the operation of the drive or operatethe drive.Permanent magnet motor drivesWARNING! Do not run the motor over the rated speed. Motor overspeed leads toovervoltage which may damage or explode the capacitors in the intermediate circuitof the drive.WARNING! Ignoring the following instructions can cause damage to the printedcircuit boards:• Wear a grounding wrist band when handling the boards. Do not touch theboards unnecessarily. The printed circuit boards contain components sensitiveto electrostatic discharge.WARNING! Ignoring the following instructions can cause physical injury or death,or damage to the equipment:• Before adjusting the drive and putting it into service, make sure that the motorand all driven equipment are suitable for operation throughout the speed rangeprovided by the drive. The drive can be adjusted to operate the motor atspeeds above and below the speed provided by connecting the motor directlyto the power line.• Do not activate any automatic fault reset functions of the drive control programif dangerous situations can occur. When activated, these functions will resetthe drive and resume operation after a fault.• Do not control the motor with an AC contactor or disconnecting device;instead, use the control panel keys and , or commands via the I/Oboard of the drive. The maximum allowed number of charging cycles of the DCcapacitors, ie, power-ups by applying power, is five in ten minutes.Note:• If an external source for start command is selected and it is ON, the drive willstart immediately after an input voltage break or fault reset unless the drive isconfigured for 3-wire (a pulse) start/stop.• When the control location is not set to local, the stop key on the control panelwill not stop the drive.
