18 Safety instructions Printed circuit boardsSafe start-up and operation General safetyThese warnings are intended for all who plan the operation of the drive or operate thedrive.WARNING! Ignoring the following instructions can cause damage to theprinted circuit 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 ordeath, or damage to the equipment:• Before you connect voltage to the drive, make sure that the drive covers areon. Keep the covers on during the operation.• Before adjusting the drive and putting it into service, make sure that the motorand all driven equipment are suitable for operation throughout the speedrange provided 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.• The maximum number of drive power-ups is five in ten minutes. Too frequentpower-ups can damage the charging circuit of the DC capacitors.• Make sure that any safety circuits (for example, emergency stop and Safetorque off) are validated in start-up. See chapter Start-up for reference of thevalidation instructions.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.
