16 Safety instructions Fiber optic cables 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 equipment malfunctionand damage to the fiber optic cables:• Handle the fiber optic cables with care. When unplugging optic cables, always grabthe connector, not the cable itself. Do not touch the ends of the fibers with bare handsas the fiber is extremely sensitive to dirt. The minimum allowed bend radius is 35 mm(1.4 in.).WARNING! Ignoring the following instructions can cause damage to the printedcircuit boards:• The printed circuit boards contain components sensitive to electrostatic discharge.Wear a grounding wrist band when handling the boards. Do not touch the boardsunnecessarily.WARNING! Ignoring the following instructions can cause physical injury ordeath, or damage to the equipment:• Before adjusting the drive and putting it into service, make sure that the motor and alldriven equipment are suitable for operation throughout the speed range provided bythe drive. The drive can be adjusted to operate the motor at speeds above and belowthe speed provided by connecting the motor directly to the power line.• Do not activate any automatic fault reset functions of the drive control program ifdangerous situations can occur. When activated, these functions will reset the driveand resume operation after a fault.• Do not control the motor with an AC contactor or disconnecting device(disconnecting means); instead, use the control panel keys and , orcommands via the I/O board of the drive. The maximum allowed number of chargingcycles of the DC capacitors 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 will startimmediately after an input voltage break or fault reset unless the drive is configuredfor 3-wire (a pulse) start/stop.• When the control location is not set to local, the stop key on the control panel will notstop the drive.
