Warnings and Cautions
YASKAWA manufactures component parts that can be used in a wide variety of industrial applications. The selection and application of
YASKAWA products remain the responsibility of the equipment designer or end user. YASKAWA accepts no responsibility for the way its
products are incorporated into the final system design. Under no circumstances should any YASKAWA product be incorporated into any
product or design as the exclusive or sole safety control. Without exception, all controls should be designed to detect faults dynamically and
to fail safely under all circumstances. All products designed to incorporate a component part manufactured by YASKAWA must be supplied
to the end user with appropriate warnings and instructions as to that part's safe use and operation. Any warnings provided by YASKAWA
must be promptly provided to the end user. YASKAWA offers an express warranty only as to the quality of its products in conforming to
standards and specifications published in the YASKAWA manual. NO OTHER WARRANTY, EXPRESS OR IMPLIED, IS OFFERED.
YASKAWA assumes no liability for any personal injury, property damage, losses, or claims arising from misapplication of its products..
„ Read and understand this manual before installing, operating, or servicing this drive. All warnings, cautions, and instructions must be
followed. All activity must be performed by qualified personnel. The drive must be installed according to this manual and local codes.
„ Do not connect or disconnect wiring while the power is on. Do not remove covers or touch circuit boards while the power is on. Do not
remove or insert the digital operator while power is on.
„ Before servicing, disconnect all power to the equipment. The internal capacitor remains charged even after the power supply is turned
off. Status indicator LEDs and Digital Operator display will be extinguished when the DC bus voltage is below 50VDC. To prevent
electric shock, wait at least 5 minutes after all indicators are OFF and measure the DC bus voltage level to confirm that it is at a safe
level.
„ Do not perform a withstand voltage test on any part of the unit. This equipment uses sensitive devices and may be damaged by high
voltage.
„ The drive is not suitable for circuits capable of delivering more than the specified RMS symmetrical amperes. Install adequate branch
short circuit protection per applicable codes. Refer to the specification. Failure to do so may result in equipment damage and/or per-
sonal injury.
„ Do not connect unapproved LC or RC interference suppression filters, capacitors, or over voltage protection devices to the output of the
drive. Capacitors may generate peak currents that exceed drive specifications.
„ To avoid unnecessary fault displays, caused by contactors or output switches placed between drive and motor, auxiliary contacts must
be properly integrated into the control logic circuit.
„ YASKAWA is not responsible for any modification of the product made by the user, doing so will void the warranty. This product must
not be modified.
„ Verify that the rated voltage of the drive matches the voltage of the incoming power supply before applying power.
„ To meet CE directives, proper line filters and proper installation are required.
„ Some drawings in this manual may be shown with protective covers or shields removed, to describe details. These must be replaced
before operation.
„ Observe Electrostatic Discharge Procedures when handling the drive and drive components to prevent ESD damage.
„ The attached equipment may start unexpectedly upon application of power to the drive. Clear all personnel from the drive, motor and
machine area prior to applying power. Secure covers, couplings, shaft keys, machine beds and all safety equipment before energizing
the drive.
