Warnings and Cautions
This Section provides warnings and cautions pertinent to this product, that if
not heeded, may result in personal injury, fatality, or equipment damage.
Yaskawa is not responsible for consequences of ignoring these instructions.
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.

„ Read and understand this manual before installing, operating, or servicidriveng 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 personal injury.
„ Do not connect unapproved LC or RC interference suppression filters, capacitors, or overvoltage 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.
