Warnings and Cautions

WARNING

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 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. The charge indicator LED will extinguish when the DC bus voltage is below 50Vdc. To prevent electric shock, wait at least five minutes after all indicators are OFF and measure DC bus voltage level to confirm 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 suitable for circuits capable of delivering not more than 100,000 RMS symmetrical Amperes, 240Vac

maximum (200-240V Class) and 480Vac maximum (380-480V Class). Install adequate branch circuit short circuit protection per applicable codes. Failure to do so may result in equipment damage and/or personal injury. Refer to Appendix E for further details.

• Do not connect unapproved LC or RC interference suppression filters, capacitors, or overvoltage protection devices to the

output of the Drive. These devices may generate peak currents that exceed Drive specifications.

• To avoid unnecessary fault displays caused by contactors or output switches placed between Drive and motor, auxil-

iary 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 circuit boards to prevent ESD damage.

• The equipment may start unexpectedly upon application of power. Clear all personnel from the Drive, motor, and

machine area before applying power. Secure covers, couplings, shaft keys, and machine loads before energizing the Drive.

• Please do not connect or operate any equipment with visible damage or missing parts. The operating company is

responsible for any injuries or equipment damage resulting from failure to heed the warnings in this manual.

• In a clean location which is free from oil mist and dust.

• In an environment where metal shavings, oil, water, or other foreign materials do not get into the Drive.

• In a location free from radioactive materials and combustible materials (e.g. wood).

• In a location free from harmful gases and liquids.

• In a location free from excessive vibration.

• In a location free from chlorides

• In a location away from direct sunlight.

1-10

 Controlling the Ambient Temperature

To enhance the reliability of operation, the Drive should be installed in an environment free from extreme temperature variation. If the Drive is installed in an enclosure, use a cooling fan or air conditioner to maintain the internal air temperature below 113°

F (45°C).

 Protecting the Drive from Foreign Matter

During Drive installation and project construction, it is possible to have foreign matter such as metal shavings or wire clippings fall inside the Drive. To prevent foreign matter from falling into the Drive, place a temporary cover over the Drive.

Always remove the temporary cover from the Drive before start-up. Otherwise, ventilation will be reduced, causing the Drive to overheat.
