•
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.
Intended Use
Drives are intended for installation in electrical systems or machinery.
The Drives are designed and manufactured in accordance with applicable UL and cUL standards, and CE directives.
For use in the European Union, the installation in machinery and systems must conform to the following product stan-
dards of the Low Voltage Directive:
EN 50178: 1997-10, Electronic Equipment for Use in Power Installations
EN 60201-1: 1997-12 Machine Safety and Equipping with Electrical Devices
Part 1: General Requirements (IEC 60204-1:1997)
EN 61010: 1997-11
Safety Requirements for Information Technology Equipment
(IEC 950:1991 + A1:1992 + A2:1993 + A3:1995 + A4:1996, modified)
The G7 series Drives comply with the provisions of the Low Voltage Directive 73/23/EEC as amended by 93/68/EEC.
These Drives conform to the following standard: EN 50178: 1997-10.
Your supplier or Yaskawa representative must be contacted when using leakage current circuit breaker in conjunction
with frequency drives.
In certain systems it may be necessary to use additional monitoring and safety devices in compliance with the relevant
safety and accident prevention regulations. The frequency drive hardware must not be modified.
