 Safety Warnings
• Do not attempt to modify or alter the drive in any way not explained in this manual.
Failure to comply could result in death or serious injury.
YASKAWA is not responsible for any modification of the product made by the user. This
product must not be modified.
• Do not touch any terminals before the capacitors have fully discharged.
Failure to comply could result in death or serious injury.
Before wiring terminals, 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 50 VDC. To prevent electric shock, wait at least five
minutes after all indicators are off and measure the DC bus voltage level to confirm safe level.
• Do not allow unqualified personnel to use equipment.
Failure to comply could result in death or serious injury.
Maintenance, inspection, and replacement of parts must be performed only by authorized
personnel familiar with installation, adjustment, and maintenance of AC drives.
• Do not remove covers or touch circuit boards while the power is on.
Failure to comply could result in death or serious injury.
• Make sure the protective earthing conductor complies with technical standards and local
safety regulations.
The leakage current of this drive exceeds 3.5 mA. Therefore, according to IEC 61800-5-1,
automatic power supply interruption in case of discontinuity of the protective earthing
conductor must be provided or a protective earthing conductor with a cross section of at least
10 mm 2 (Cu) or 16 mm
• Use appropriate equipment for residual current monitoring/detection (RCM/RCD).
This drive can cause a residual current with a DC component in the protective earthing
conductor. Where a residual current operated protective or monitoring device is used for
protection in case of direct or indirect contact, always use an RCM or RCD of type B according
to IEC 60755.
• Always ground the motor-side grounding terminal.
Improper equipment grounding could result in death or serious injury by contacting the motor
case.
