1 Preface
Do not use unshielded cable for control wiring.
Failure to comply may cause electrical interference resulting in poor system performance.
Use shielded, twisted-pair wires and ground the shield to the ground terminal of the converter.
Do not modify the circuitry of the converter and the filter module.
Failure to comply could result in damage to the converter and will void warranty.
Yaskawa is not responsible for any modification of the product made by the user. This product must not be modified.
Check all the wiring to ensure that all connections are correct after installing the converter and connecting any
other devices.
Failure to comply could result in damage to the converter.
To get the full performance life out of the electrolytic capacitors and circuit relays, refrain from switching the converter
power supply off and on more than once every 30 minutes.
If a fuse is open or equipment for residual current monitoring/detection (RCM/RCD) is tripped, check the
wiring and the selection of the peripheral devices.
Contact your supplier if the cause cannot be identified after checking the above.
Do not restart the converter or immediately operate the peripheral devices if a fuse is open or an RCD is
tripped.
Check the wiring and the selection of peripheral devices to identify the cause.
Contact your supplier before restarting the converter or the peripheral devices if the cause cannot be identified.
Connect the converters to power supply transformers on a 1:1 basis and use independent grounds.
If devices, such as office equipment, that is sensitive to noise are installed in the same location, connect them while
observing the grounding standards for each device, separate the ground wires, and use independent grounds or noise
filters to prevent noise from entering the devices through the ground wire.
Do not expose the converter to halogen group disinfectants.
Failure to comply may cause damage to the electrical components in the converter.
Do not pack the converter in wooden materials that have been fumigated or sterilized.
Do not sterilize the entire package after the product is packed.
Precautions for CE Low Voltage Directive Compliance
This converter has been tested according to European standard IEC/EN 61800-5-1:2007, and it fully complies with the
Low Voltage Directive.
Do not use converter in areas with pollution degree 2 and overvoltage category III in accordance with IEC/EN 60664.
Ground the neutral point of the main power supply for 400 V Class converters.
