Yaskawa D1000 Series Power Regenerative Converter - Manual (Page 19)

i.2 General Safety
YASKAWA ELECTRIC TOEP C710656 07C YASKAWA Power Regenerative Converter - D1000 Instruction Manual 19
Connecting an Advanced-phase Capacitor or Thyristor-controlled Device to the Power Supply
An advanced-phase capacitor is not required for the converter. Installing an advanced-phase capacitor will reduce the
power factor.
If an advanced-phase capacitor currently exists is in the same power supply system as the converter, install a series reactor
on the advanced-phase capacitor to prevent resonance with the converter.
If a device that generates voltage surge or voltage distortion, such as a thyristor-controlled DC drive or electromagnetic
mixer is installed in the same power supply system as the converter, consult with your Yaskawa representative or the
nearest Yaskawa sales office.
Countermeasures for EMC and High-frequency (Harmonic) Leakage Current
Although countermeasures are not required for harmonic currents, the same countermeasures for electrical interference
(EMC) and high-frequency (harmonic) leakage current are required as for a normal drive. If there are nearby devices that
are easily affected by electrical interference, use a reactor-type noise filter (e.g., zero phase reactor).
When installing an MCCB or GFCI at the power supply, use an MCCB or GFCI that is designed for a drive (i.e., one that
has countermeasures for high-frequency leakage current).
Compliance with Harmonic Suppression Guidelines
• Guidelines for harmonic suppression measures are applicable to consumers that receive power from a 6.6 kV or higher
system. For details, refer to the Harmonics Suppression Technical Guideline JEAG 9702-1995.
• With respect to the harmonic suppression guidelines, the converter is equivalent to a three-phase bridge that does not
generate harmonics (K
5
= 0), but the harmonic component is not completely zero.
Impact of Power Supply Distortion
Distorting the power supply voltage and connecting several devices in parallel to the same power supply will cause power
supply system harmonics to flow into the converter and increase the harmonic content.

AVERTISSMENT NPJT31470-1
Lire le manuel avant l'installation. Attendre 5 minutes après la coupure de l'alimentation, pour permettre la décharge des condensateurs. Pour répondre aux exigences , s assurer que le neutre soit relié à la terre, pour la série 400V. Après avoir déconnécte la protection entre le driver et le moteur, veuillez patienter 5 minutes avain d’effectuer une opération de montage ou de câblage du variateur.
Risque de décharge électrique.
Surfaces Chaudes Dessus et cotés du boitier Peuvent devenir chaud. Ne Pas toucher.
WARNING
Read manual before installing. Wait 5 minutes for capacitor discharge after disconnecting power supply. To conform to requirements, make sure to ground the supply neutral for 400V class. After opening the manual switch between the drive and motor, please wait 5 minutes before inspecting, performing maintenance or wiring the drive.
Risk of electric shock.
Hot surfaces Top and Side surfaces may become hot. Do not touch.
