User’s Manual

•SV-iS7 is the official name for the iS7 series inverters.
•This operation manual is intended for users with basic knowledge of electricity and electric
devices.
•Keep this manual near the product for future reference whenever setting change, maintenance
or service is required.
•Ensure that the field operators and service engineers can easily access this manual.
•For detailed information about the optional extension boards, including the specifications and

Safety Information
Safety Information
Read and follow all safety instructions in this manual precisely to avoid unsafe operating
conditions, property damage, personal injury, or death.
Safety symbols in this manual
Indicates an imminently hazardous situation which, if not avoided, will result in severe injury or
death.
Indicates a potentially hazardous situation which, if not avoided, could result in injury or death.
Indicates a potentially hazardous situation which, if not avoided, could result in minor injury or
property damage.
Safety information
•Do not open the cover of the equipment while it is on or operating. Likewise, do not operate the
inverter while the cover is open. Exposure of the high voltage terminals or the charging area to
the external environment may result in an electric shock. Do not remove any covers or touch
the internal circuit boards (PCBs) or electrical contacts on the product when the power is on or
during operation. Doing so may result in serious injury, death, or serious property damage.
•Do not open the cover of the equipment, even when the power supply to the inverter has been
turned off, unless it is necessary for maintenance or regular inspection. Opening the cover may
result in an electric shock even when the power supply is off.
•The equipment may hold a charge long after the power supply has been turned off. Use a
multi-meter to make sure that the remaining voltage is below 30 VDC before working on the
inverter, motor, or motor cable.

iii
Safety Information
•This equipment must be grounded for safe and proper operation.
•Do not supply power to a faulty inverter. If you find that the inverter is faulty, disconnect the
power supply and have the inverter professionally repaired.
•The inverter becomes hot during operation. Avoid touching the inverter until it has cooled to
avoid burns.
•Do not allow foreign objects, such as screws, metal chips, debris, water, or oil, to get inside the
inverter. Allowing foreign objects inside the inverter may cause the inverter to malfunction or
result in a fire.
•Do not operate the inverter with wet hands. Doing so may result in electric shock.
•Do not modify the interior workings of the inverter. Doing so will void the warranty.
•Do not use cables with damages or cracks on the protective insulation when wiring the inverter.
Damaged insulation may cause misoperation, an electric shock or a fire.
•Do not place heavy objects on top of electric cables. Doing so may damage the cable and result
in an electric shock.

About This Manual
Note
[English]
The maximum allowed prospective short-circuit current at the input power connection is defined in
IEC 60439-1 as 100 kA. The drive is suitable for use in a circuit capable of delivering not more than
100 kA RMS at the drive’s maximum rated voltage, depending on the selected MCCB. RMS
symmetrical amperes for recommended MCCB are the following table.
[French]
Le courant maximum de court-circuit présumé autorisé au connecteur d’alimentation électrique est
défini dans la norme IEC 60439-1 comme égal à 100 kA. L’entraînement convient pour une utilisation
dans un circuit capable de délivrer pas plus de 100 kA RMS à la tension nominale maximale de
l’entraînement. Le tableau suivant indique le MCCB recommandé selon le courant RMS symétrique
en ampères.
