Safety Information
Read and followall safetyinstructions in this manual precisely to avoid unsafe operating
conditions, property damage, personal injury, or death.
Safety symbols in this manual
Indicates an imminently hazardoussituation which,if not avoided, will resultin severe injury or
death.
Indicates a potentially hazardous situation which, if not avoided, could result in injury or death.
Indicates a potentiallyhazardous situation that, if not avoided, could result in minor injury or
propertydamage.
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 high voltage terminalsor charging area to
the external environment may result in an electric shock. Do not remove any covers or
touch theinternal circuit boards (PCBs) or electrical contacts on the product when the
power is on orduring operation. Doing so mayresultin serious injury, death, or serious
propertydamage.
•Do not open the cover of the equipment even when the powersupply to the inverter has
been turned off unless it is necessary formaintenance or regular inspection. Opening the
covermay resultin an electric shock even when the powersupplyis off.
•The equipment may hold charge long after the power supply has been turned off.Use a
multi-meter to make sure that there is no voltage before working on the inverter, motor or
motor cable.
•Supply earthing system: TT,TN, not suitable for corner-earthed systems
•This equipment must be grounded for safe and properoperation.
•Do not supply power to a faultyinverter. If you find that theinverteris 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.

iii
Safety Information
•Do not allowforeign objects, such as screws, metal chips, debris, water, or oil to getinside
the inverter.Allowing foreign objects inside the invertermaycause 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 notmodify theinterior workingsof the inverter. Doingso will void the warranty.
•The inverter is designed for 3-phase motor operation. Do not use the inverter to operate a
single phase motor.
•Do not place heavy objects on top of electric cables.Doingso may damage the cableand
result in an electric shock.
Note
Maximum allowed prospective short-circuit current at the input power connection is defined
in IEC 60439-1 as 100 kA. LSLV-H100 is suitable for use in a circuit capable of delivering
not more than 100kA RMS at the drive’s maximum rated voltage, depending on the
selected MCCB. RMS symmetrical amperes for recommended MCCB are the following
table.
Remarque
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. Selon le MCCB
sélectionné, la série LSLV-H100 peut être utilisée sur des circuits pouvant fournir un
courant RMS symétrique de 100 kAmaximum en ampères à la tension nominale
maximale du variateur. Le tableau suivant indique le MCCB recommandé selon le courant
RMS symétrique en ampères.
