• 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.
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.
