- Page 4 WARNING Only qualified personnel shall carry out wiring work. Otherwise, there is a danger of electric shock and/or fire. Implement wiring after checking that the power supply is off. Otherwise, there is a danger of electric shock and/or injury. Be sure not to touch the inside and terminal of the option board while the inverter is energized. Otherwise, there is a danger of electric shock and/or injury.
- Page 5 CAUTION Do not allow substance such as cutting waste, sputtering of welding, waste of iron, wire and dust etc. to come into contact with the unit. There is a fire risk. Inverter main body and option board must be fixed tightly with the screw of the belonging. There is a fear of contact defectiveness.
