Limits in purpose
This inverter is used for controlling speeds of three-phase induction motors in general industrial use.
Safety precautions
The inverter cannot be used in any device that would present danger to the human body or from which
malfunction or error in operation would present a direct threat to human life (nuclear power control
device, aviation and space flight control device, traffic device, life support or operation system, safety
device, etc.). If the inverter is to be used for any special purpose, first get in touch with the supplier.
This product was manufactured under the strictest quality controls but if it is to be used in critical
equipment, for example, equipment in which errors in malfunctioning signal output system would cause
a major accident, safety devices must be installed on the equipment.
Do not use the inverter for loads other than those of properly applied three-phase induction motors in
general industrial use. (Use in other than properly applied three-phase induction motors may cause an
accident.)
