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 which a 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.
When using inverters for critical equipment, even though the inverters are
manufactured under strict quality control always fit your equipment with safety
devices to prevent serious accident or loss should the inverter fail (such as failure
to issue an inverter trouble signal)
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.)
When the inverter is used to control the operation of a permanent magnet motor, a
combination test must be conducted in advance. For details on the test, contact
your supplier.
