Installation and wiring
• Turn the inverter's power OFF and wait for at least five minutes. Further, check that the DC link bus
voltage between the P (+) and N (-) terminals is lower than 25 VDC.
• Qualified electricians should carry out wiring.
Otherwise, electric shock could occur.
• Do not use the product that is damaged or lacking parts.
Doing so could cause a fire, accident, or injury.
• Prevent lint, paper fibers, sawdust, dust, metallic chips, or other foreign materials from getting into
the inverter and the option.
Otherwise, a fire or an accident might result.
• Incorrect handling in installation/removal jobs could cause a failure.
A failure might result.
• Noise may be emitted from the inverter, motor and wires. Implement appropriate measure to prevent
the nearby sensors and devices from malfunctioning due to such noise.
Otherwise, an accident could occur.
Operation
• Be sure to install the terminal block cover, front cover of the inverter and option terminal cover before
turning the inverter's power ON. Do not remove the covers while power is applied.
Otherwise electric shock could occur.
• Do not operate switches with wet hands.
Doing so could cause electric shock.
• If you set the function codes wrongly or without completely understanding FRENIC-Multi Instruction
Manual (INR-SI47-1094-E) and the FRENIC-Multi User's Manual (MEH457), the motor may rotate
with a torque or at a speed not permitted for the machine. Confirm and adjust the setting of the
function codes before running the inverter.
Otherwise, an accident could occur.
Maintenance and inspection, and parts replacement
• Turn the inverter's power OFF and wait for at least five minutes before starting inspection. Further,
check that the DC link bus voltage between the P (+) and N (-) terminals is lower than 25 VDC.
Otherwise, electric shock could occur.
• Maintenance, inspection, and parts replacement should be made only by qualified persons.
• Take off the watch, rings and other metallic objects before starting work.
• Use insulated tools.
Otherwise, electric shock or injuries could occur.
