Precautions for Safe Use

Precautions for Safe Use
Installation and Storage
Do not store or use the product in the following places.
• Locations subject to direct sunlight.
• Locations subject to ambient temperature exceeding the specifications.
• Locations subject to relative humidity exceeding the specifications.
• Locations subject to condensation due to severe temperature fluctuations.
• Locations subject to corrosive or flammable gases.
• Locations subject to exposure to combustibles.
• Locations subject to dust (especially iron dust) or salts.
• Locations subject to exposure to water, oil, or chemicals.
• Locations subject to direct shock or vibration.
Transportation, Installation, and Wiring
• Do not drop or apply strong impact on the product. Doing so may result in damaged parts or malfunction.
• Do not hold by the front cover and terminal cover, but hold by the cooling fins during transportation.
• Confirm that the rated input voltage of the inverter is the same as AC power supply voltage.
• Do not connect an AC power supply voltage to the control input/output terminals. Doing so may result
in damage to the product.
• Be sure to tighten the screws on the terminal block securely. Wiring work must be done after install-
ing the unit body.
• Do not connect any load other than a three-phase inductive motor to the U, V, and W output terminals.
• Take sufficient shielding measures when using the product in the following locations. Not doing so
may result in damage to the product.
Locations subject to static electricity or other forms of noise.
Locations subject to strong magnetic fields.
Locations close to power lines.
• If a parameter is set incorrectly when starting up, adjusting, maintaining, or replacing, an unexpected
operation may occur. Perform the operation after enough confirmation.
• When using the DriveProgramming, check that program is downloaded normally before starting oper-
ation.

Operation and Adjustment

• Be sure to confirm the permissible range of motors and machines before operation because the
inverter speed can be changed easily from low to high.
• Provide a separate holding brake if necessary.
• If the DriveProgramming stops during multi-function output, the output status is held. Take safety pre-
cautions such as stopping peripheral devices.
• Even when the inverter power is turned off, the counter-electromotive force occurs while the PM
motor rotates, which may result in electric shock.
Do not remove the terminal block cover of the inverter until the PM motor stops.
• Be sure to confirm the RUN signal is turned off before resetting the alarm because the machine may
abruptly start.
