Precautions for Correct Use

Precautions for Correct Use
Installation
Mount the product vertically on a wall with the product's longer sides upright.
The material of the wall must be noninflammable such as a metal plate.
Restart Selection Function
• Do not come close to the machine when using the restart selection function (b001, b008) because
the machine may abruptly start when stopped by an alarm.
Deceleration Stop Function
Do not come close to the machine when selecting reset in Deceleration Stop Selection on Power Inter-
ruption (b050) because the machine may abruptly start after the power is turned on.
Operation Stop Command
• Provide a separate emergency stop switch because the STOP Key on the Operator is valid only
when function settings are performed.
• When checking a signal during the power supply and the voltage is erroneously applied to the control
input terminals, the motor may start abruptly. Be sure to confirm safety before checking a signal.

Motor Overload Protection

• For the motor overload protection, be sure to set the rated current of your motor to the Electronic
Thermal Level (b012/b212) and PM Motor Rated Current (H105).
Maintenance and Parts Replacement
• Inverters contain components and will operate properly only when each component operates nor-
mally. Some of the electrical components require maintenance depending on application conditions.
Periodic inspection and replacement are necessary to ensure proper long-term operation of invert-
ers. (Quoted from The Recommendation for Periodic Maintenance of a General-purpose Inverter
published by JEMA.)
• When a cooling fan reaches the end of its service life, replace it.
Product Disposal
Comply with the local ordinance and regulations when disposing of the product.
