2.1 Section Safety
NOTICE
Install vibration-proof rubber on the base of the motor or use the frequency jump function in the
drive to prevent specific frequencies that vibrate the motor.
Motor or system resonant vibration can occur in fixed speed machines that are converted to variable speed. Too
much vibration can cause damage to equipment.
You can use the drive with an explosion-proof motor, but the drive is not explosion-proof. Install
the drive only in the environment shown on the nameplate.
If you install the drive in a dangerous environment, it can cause damage to the drive.
Do not lift the drive with the covers removed.
If the drive does not have covers, you can easily cause damage to the internal parts of the drive.
