Safety Information and Precautions
8) Voltage-sensitive device or capacitor on output side of the AC drive
Do not install the capacitor for improving power factor or lightning protection voltage-
sensitive resistor on the output side of the AC drive because the output of the AC drive
is PWM wave. Otherwise, the AC drive may suffer transient overcurrent or even be
damaged.
9) Contactor at the I/O terminal of the AC drive
When a contactor is installed between the input side of the AC drive and the power
supply, the AC drive must not be started or stopped by switching the contactor on or
off. If the AC drive has to be operated by the contactor, ensure that the time interval
between switching is at least one hour since frequent charge and discharge will shorten
the service life of the capacitor inside the AC drive.
When a contactor is installed between the output side of the AC drive and the motor,
do not turn off the contactor when the AC drive is active. Otherwise, modules inside the
AC drive may be damaged.
380 VAC
50 /60 Hz
Do not start /stop the AC drive by switching
the contactor on /off. If the AC drive has to
be operated by the contactor , ensure that
the time interval is at least one hour .
10) When external voltage is out of rated voltage range
The AC drive must not be used outside the allowable voltage range specified in this
manual. Otherwise, the AC drive's components may be damaged. If required, use a
corresponding voltage step-up or step-down device.
11) Prohibition of three-phase input changed into two-phase input
Do not change the three-phase input of the AC drive into two-phase input. Otherwise, a
fault will result or the AC drive will be damaged.
