Always install this device to protect the wiring of the inverter
and peripheral devices.
Install this device to provide an operation interlock.
When using the DBR unit, always install this device to protect
the DBR. (Refer to Fig. 2-4.)
If the capacity of the inverter's power supply transformer
exceeds 10 times the inverter unit capacity, always install this
device to protect the inverter. (Balance with power supply) This
is also effective in improving the power factor of the inverter
input and in suppressing the current high harmonics. The power
factor will be approx. 0.9.
Install this device to improve the power factor of the inverter
input.
This is also effective in creating a balance with the power
supply as the ACL. The power factor will be approx. 0.9.
This device suppresses the electromagnetic noise generated by
the inverter.
The electromagnetic noise is the radiation of electromagnetic
waves in the radio frequency bands and that conveyed to the
power supply wires. Mounting of this device is recommended
for creating a balance with the peripheral devices of the
inverter.
This is used when the motor is to be stopped with dynamic
braking.
