(Table 7-2.)Always install this device to protect the wiring of the inverterand peripheral devices.Magneticcontactor (MC)Select a device thatmatches the inverterrating. (Table 7-2.)Install this device to provide an operation interlock.When using the DBR unit, always install this device to protectthe DBR. (Refer to Fig. 2-4.)Stand-alone optionsACL ACR-• • • •(Refer to Table 7-2.)If the capacity of the inverter's power supply transformerexceeds 10 times the inverter unit capacity, always install thisdevice to protect the inverter. (Balance with power supply) Thisis also effective in improving the power factor of the inverterinput and in suppressing the current high harmonics. The powerfactor will be approx. 0.9.DCL DCR-• • • •(Refer to Table 7-2.)Install this device to improve the power factor of the inverterinput.This is also effective in creating a balance with the powersupply as the ACL. The power factor will be approx. 0.9.Noise filter PR-• • • •(Refer to Table 7-2.)This device suppresses the electromagnetic noise generated bythe inverter.The electromagnetic noise is the radiation of electromagneticwaves in the radio frequency bands and that conveyed to thepower supply wires. Mounting of this device is recommendedfor creating a balance with the peripheral devices of theinverter.DBR unit U2KV23DBU-• •(Refer to Table 7-2.) This is used when the motor is to be stopped with dynamicbraking.
