Points for HandlingFollow this manual and precautions when handling the inverter.Incorrect handling could lead to inhibited operation or a drop operatinglife. In the worst case, the inverter could be damaged.Power supply Use within + 10%, -15% of the tolerable inputvoltage range, and within 㫧5% of the tolerableinput frequency range.Circuit breakerMCCBSize a breaker from the selection table on page 17.MagnetcontactorMCA magnet contactor is not required in normaluse. If installed, do not start or stop the inverterwith the magnet contactor.Power factorimprovementreactorConnect this when the power factor must beimproved.Input noisefilterConnect this when noise to the peripheraldevices is a problem.N䊶FInverter The ambient temperature is the most importantfactor for the installation site. Make sure that thetolerable value is not exceeded.(See page 9 and 11)Thermal relayfor open phaseprotectionThe thermal component built into the inverter isused to protect against overloads. Use an openphase protection thermal relay for open phaseprotection.Motor 3-phase induction motor.8
