CHAPTER 3 - BASIC CONFIGURATION3.1 Connection of peripheral devices to the inverterThe following devices are required to operate the inverter. Proper peripheral devices must beselected and correct connections made to ensure proper operation. An incorrectly applied orinstalled inverter can result in system malfunction or reduction in product life as well as componentdamage. You must read and understand this manual thoroughly before proceeding.AC Source SupplyUse the power supply within thepermissible range of inverter input powerrating (Refer to Page 13-1).MCCB or Earthleakage circuitbreaker (ELB)Select circuit breakers with care. A largeinrush current may flow in the inverter atpower on.Magnetic ContactorInstall it if necessary. When installed, donot use it for the purpose of starting orstopping. Otherwise, it could lead toreduction in product life.AC and DCReactors notice1The AC reactors must be used when thepower factor is to be improved or theinverter is installed near a large powersupply system (more than 10 times ofinverter capacity and wiring distancewithin 10m).Installation andwiringTo operate the inverter with highperformance for a long time, install theinverter in a proper place in the correctdirection and with proper clearances.Incorrect terminal wiring could result inthe equipment damage.To motorDo not connect a power factor capacitor,surge suppressor or radio noise filter tothe output side of the inverter.Notice1) Terminal block for DC reactor is composed in the morethan 11kw capacity3-1
