【正文】 Attach warning labelsShown here are examples of warning labels to prevent, in advance, accidents in relation to inverters, motors and other equipment.If the inverter has been programmed for autorestart function after momentary power failure or retry function, place warning labels in a place where they can be easily seen and read.If the inverter has been programmed for restart sequence of momentary power failure, place warning labels in a place where they can be easily seen and read.(Example of warning label)A Warning LH: p哪ammedDo not go near motors and equipment.Motors and equipment that have stopped temporarily after momentary power failure will restart suddenly after recovery.If the retry function has been selected, place warning labels in a location where they can be easily seen and read.(Example of warning label)A Wing for ret「y)Do not go near motors and equipment.Motors and equipment that have stopped temporarily after an alarm will restart suddenly after the specified time has6Read Check purchased productBefore using the product you have purchased, check to make sure that it is exactly what you ordered.Use an inverter that conforms to the specifications of power supply and threephase induction motor being used. If the inverter being used does not conform to those specifications, not only will the threephase induction motor not rotate correctly, but it may cause serious accidents through overheating and fire.Inverter type Power supply Rated output current and capacity/ Applicable motor label Contents of the product code■■■inn_in/Name plateSF3EOdrINVERTERSF3212A75 AIC 5000A INPUT OUTPUT U(V) 3PH 200/240 3PH F(Hz) 50/60 （A) Serial No.Motor Protective Device Class 10Made in JAPANHere is explained the type and form written on the label Type FormModel nameSF320aSeriesNumber of power phaseThree phase 200V class Single phase 200V class Single phase 10OV classApplicable motor capacityA10A20A4〇A751A52A2Special specification codeWarning : Always shut power off first then check the ratings label of inverter held in a cabinet.Cu71 lb in / 0A1 Name and function of each part Operation keypad panelMonitor keySwitches among operation, setting and status monitor modes.Input main circuit terminal blockUsed to connect a power source.RUN lampBlinks while the inverter is in operation.Every pressing of this key while the RUN key lamp is lit will cause a slowdown stop.Pressing this key while the inverter trip reset the inverter.Frequency adjusting knob (potentiometer)Allows you to adjust theoperation frequency whenthe inverter is placed in amode in which thepotentiometer can be used toenter operation mands.rtiaBLiSF32Q.DC main circuit terminal blockTerminals for connecting a DC reactor or a DC busSF3212A2Q| %i：rOutput main circuit terminal block：V■ P1 P(+) N() SU/T1 V/T2 \WTr^ Used to connect a motor.A2[Front panel 1]Charge lampIndicates that high voltage is still present within the inverter.

If this happens, operate with the output decreased from rated load.If you want to run continuously low speed operations at rated torque, please use the AF motor made especially for Sumitomo Heavy Industries inverter. When operating in conjunction with a AF motor, you must change the inverter39。\171。s reference current is set to the inverter39。s mechanical strength limits and the bearing limits so that you should inquire about such operation.Method of lubricating load mechanisms.Operating an oillubricated reduction gear and gear motor in the lowspeed areas will worsen the lubricating effect. Check to find out about operable gearing area.Low loads and low inertia loadsThe motor may demonstrate instability such as abnormal vibrations or overcurrent trips at light loads of 50 percent or under of the load percentage, or when the load39。s main circuits.In circuit configuration 1, the brake is turned on and off through MC2 and MC3. If the circuit is configured in some other way, the overcurrent trip may be activated because of the locked rotor current when the brake goes into operation. Circuit configuration 2 uses lowspeed signal FRQ/DRV to turn on and off the brake. Turning the brake on and off with a lowspeed signal may be better in such applications as elevators. Please confer with us before designing the system. InvertersProtecting inverters from overcurrentThe inverter has an overcurrent protection function. However because the programmed current level is set to the inverter39。s main circuit. Thus, as the diagram above shows, when more than one inverter is used on the same power line, you must select interupting characteristics so that only the MCCB2 will trip and the MCCB1 will not trip when a short occurs in the inverter (INV1). When you cannot select the proper characteristics install a circuit interrupting fuse between the MCCB2 and the INV1.■ DisposalIf an inverter is no longer usable, dispose of it as industrial waste. What to do about leak current/tv WarningCurrent may leak through the inverter39。s value is affected by the carrier frequency
