E65820629-11 9. Measures to satisfy standards39• The input withstand rating is obtained with heat calculation. If the fuse is installed to a circuit withlarger input withstand rating, a reactor should be installed so that the input withstand rating should bereduced below this level.• Output interrupt rating varies depending on the type of integral solid state short circuit. Install the fuseaccording to the NEC standard, local standard and type of installation.• Use a fuse of Cooper Bussmann or Mersen.• Be sure to use rod crimp-style terminals for the grounding terminals of the heat sink and metal plateof the inverter.9. 2. 4 Overload protectionThe overload protection levels are below,HD rating: 150%-1minute, 180%-2s (Frame size A1~A6)150%-1minute, 165%-2s (Frame size A7, A8)ND rating: 120%-1minute, 135%-2s (All frame sizes)For the rated current, refer to the name plate.9. 2. 5 Motor thermal protectionTo use the electronic thermal function of this inverter for motor thermal protection, set parametersaccording to the motor specifications applied. For details, refer to [5. 2. 5].When operating multiple motors with one inverter, install overload relay for each motor.9. 2. 6 Motor integrated PTC thermal protectionFor details, refer to [6. 30. 19].9. 2. 7 OtherContact your Toshiba distributer or Toshiba sales representative (see the back cover of this manual), ifyou need the hard copy (paper) of CD-ROM.For details, refer to “VF-AS3 Safety function manual" (E6582068).9. 3 Compliance with safety standards
