Safety precautions The items described in these instructions and on the inverter itself are very important so that you can use the inverter safely prevent injury to yourself and other people around you as well as prevent damage to property in the area. Thoroughly familiarize yourself with the symbols and indications shown below and then continue to read the manual.
Page 3 ■General operation • Never disassemble, modify or repair. This can result in electric shock, fire and injury. For repairs, call your sales agency. Disassembly prohibited • Never remove the front cover when power is on or open door if enclosed in a cabinet. The unit contains many high voltage parts and contact with them will result in electric shock.
Page 4 Operation cannot be stopped immediately by the inverter alone, thus risking an accident or injury. • All options used must be those specified by Toshiba. The use of any other option may result in an accident. 　　 Warning •...
Page 5 • Electrical construction work must be done by a qualified expert. Connection of input power by someone who does not have that expert knowledge may result in fire or electric shock. • Connect output terminals (motor side) correctly. Mandatory If the phase sequence is incorrect, the motor will operate in reverse and that may result in injury.

Page 19 Loads that generate negative torque When combined with loads that generate negative torque the protection for overvoltage and overcurrent on the inverter will go into operation and may cause a trip. For this kind of situation, you must install a dynamic braking resistor, etc. that complies with the load conditions. Motor with brake If a motor with brake is connected directly to the output side of the inverter, the brake will not release because voltage at startup is low.
Page 20 Circuit interrupting when two or more inverters are used on the same power line. MCCB1 There is no fuse in the inverter'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).

Page 103: Emc Directive
A machine which consists of an inverter and a motor is an object of CE marking. The EMC directive includes the emission section and the immunity section. VF-NC1 can conform to EMC directive by means of installing the recommended EMI noise filter to the input side, and wiring properly.
Page 104 9.1.3 Compliance with EMC directive 9.1.3.1 The model, noise filter inside (1) Single-phase 200V class : VFNC1S-2002PL to 2022PL The above mentioned models install EMI noise filter inside. So the conducted and radiated noise can be reduced, optional EMI noise filters are not needed. (The additional noise filter should be installed, when more effective reduction is required.) (2) The main cables such as input to the EMI filter and output of the inverter and the signal cables should be shielded, then cable length should be wired as short as possible.
Page 105 Shielded cable 9.1.3.2 The models without EMI filters (1) Shingle-phase 100V class : VFNC1-1001P to 1007P Three-phase 200V class : VFNC1-2001P to 2022P Shingle-phase 200V class : VFNC1S-2002P to 2022P This subsection explains what measures must be taken to satisfy the EMC directive. Insert a recommended EMI filter (Table 2) on the input side of the inverter to reduce radiation and transmission noises.
