Page 24: Grounding Capacitor Switching Method
E6581386 1.3.3 Grounding capacitor switching method The inverter is grounded through a capacitor. The leakage current from the inverter can be reduced using the selector switch, switching bar or switching screw (depending on the model) on the main circuit terminal board. This switching device is used to detach the capacitor from the grounding circuit or to reduce its capacitance.

Caution Use an inverter that conforms to the specifications of power supply and three-phase induction motor being used.
Page 30 E6581386 Method of lubricating load mechanisms Operating an oil-lubricated reduction gear and gear motor in the low-speed areas will worsen the lubricating effect. Check with the manufacturer to find out about operable speed range. Low loads and low inertia loads The motor may demonstrate instability such as abnormal vibrations or overcurrent trips at light loads of 5% or under of the rated load, or when the load's moment of inertia is extremely small.
Page 31: Inverters
Circuit configuration 2 uses low-speed signal OUT1 to turn on and off the brake. Turning the brake on and off with a low-speed detection (OUT1 function) may be better in such applications as elevators. Please confer with contact your Toshiba distributor before designing the system. Measures to protect motors against surge voltages In a system in which a 400V-class inverter is used to control the operation of a motor, very high surge voltages may be produced.
Page 32: What To Do About The Leak Current
If the sensors and CRT are affected, it can be remedied by reducing the PWM carrier frequency described in 1 above, but if this cannot be remedied because of the increase in the motor's electric magnetic noise, please consult with contact your Toshiba. * Cautions for applying models with a built-in noise filter.
Page 33 E6581386 (2) Affects of leakage current across supply lines Thermal relay inverter Power supply Leakage current path across wires (1) Thermal relays The high frequency component of current leaking into electrostatic capacity between inverter output wires will increase the effective current values and make externally connected thermal relays operate improperly. If the motor cables are more than 50m long, external thermal relay may operate improperly with models having motors of low rated current, especially the 400V class low capacity (3.7kW or less) models, because the leakage current will be high in proportion to the motor rating.
Page 34: Installation
E6581386 1.4.4 Installation  Installation environment The VF-PS1 Inverter is an electronic control instrument. Take full consideration to installing it in the proper operating environment. Warning • Do not place any inflammable substances near the VF-PS1 Inverter. If an accident occurs in which flames are emitted, this could lead to fire. Prohibited •...
Page 35 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.
Page 36 Note2: Do not install in any location where there is high humidity or high temperatures and where there are large amounts of dust and metallic fragments. If you are going to install the equipment in any area that presents a potential problem, please consult with contact your Toshiba before doing so.  Current reduction curve Depending on the way in which the inverter is installed, the ambient temperature and the carrier frequency setting, you may need to reduce the inverter’s continuous output current.

Page 41 E6581386  Calorific values of the inverter and the required ventilation The energy loss when the inverter converts power from AC to DC and then back to AC is about 5%. In order to suppress the rise in temperature inside the cabinet when this loss becomes heat loss, the interior of the cabinet must be ventilated and cooled.
Page 42 E6581386  Panel designing taking into consideration the effects of noise The inverter generates high frequency noise. When designing the control panel setup, consideration must be given to that noise. Examples of measures are given below. • Wire so that the main circuit wires and the control circuit wires are separated. Do not place them in the same conduit, do not run them parallel, and do not bundle them.
Page 43: Connection Equipment
E6581386 2. Connection equipment Warning • Never disassemble, modify or repair. This can result in electric shock, fire and injury. For repairs, call your sales agency. Disassembly prohibited • Don't stick your fingers into openings such as cable wiring hole and cooling fan covers. This can result in electric shock or other injury.
Page 44 E6581386 Caution • Do not attach devices with built-in capacitors (such as noise filters or surge absorber) to the output (motor side) terminal. This could cause a fire. Prohibited  Preventing radio noise To prevent electrical interference such as radio noise, separately bundle wires to the main circuit's power terminals (R/L1, S/L2, T/L3) and wires to the motor terminals (U/T1, V/T2, W/T3).
Page 45: Standard Connections
E6581386 • Refer to the table in Section 10.1 for wire sizes. • The length of the main circuit wire in Section 10.1 should be no longer than 30m. If the wire is longer than 30m, the wire size (diameter) must be increased. •...

Page 56 E6581386  Sink logic/source logic (When inverter's internal power supply is used) Current flowing out turns control input terminals on. These are called sink logic terminals. The method generally used in Europe is source logic in which current flowing into the input terminal turns it on. Sink logic terminals and source logic terminals are sometimes referred to as negative logic terminals and positive logic terminals, respectively.
Page 57 E6581386  Sink logic/source logic (When an external power supply is used) The P24/PLC terminal is used to connect to an external power supply or to insulate a terminal from other input or output terminals. Use the slide switch SW1 to switch between sink logic and source logic configurations. Note that the PWR terminal is designed for safety purposes to work always in source logic mode, regardless of the setting of SW1.

So the conducted and radiated noise can be reduced, optional EMC noise filters are not needed.
Page 224 E6581386 (2) Use shielded power cables and control signal cables for the input and output lines of the inverter. Route the cables and wires so as to minimize their lengths. Keep a distance between the power cable and the control cable and between the input and output wires of the power cable.
