Caution Use an inverter that conforms to the specifications of power supply and three-phase induction motor being operated. If the inverter being used does not conform to those specifications, not only will the three-phase induction motor not rotate correctly, but it may cause serious accidents through overheating Mandatory and fire.
Page 27 E6582233 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 load percentage, or when the load's inertia moment is extremely small. If that happens reduce the carrier frequency.
Page 28 E6582233 Motors with a brake When motors with a brake are directly connected to the inverter's output, the brake cannot be released at startup because of low voltage. Wire the brake circuit separately from the main circuit. 3-phase FLB FLC S2 (ST) NO CC 3-phase power...
Page 29 E6582233 Power factor correction capacitor Power factor correction capacitors cannot be installed on the output side of the inverter. When a motor is run that has a power factor correction capacitor attached to it, remove the capacitors. This can cause inverter malfunction and capacitor destruction.
Page 30 E6582233  Disposal Refer to chapter 15. 1.4.3 What to do about the leakage current Caution Current may leak through the inverter's input/output wires because of insufficient electrostatic capacity on the motor with bad effects on peripheral equipment. The leakage current’s value is affected by the carrier frequency and the length of the input/output wires. Mandatory Test and adopt the following remedies against leak current.
Page 31 E6582233 Remedies: 1. Reduce PWM carrier frequency. The setting of PWM carrier frequency is done with the parameter  Although the electromagnetic noise level is reduced, the motor acoustic noise is increased. 2.

Page 32 E6582233 CT and ammeter If a CT and ammeter are connected externally to detect inverter output current, the leak current's high frequency component may destroy the ammeter. If the wires are ling (50 meters or more), or in case of models with motors of low rated current (several A (ampere) or less), the high frequency component of leakage current may pass through the externally connected CT and it may burn the ammeter connected CT, because the ratio of leakage current against the motor's rated current will increase.
Page 33 If the inverter is installed in a location that is subject to vibration, anti-vibration measures are required. Please consult with Toshiba about these measures.  If the inverter is installed near any of the equipment listed below, provide measures to insure against errors in operation.
Page 34 Warning  Do not install or operate the inverter if it is damaged or any component is missing. This can result in electric shock or fire. Contact your Toshiba distributor for repairs. Prohibited  Mount the inverter on a metal plate.
Page 35 E6582233 The space shown in the diagram is the minimum allowable space. Because air cooled equipment has cooling fans built in on the top or bottom surfaces, make the space on top and bottom as large as possible to allow for air passage.
Page 36 E6582233  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 37 2. Connection Warning  Never disassemble, modify or repair. This can result in electric shock, fire and injury. Call your Toshiba distributor for repairs. Disassembly prohibited  Don't stick your fingers into openings such as cable wiring hole and cooling fan covers.

Page 250 E6582233 16. Appendix ■ How to cope with the CE directive In Europe, the EMC directive and the low-voltage directive, which took effect in 1996 and 1997, respectively, made it obligatory to put the CE mark on every applicable product to prove that it complies with the directives. Inverters do not work alone but are designed to be installed in a control panel and always used in combination with other machines or systems which control them, so they themselves are not considered to be subject to the EMC directive.
Page 251 IEC61000-4-11 2. About the low-voltage directive The low-voltage directive provides for the safety of machines and systems. All Toshiba inverters are CE-marked in accordance with the standard EN 50178 specified by the low-voltage directive, and can therefore be installed in machines or systems and imported without problem to European countries.
