Page 24: Notes On The Application
E6581595 Notes on the application 1.4.1 Motors When the VF-nC3 and the motor are used in conjunction, pay attention to the following items. 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 25 E6581595 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 26 E6581595 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 27 E6581595 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 28 E6581595  Disposal Refer to chapter 16. 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 29 E6581595 Remedies: 1. If there is no radio-frequency interference or similar problem, detach the built-in noise filter capacitor, using the grounding capacitor disconnecting switch. (Refer to section 1.3.3-2)) 2. Reduce : PWM carrier frequency. However the motor magnetic noise is increased. (Refer to section 6.11) 3.
Page 30 E6581595 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 more than 50 meters long, it will be easy for the high frequency component to pass through the externally connected CT and be superimposed on and burn the ammeter with models having motors of low rated current (several A (ampere) or less), because the leakage current will increase in proportion to the motor's rated current.

Page 198: Measures To Satisfy The Standards
E6581595 9. Measures to satisfy the standards 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.
