When installing the Inverter, always provide the following installation space to allow normal heat dis- sipation from 3g3ff Inverter. Chapter 2 Installation H Protecting Inverter from Foreign Matter During Installation Place a cover over the Inverter during installation to shield it from metal power produced by drilling.

Upon completion of installation, always remove the cover from the Inverter. Otherwise, ventilation will be affected, causing the Inverter to overheat. Not doing so may result 3h3fv electrical shock. Not doing so may result in electrical shock or fire. Remove the Digital Operator from the front cover before removing the front cover.

For models of 15 kW or less both V and V classdo not remove or mount the front cover 3g3ff first removing the Digital Operator; Chapter 2 Installation Mounting the Front Cover Mount the front cover to the Inverter by taking in reverse order to the steps to remove the front cover after wiring the terminals.

Do not mount the front cover with the Digital Operator attached to the front cover, otherwise Digital Operator may malfunction due to imperfect contact. Be sure to remove the short bar before connecting a DC reactor. The DC reactor is built in.

Models of to kW can not use the DC reactor. Chapter 2 Installation Wiring Around the Main Circuit System reliability and noise resistance are affected by the wiring method used.

There- fore, always follow the instructions given below when connecting the Inverter to periph- eral devices and other parts. Voltage class Model Terminal Install one wiring circuit breaker per Inverter.

Chapter 2 Installation Installing a Magnetic Contactor If the power supply of the main circuit is to be shut off because of the sequence, a magnetic contactor can be used instead of a molded-case circuit breaker. When a magnetic contactor is installed on the primary side of the main circuit to stop a load forcibly, however, the regenerative braking does not work and the load coasts to a stop.

It is recommended that a Noise Filter be installed at the Power Supply to minimize this noise transmission. Chapter 2 Installation Never Short or Ground Output Terminals If the output terminals are touched with bare hands or the output wires come into contact with the Invert- er casing, an electric shock or grounding will occur.


This is extremely hazardous. Also, be careful not to short the output wires. Chapter 2 Installation Countermeasures Against Induction Noise As described previously, a noise filter can be used to prevent induction noise from being generated on the output side.

Alternatively, cables can be routed through a grounded metal pipe to prevent induction noise. Chapter 2 Installation Note The carrier frequency setting range varies depending manhal the Inverter capacity. Chapter 2 Installation H Countermeasures against Harmonics With the continuing development of electronics, the generation of harmonics from industrial machines has been causing problems recently.

Refer to the following for the definition of harmonics i.


Harmonics Harmonic Currents with Voltages Definition Harmonics consist of electric power produced from AC power and alternating at frequencies that are The output current of the Inverter is comparatively high. Therefore, the ratio of harmonics in the output current of the Inverter is higher than that of any other electric machine. Chapter 2 Installation H Connecting the Braking Resistor Connect the braking resistor as shown in the following diagram.

Braking resistor Inverter Caution There are four types of PG speed control, as shown below. Select the type that fits the application and control method.

Chapter 2 Installation Solderless Terminals for Control Circuit Terminals The use of solderless terminals for the control circuit terminals is recommended because solderless terminals are easy to connect securely.

Wire thickness Model Manufacturer 0. Mqnual 2 Installation Note 6. Tighten the screws to a tightening torque of 0. The terminal block may be dam- aged if the tightening torque is too strong, and malfunctions and short-circuits may result if the tightening torque is too weak.

These function groups are known as modes. Chapter 3 Preparing for Operation Press the Mxnual Key to return to the mode display from the parameter display.

The access level restricts which parameters can be set or displayed. Chapter 3 Preparing for Operation The following diagram shows this procedure in flowchart format. There is no difference in other modes. This section provides the procedure to change the acceleration time to 20 s in each access level. The acceleration time C is a parameter in program mode.
