H Installation Precautions
WARNING Provide an appropriate stopping device on the machine side to secure safety. (A
holding brake is not a stopping device for securing safety.) Not doing so may result in injury.
WARNING Provide an external emergency stopping device that allows an instantaneous stop of
operation and power interruption. Not doing so may result in injury.
Caution Be sure to install the product in the correct direction and provide specified clear-
ances between the Inverter and control panel or with other devices. Not doing so may result in fire or malfunction.
Caution Do not allow foreign objects to enter inside the product. Doing so may result in fire or
malfunction.
Caution Do not apply any strong impact. Doing so may result in damage to the product or
malfunction.
H Direction and Dimensions
Install the Inverter on a vertical surface so that the characters on the nameplate are oriented upward.
When installing the Inverter, always provide the following installation space to allow normal heat dis-
sipation from the Inverter.

H Installation Site
Install the Inverter under the following conditions.
NEMA1 Type
Ambient temperature for operation: –10°C to 40°C Humidity: 90% RH or less (no condensation)
Open Chassis Type
Ambient temperature for operation: –10°C to 45°C Humidity: 90% RH or less (no condensation)
Note Remove the top and bottom covers when using the open chassis type of 15 kW or less.
Install the Inverter in a clean location free from oil mist and dust. Alternatively, install it in a totally en-
closed panel that is completely shielded from floating dust.
When installing or operating the Inverter, always take special care so that metal powder, oil, water, or
other foreign matter does not get into the Inverter.
Do not install the Inverter on inflammable material such as wood.
H Ambient Temperature Control
To enhance operation reliability, the Inverter should be installed in an environment free from extreme
temperature rises.
If the Inverter is installed in an enclosed environment such as a box, use a cooling fan or air conditioner
to maintain the internal air temperature below 45°C.
H Protecting Inverter from Foreign Matter During Installation
Place a cover over the Inverter during installation to shield it from metal powder produced by drilling.
Upon completion of installation, always remove the cover from the Inverter. Otherwise, ventilation will
be affected, causing the Inverter to overheat.

class, or 1 0 or less for the 400-V AC class. Not connecting to a proper ground may result in electrical shock.
Caution Install external breakers and take other safety measures against short-circuiting in
external wiring. Not doing so may result in fire.
Caution Confirm that the rated input voltage of the Inverter is the same as the AC power sup-
ply voltage. An incorrect power supply may result in fire, injury, or malfunction.
Caution Connect the Braking Resistor and Braking Resistor Unit as specified in the manual.
Not doing so may result in fire.
Caution Be sure to wire correctly and securely. Not doing so may result in injury or damage to
the product.
Caution Be sure to firmly tighten the screws on the terminal block. Not doing so may result in
fire, injury, or damage to the product.

H Conformance to EMC Directives
In order to conform to EMC Directives, the exclusive-use methods are required for noise filter applica­tion, cable shielding, and Inverter installation. The following provides an outline of the methods.
The noise filter and the Inverter must be mounted on the same metal plate. The filter should be mounted as close to the Inverter as practical. Keep the cable as short as possible (40 cm max.). The metal plate should be securely grounded. The ground of the noise filter and Inverter must be bonded to the metal plate using as large an area as possible (after peeling off the paint on the Inverter and the metal plate).
For the mains input cable, screened cable is recommended at least within the control panel. The screen of the cable should be connected to a solid ground. For the motor cable, screened cable (20 m max.) must be used and the screen of the motor cable is connected to the ground at both ends by a short connection, using as large an area as possible.
Ground to the supply neutral, which will increase the effect of the noise filter. The following table and figures provide the noise filter list for the EMC Directives and the installation and
wiring of the Inverter and noise filter.

H Wiring on the Input Side of Main Circuit
D Installing a Molded-case Circuit Breaker
Provide fuses recommended for each Inverter between the power supply and the power input terminals (L1, L2, and L3). It is recommended that a molded case circuit breaker (MCCB) that matches the Invert­er be provided between the power supply and the input terminals to facilitate easy operation and main­tenance.
Install one MCCB for each Unit.
Choose an MCCB with a capacity of 1.5 to 2 times the Inverters rated current.
For the MCCBs time characteristics, be sure to consider the Inverters overload protection (one min-
ute at 150% of the rated output current).
Since diodes and cables of individual Inverters need not be protected, if the MCCB is to be used in common among multiple Inverters or other devices, set up a sequence such that the power supply will be turned off by an fault output, as shown in the following diagram.

Note 1. Terminals 19 and 20 are terminal numbers for the 3G3FV, and MB and MC are terminal num-
bers for the 3G3FV. Since the terminals MB and MC are multi-functional outputs, set to “Error (n040=0).
Note 2. Connect a 400-/200-V transformer for the 2,400-V-class model.
D Installing a Ground Fault Interrupter
Inverter outputs use high-speed switching, so high-frequency leakage current is generated. In general, a leakage current of approximately 100 mA will occur for each Inverter (when the power cable is 1 m), and approximately 5 mA for each additional meter of power cable. Therefore, at the power supply input area, use a special-purpose breaker for Inverters, which detects only the leakage current in the frequen­cy range that is hazardous to humans and excludes high-frequency leakage current.
Countermeasures taken for the EMC tend to increase the leakage current, therefore careful attention must be paid in selecting a breaker.
For the special-purpose breaker for Inverters, choose a ground fault interrupter with a sensitivity am­perage of at least10 mA per Inverter.
When using a general leakage breaker, choose a ground fault interrupter with a sensitivity amperage of 200 mA or more per Inverter and with an operating time of 0.1 s or more.

2-33
D Installing a Magnetic Contactor
If the power supply for 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 forcibly stop a load, however, the regenerative braking does not work and the load coasts to a stop.
The load can be run or stopped by switching the magnetic contactor in the primary side. Frequent switching of the contactor, however, may result in Inverter troubles. It is recommended that switching be limited to once half an hour, considering the life of electrolytic capacitors or relay contacts inside the Inverter.
When the Inverter is operated with the Digital Operator, automatic operation cannot be performed af­ter recovery from a power interruption.
If the Braking Resistor Unit is to be used, program the sequence so that the magnetic contactor is turned off by the contact of the Unit’s thermal relay.
D Connecting Input Power Supply to the Terminal Block
Input power supply can be connected to any terminal on the terminal block because the phase se­quence of input power supply is irrelevant to the phase sequence (L1, L2, and L3).
D Installing an AC Reactor
If the Inverter is connected to a large-capacity power transformer (600 kW or more) or the phase ad­vance capacitor is switched, an excessive peak current may flow through the input power circuit, caus­ing the converter unit to break down. To prevent this, install an optional AC reactor on the input side of the Inverter. This also improves the power factor on the power supply side.
D Installing a Surge Absorber
Always use a surge absorber or diode for the inductive loads near the Inverter. These inductive loads include magnetic contactors, electromagnetic relays, solenoid valves, solenoids, and magnetic brakes.
D Wiring the Power Terminal of the Inverter with 18.5- to 160-kW Output
For 400-V class, 18.5 to 45 kW, connect the r and s terminals to the L1 (R) and L2 (S) terminals respec­tively. (These are shorted by short bars for shipping.)
For 400-V class, 55 to 160 kW, connect the r and s 400 terminals to the L1 (R) and L2 (S) terminals respectively. (These are shorted by short bars for shipping.)
D Wiring the Power Terminal of the Inverter with 3G3HV Series with 18.5- to 160-kW
Output
Refer to the following to wire terminals R, S, T, R1, S1, and T1.
D Three-phase Power Input
Make sure that terminals R and R1, S and S1, and T and T1 are short-circuited before supplying power to the Inverter. These terminals are short-circuited with short bars before shipping. The Inverter may break down if only terminals R, S, and T or terminals R1, S1, and T1 are supplied with power.
D 12-pulse Rectification
Terminals R and R1, S and S1, and T and T1 are short-circuited with short bars before shipping. Be sure to remove the short bars when using 12-pulse rectification, otherwise the Inverter will break down.

H Wiring on the Output Side of Main Circuit
D Connecting the Terminal Block to the Load
Connect output terminals T1 (U), T2 (V), and T3 (W) to motor lead wires T1 (U), T2 (V), and T3 (W), respectively . Check that the motor rotates forward with the forward command. Switch over any two of the output terminals to each other and reconnect if the motor rotates in reverse with the forward com­mand.
D Never Connect a Power Supply to Output Terminals
Never connect a power supply to output terminals T1 (U), T2 (V), and T3 (W). If voltage is applied to the output terminals, the internal circuit of the Inverter will be damaged.
D Never Short or Ground Output Terminals
If the output terminals are touched with bare hands or the output wires come into contact with the Invert­er casing, an electric shock or grounding will occur. This is extremely hazardous. Also, be careful not to short the output wires.
D Do Not Use a Phase Advancing Capacitor or Noise Filter
Never to connect a phase advance capacitor or LC/RC noise filter to the output circuit. Doing so may result in damage to the Inverter or cause other parts to burn.
D Do Not Use an Electromagnetic Switch or Magnetic Contactor
Do not connect an electromagnetic switch or magnetic contactor to the output circuit. If a load is con­nected to the Inverter during running, an inrush current will actuate the overcurrent protective circuit in the Inverter.
D Installing a Thermal Relay
This Inverter has an electronic thermal protection function to protect the motor from overheating. If, however, more than one motor is operated with one Inverter or multi-polar motor is used, always install a thermal relay (THR) between the Inverter and the motor and set n033 to 0 (no thermal protection). In this case, program the sequence so that the magnetic contactor on the input side of the main circuit is turned off by the contact of the thermal relay.
D Installing a Noise Filter on Output Side
Connect a noise filter to the output side of the Inverter to reduce radio noise and induction noise.

Induction Noise: Electromagnetic induction generates noise on the signal line, causing the controller
to malfunction.
Radio Noise: Electromagnetic waves from the Inverter and cables cause the broadcasting radio
receiver to make noise.
D Cable Length between Inverter and Motor
As the cable length between the Inverter and the motor is increased, the floating capacity between the Inverter outputs and the ground is increased proportionally. The increase in floating capacity at the In­verter outputs causes the high-frequency leakage current to increase, and this may adversely affect peripheral devices and the current detector in the Inverters output section. To prevent this from occur­ring, use a cable of no more than 100 meters between the Inverter and the motor. If the cable must be longer than 100 meters, take measures to reduce the floating capacity by not wiring in metallic ducts, by using a separate cable for each phase, and so on.
Also adjust the carrier frequency according to the cable length between the Inverter and the motor, as shown in the table below.

Cable length 20 m max. 40 m max. More than 40 m
Carrier frequency 15 kHz max. 10 kHz max. 5 kHz max.

3G3HV (Set value: n050) (6) (4) (2)
Note 1. If the cable length exceeds 20 m, final check must be made for the whole system to conform to
the EMC Directive.
Note 2. The upper limit of carrier frequency depends on the inverter capacities as shown below.
3G3FV: 15 kHz for 30 kW or smaller models, 10 kHz for 37 kW or larger models 3G3HV: 15 kHz for 22 kW or smaller models, 10 kHz for 30 kW or larger models
Note 3. If the inverter overload (OL2) is detected before motor overload (OL1), lower the carrier fre-
quency setting.
D Single-phase Motors Cannot Be Used
The Inverter is not suited for the variable speed control of single-phase motors. Single-phase motors are either capacitor start motors or split-phase start motors. (The method for de-
termining rotation direction at startup is different.) If a capacitor start motor is used, the capacitor may be damaged by a sudden electric discharge caused by Inverter output. If a split-phase start motor is used, the starting coil may burn because the centrifugal switch does not operate.

H Ground Wiring
Connect the ground terminal to the supply neutral (neutral point of the input power supply).
Always use the ground terminal of the 200-V Inverter with a ground resistance of less than 100 and that of the 400-V Inverter with a ground resistance of less than 10 Ω.
Do not share the ground wire with other devices such as welding machines or power tools.
Connect the ground terminal before connecting any other terminal. When removing the wiring, re-
move the ground wire last.
Always use a ground wire that complies with technical standards on electrical equipment and mini­mize the length of the ground wire. Leakage current flows through the Inverter. Therefore, if the distance between the ground electrode and the ground terminal is too long, potential on the ground terminal of the Inverter will become unsta­ble.
When using more than one Inverter, be careful not to loop the ground wire.

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.e., harmonic currents with voltages) and countermeasures against the generation of harmonics from the Inverter.
D Harmonics (Harmonic Currents with Voltages)
Definition
Harmonics consist of electric power produced from AC power and alternating at frequencies that are integral multiples of the frequency of the AC power. The following are the harmonic frequencies of a 60- or 50-Hz commercial power supply. Second harmonic: 120 (100) Hz Third harmonic: 180 (150) Hz
Basic frequency (60 Hz)
Second harmonic (120 Hz)
Third harmonic (180 Hz)
Problems Caused by Harmonics Generation
The waveform of the commercial power supply will be distorted if the commercial power supply con­tains excessive harmonics. Machines with such a commercial power supply will malfunction or generate excessive heat.
Third harmonic (180 Hz)Basic frequency (60 Hz)
Distorted current waveform
D Causes of Harmonics Generation
Usually, electric machines have built-in circuitry that converts commercial AC power supply into DC power. Such AC power, however, contains harmonics due to the dif ference in current flow between AC and DC.
Obtaining DC from AC using Rectifiers and Capacitors
DC voltage is obtained by converting AC voltage into a pulsating one-side voltage with rectifiers and smoothing the pulsating one-side voltage with capacitors. Such AC current, however, contains har­monics.

!
2-38
Inverter
The Inverter as well as normal electric machines has an input current containing harmonics because the Inverter converts AC into DC. 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.

A current flows into the capacitors. The current is different from the voltage in waveform.
D Countermeasures with Reactors against Harmonics Generation
DC/AC Reactors
The DC reactor and AC reactor suppress harmonics and currents that change suddenly and greatly. The DC reactor suppresses harmonics better than the AC reactor. The DC reactor used with the AC reactor suppresses harmonics more effectively. The input power factor of the Inverter is improved by suppressing the harmonics in the input current of the Inverter.
Note 18.5- to 160-kW models have a built-in DC reactor.
Connection
Connect the DC reactor to the internal DC power supply of the Inverter after shutting off the power supply to the Inverter and making sure that the charge indicator of the Inverter turns off.
WARNING Do not touch the internal circuitry of the Inverter in operation, otherwise an electric
shock or a burn injury may occur.

The 3G3HV-series Inverter with an output of 18.5 to 160 kW can employ 12-pulse rectification, which suppresses harmonics better than reactors. The 3G3HV-series Inverter with an output of 15 kW or less cannot employ 12-pulse rectification.
Wiring Method
1. Terminals L1 (R) and L11 (R1), L2 (S) and L21 (S1), and L3 (T) and L31 (T1) are short-circuited with short bars before shipping. Be sure to remove the short bars when employing 12-pulse rectification, otherwise the Inverter will break down.
2. Do not ground the secondary winding side of the transformer, otherwise the Inverter may break down.

H Connecting the Braking Resistor
Connect the braking resistor as shown in the following diagram.
When using a Braking Resistor for the 3G3FV, set L8-01 to 1 (i.e., overheating protection of the brak-
ing resistor) and set L3-04 to “0” (i.e., no decelerating stall prevention) or “2 (braking function with stall prevention).
For the 3G3HV, set n079 (braking resistor overheating protection) to “1 and n070 (no decelerating stall prevention) to “0.”
Inverter
Braking resistor
Caution The braking resistor’s connection terminals are B1 and B2. Do not connect any other
terminals. Connecting any terminals other than B1 or B2 can cause the resistor to overheat, resulting in damage to the equipment.

H Connecting the Braking Resistor Unit and Braking Unit
Connect the Braking Resistor Unit and Braking Unit to the Inverter as shown in the following diagrams.
For the 3G3FV, set L8-01 to 0 (i.e., no overheating protection of the braking resistor) and L3-04 to 0
(i.e., no decelerating stall prevention) or “2” (braking function with stall prevention) before using the Inverter with the Braking Resistor Unit connected.
For the 3G3HV, set n079 to “1 and n070 to “0.
Note 1. Set L8-01 to “1 (n079 to 1) when operating the Inverter with the braking resistor without
thermal relay trip contacts.
Note 2. The Braking Resistor Unit cannot be used and the deceleration time cannot be shortened by
the Inverter if L3-04 (n070) is set to “1” (i.e., decelerating stall prevention).
To prevent the Unit from overheating, make a power supply sequence as shown below or connect the thermal relay trip output of the Unit to the external fault input terminal of the Inverter to interrupt the running of the Inverter.

H Wiring Control Circuit Terminals
D Wiring Method
1. Loosen the terminal screws with a thin-slotted screwdriver.
2. Insert the wires from underneath the terminal block.
3. Tighten the terminal screws firmly.
Note 1. Always separate the control signal line from the main circuit cables and other power cables. Note 2. Do not solder the wires to the control circuit terminals. The wires may not contact well with the
control circuit terminals if the wires are soldered.
Note 3. The end of each wire connected to the control circuit terminals must be stripped for approxi-
mately 7 mm.
Note 4. Use a shielded wire for the ground terminal. Note 5. Insulate the shield with tape so that the shield will not touch any signal line or device. Note 6. Tighten screws to a torque of 0.5 to 0.6 NSm. Tightening screws to a torque exceeding this
value may damage terminal blocks. On the other hand, loosely tightened screws may cause malfunctions or short-circuits.
Strip the end for 7 mm if no solderless terminal is used.
