22cm or more for 18.5 to 75kW
30cm or more for 90 to 132kW

3. Operating Environment - Ambient Temperature

The ambient temperature surrounding the Inverter should not exceed the allowable temperature range
(-10 to 40ºC). When using at 50ºC of ambient air temperature, the rated output current will be reduced.
(P.4-18)
The temperature should be measured in the air gap surrounding the Inverter, shown in the diagram
above. If the temperature exceeds the allowable temperature, the component life will become shortened
especially in the case of the Capacitors.

4.Operating Environment - Humidity

The humidity surrounding the Inverter should be within the limit of the allowable percentage range (20%
to 90%). Under no circumstances should the Inverter be in an environment where there is the possibility of
moisture entering the Inverter.
Also avoid having the Inverter mounted in a place that is exposed to the direct sunlight.

 Chapter 2 Installation and Wiring

5. Operating Environment - Air

Install the Inverter avoiding any place that has dust, corrosive gas, explosive gas, combustible gas,
mist of coolant and sea damage.

6. Mounting Position
Mount the Inverter in a vertical position using screws or bolts. The surface you mount onto should also
be free from vibration and can easily hold the weight of the Inverter.

7. Ventilation within an Enclosure

If you are installing one or more Inverters in an enclosure a ventilation fan should be installed. Below is
a guide to the positioning of the fan to take the airflow into consideration. The positioning of Inverter,
cooling fans and air intake is very important. If these positions are wrong, airflow around the Inverter
decreases and the temperature surrounding the Inverter will rise. So please make sure that the
temperature around is within the limit of the allowable range.
Ventilation fan Ventilation fan

Inverter Inverter

(Good example) (Bad example)

8.External cooling of Inverter

It is possible to install the inverter so that the heatsink is out of the back of the enclosure. This method
has two advantages, cooling of the inverter is greatly increased and the size of the enclosure will be
smaller.
To install it with the heatsink out of the enclosure, a metal fitting option is required to ensure heat
transfer.
Do not install in a place where water, oil mist, flour and dust etc can come in contact with the inverter as
there are cooling fans fitted to the heatsink.

2.2.2 Main circuit wiring

(1) Warning on wiring
When carrying out work on the Inverter wiring make sure to wait for at least ten minutes before you
remove the cover. Making sure to check that the charge lamp is not illuminated. A final check should
always be made with a voltage meter. After removing the power supply, there is a time delay before the
capacitors will dissipate their charge.
1. Main power terminals(R, S, T)
• Connect the main power terminals (R, S, and T) to the power supply through a electromagnetic contactor
or an earth-leakage breaker.
• We recommend connecting the electromagnetic contactor to the main power terminals. Because when the
protective function of inverter operates, it isolates the powers supply and prevent the spread of damages
and accidents.
• This unit is for the three-phase power supply. It isn’t for the single-phase power supply. If you require a
single-phase power supply unit, please contact us.
• Don't operate with on/off of the switch set up in the converter side and the inverter side. Do an operation
stop by the operation order (FW/RV) terminals
• This inverter becomes the following condition at the time of open phase because open phase protection
is being made ineffective by the early data.
R phase or T phase, open phase condition: The power isn't turned on, and it doesn't operate.
S phase, open phase condition: It becomes single-phase operation condition. Trip operation such as a
deficiency voltage or over current may be done.
Don't use it under open phase condition.
• A converter module may be damaged in the case shown below. Be careful.
When an unbalance of the power supply voltage is more than 3%.
Power supply capacity, 10 times of the capacity of inverter and a case beyond 500kVA.
When a change in the rapid power supply voltage occur.
(Example) When inverter of the plural is installed with the common electric wire whose it is short by
each other.
When there is insertion of the condenser or a removal.
• On/off of the power supply isn't to do it more than three times in one minute. It has the possibility that
inverter is damaged.

2. Inverter output terminals (U, V, and W)

• Wire with thicker wire than the applicable wire to control the voltage drop. Particularly when outputting
low frequencies, the torque of the motor will reduce by the voltage drop of the wire.
• Do not install power factor correction capacitors or a surge absorber to the output. The inverter will trip or
sustain damage to the capacitors or the surge absorber.
• In the case of the cable length being more than 20 meters, it is possible that a surge voltage will be
generated and damage to the motor is caused by the floating capacity or the inductance in the wire (400V
especially). An EMC Mains Filter is available, please contact us.
• In the case of two or more motors, install a thermal relay to each motor.
• Make the RC value of the thermal relay the value of 1.1 times of motor rated electric current. Install output
ACL when a life becomes short by the length of wiring.

3. Direct current reactor (DCL) connection terminals (PD, P)

• These are the terminals to connect the current reactor DCL (Option) to help improve the power factor.
• The short bar is connected to the terminals when shipped from the factory, if you are to connect a DCL you

2-8
 Chapter 2 Installation and Wiring
will need to disconnect the short bar first.
• When you don’t use a DCL, don’t disconnect the short bar.

4. External braking resistor connection terminals (P, RB)

• The regenerative braking circuit (BRD) is built-in as standard up to the 15kW Inverter. When braking is
required, install an external-braking resistor to these terminals.
• The cable length should be less than 5 meters, and twist the two connecting wires to reduce inductance.
• Don’t connect any other device other than the external braking resistor to these terminals.
• When installing an external braking resistor make sure that the resistance is correctly rated to limit the
current drawn through the BRD.

5. Regenerative breaking unit connection terminals (P, N)

• The Inverters rated more than 18.5kW don’t contain a BRD circuit. If regenerative braking is required an
external BRD circuit (Option) is required along with the resistor (Option).
• Connect external regenerative braking unit terminals (P, N) to terminals (P,N) on the inverter. The braking
resistor is then wired into the External Braking unit and not directly to the Inverter.
• The cable length should be less than 5 meters, and twist the two connecting wires to reduce inductance.

6. Earth (G )
• Make sure that you securely ground the Inverter and motor for prevention of electric shock.
• The inverter and motor must be connected to an appropriate safety earth and follow the local standard.
Failure to do so constitutes an electrical shock hazard.

WARNING

Use suitable circuit breaker or fuse listed in this manual for UL’s listing purpose.
Otherwise, there is a danger of fire.

5) Connecting power to the control circuit, separating from main power

When the protection circuit of inverter is activated and the electromagnetic contactor on the input supply
to the inverter isolates the power supply, the control circuit power supply from the inverter will also switch off
and the alarm output signal will not be hold. The power terminals R0 and T0 are designed to allow a supply to
go direct to the control circuit and therefore keep the alarm output signal on. In this case, please connect
power terminals R0 and T0, to the primary side of the electromagnetic contactor. ( inverter unit side of ACL,
EMI filter, on using input ACL, EMI filter).
(Connection) [1] Remove the wires connected.

(1) Wiring
1. Both the CM1 and L terminal is insulated to both the common terminal of the input and output
signals. Do not short or earth these common terminals.
2. Use twisted screened cable, for the input and output wires of the control circuit terminals. Connect
the screen to the common terminal.
3. Limit connection wires to 20m. When it is necessary to wire over 20m, use a VX applied controller
RCD-A (Remoter operation bar) or a CVD-E (Insulated signal transducer).
4. Separate the control circuit wiring from the main power and relay control wiring.
5. If control and power wires must cross make sure they cross at 90 degrees to each other.
6. When connecting a thermistor to the TH and CM1 terminal, twist the thermistor cables separate
from the rests.

 Chapter 3 Operation

3.1 Operation
This inverter requires two different signals in order for the Inverter to operate correctly. The Inverter requires
both an operation setting and a frequency setting.
The following indicates the details of each method of operation and the necessary instructions for operation.
(1) Operation setting and a frequency setting by the terminal control.
This is the method by connecting signals from the outside (the frequency setting, the starting switch etc.)
with the control circuit terminals.
The operation is started when the operation setting (FW, RV) is turned ON while the input power is turned
ON.
(Note) The methods of the setting frequency with terminal are the voltage setting and the electric setting.
And they are selective by each system. The control circuit terminal list shows this in detail.

(Necessary things for operation)

[1] The operation setting: switch, relay etc.
[2] The frequency setting: signals from volume or external (DC0-10V, DC-10-10V, 4-20mA etc.)

Terminal

Operation Setting (switch)

Frequency setting (volume)

(2) Operation setting and frequency setting with the digital operator.
This is the method for operation from the digital operator, which comes equipped with the inverter as
standard, or the remote operator (SRW) keypad.
When the digital operator sets the operation, the terminals (FW, RV) don’t need to be linked.
And it is possible to select frequency from the digital operator as a method of the frequency setting too.
(Necessary things for operation)
[1] Remote Operator (SRW) (It’s unnecessary in case of digital operator operation)

Power Lamp
Volume
Digital Operator

(3) Operation setting and frequency setting from both digital operator and terminal operator
This is the method of inverter operating from both of the above two operating methods
It is possible that the operation setting and the frequency setting can be selected for both the digital
operator and the terminal operator each separately.

When the inverter starts, and the DB terminal is not ON the inverter can operate dc braking.
When using inside DC braking, the DC braking selection A051 should be set 01.
Starting DC braking power is set with A057, DC braking time at starting is set with A058.
Braking power setting except starting time, set with A054.
If DC braking late time A053 is set and the dc braking frequency is reached, the operating command (FW) is
switched OFF. The inverter cuts the output and for the set time of A053, free running of the motor will occur.
After finishing the set time in A053, DC braking is started.
Set the frequency at which the DC braking will operate at with A052.
The operation of Edge/Level selection when using inside DC braking is different.

braking is run.(Example 5-a),(Example 6-a)

Commercial power source switching(CS) b003 : retry waiting time
This function is used for systems with an excessive amount of starting b007 : frequency setting to
torque requirements. The motor would be started direct-on-line and then match
when the motor had started the inverter would take over. This function C001-C005 : Intelligent input terminal
is comonly used to reduce the costing of the inverter. For example, a system may
require 55kW to start but only 15kW to run at constant speed. Therefore, a 15kW rated inverter would be
sufficient when using the commerical power source switching. Assign 14(CS) to an intelligent input terminal.
Using the example below. When the motor has been started direct-on-line, Mg2 is switched OFF and Mg3 is
switched on. With the Forward command to the inverter already on the CS terminal is switched on and Mg1 is
closed. The Inverter will then read the motor RPM and when the CS terminal is switched OFF the retry wait
time (b003) is started.
Once the wait time has elapsed the inverter will then start and match the frequency which is set (b007).
When the Earth Leakage Breaker (ELB) trips on ground fault, the commercial circuit will not operate. When a
backup is required, take the supply from the commercial circuit ELBC.
For FWY, RVY, CSY, use control relays. The sequence above is reference to the circuit and timing diagram
below.
If an over-current trip occurs when frequency matching, extend the retry wait time (b003).
When the power is supplied to the inverter, also it is possible to activate retry operation too. In this case,
follwing CS terminal is out of necessary. For more information, refer to Reset(RS).

Stabilized factor Relation code

When the motor is hunting or unstable, this function can be adjusted to H006/H206: 1 st /2 nd stabilized factor
help stabilize the motor.
When the motor is unstable, check the allowable motor selection (H003/H203) and motor pole selection
(H004/H204) with your motor. If their code data is different from your motor specification, set the right data.
When R1 of usage motor is less than R1 of regular motor, raise the set value of H006/H206 gradually.
When you operate greater motor than rated capacity of inverter, lower the set value of H006/H206.
The following two functions can also assist to reduce hunting or rattling of a motor.
(1) Lower the carrier frequency (b083).
(2) Lower the output voltage gain (A045).

 Chapter 5 Maintenance, Inspection

5.5 The method to check Inverter, converter part

A test is possible to check quality.
(Preparation)
[1] Take out the power lines (R, S and T) connected to the inverter, the motor connection lines (U, V and
W) and the regenerative control resistance (P and RB).
[2] Prepare tester. (Using range of 1 ohm resistance measure range.)
(How to check)
It is possible to check the quality of the charging state of the terminals R, S, T, U, V, W, RB, P and N of
the inverter and the pole of the tester by measuring the charging state.
(Note 1) Before you measure the voltage between P and N with DC current range, confirm that the
smoothing capacitor is discharged fully, execute checks.
(Note 2) Almost infinite value is indicated on no conducting.
With the effect of the smoothing capacitor, the inverter conducts instantly and an infinite value isn’t
indicated. Ohm-number 10 ohms is indicated on conducting.
The values indicated will not be exactly the same for each terminal, however they will be very close
together. If there is a significant difference a problem may exist.
