Connecting power to another terminal will damage the inverter. Check that the power voltage is
within the maximum allowable voltage marked on the nameplate, etc.
②Always ground the ground terminal to prevent disasters such as fire or electric shock and to
minimize noise.
③Use a reliable crimp terminal for connection between a terminal and a cable.
④After terminating the connection(wiring), confirm the following:
a. Confirm that the connection is correct.
b. Confirm that all necessary connections have been made.
c. Confirm that there is no short-circuit or ground fault between terminals and cables.
⑤Connection modification after power-on
The smoothing capacitor in the direct current portion of the main circuit cannot be discharged
immediately after the power is turned off. To ensure safety, use a multimeter to check that the
voltage of the direct current (DC) is lowered to the safety range (25V DC or less)after the charge
lamp goes off. Also, confirm that the voltage is zero before short-circuiting. The residual voltage
(electric charge) may causesparks.
• Always connect a ground wire.
Electric shock or fire may result.
!

inverter. The main circuit power should be used to start or stop the inverter only if absolutely necessary
and then should not be used more than once every hour.
④ If you need to connect these terminals to a single-phase power supply, please contact the factory.
(2) Inverter output terminals (U, V, W)
① Connect these terminals to a 3-phase motor in the correct phase sequence. If the direction of motor
rotation is incorrect, exchange any two of the U, V, and W phases.
② Do not connect a power factor correction capacitor or surge absorber to the inverter output.
③ If the cable from the inverter to the motor is very long, a high-frequency current may be generated by stray
capacitance between the cables and result in an overcurrent trip of the inverter, an increase in leakage
current, or a reduction in current indication precision.
When a motor is driven by a PWM-type drive, the motor terminals may be subject to surge voltage generated
by drive element switching. If the motor cable (with 460V series motors, in particular) is particularly long,
surge voltage will deteriorate motor insulation. To prevent this, use the following guidelines:
Inverters 7.5 HP and larger
Motor Insulation Level 1000V 1300V 1600V
460 VAC Input Voltage 66 ft (20 m) 328 ft (100 m) 1312 ft (400 m) *
230 VAC Input Voltage 1312 ft (400 m) * 1312 ft (400 m) * 1312 ft (400 m) *
Inverters 5 HP and smaller
Motor Insulation Level 1000V 1300V 1600V
460 VAC Input Voltage 66 ft (20 m) 165 ft (50 m) * 165 ft (50 m) *
230 VAC Input Voltage 328 ft (100 m) * 328 ft (100 m) * 328 ft (100 m) *
* For this case the cable length is determined by secondary effects and not voltage spiking.
Note: When a motor protective thermal O/L relay is inserted between the inverter and the motor, the thermal
O/L relay may malfunction (particularly in the 460V series), even when the cable length is 165 feet (50m) or
less. To correct, insert a filter or reduce the carrier frequency. (Use function code “F26 Motor sound”.)

(3) Auxiliary control-power input terminals (R0 and T0)
The inverter operates even if power is not
provided to these terminals.
If a protective circuit operates and the
magnetic contactor on the inverter power
side is opened (off), the inverter control circuit

the keypad panel display goes off. To prevent
this, the same AC power as the main circuit
AC power must be supplied (as auxiliary

① To ensure effective noise reduction when

using a radio noise filter, the output power
from the filter must go to the auxiliary
control-power input terminals.
If these terminals are connected to the input side of the filter, the noise reduction effect deteriorates.
Fig. 2-3-5 Connecting the auxiliary control-power input terminals
② When the RCD (Residual-current Protective Device) is installed (G11S:30HP or less), the terminal R0 and
T0 should be connected to the OUTPUT side of the RCD. If they are connected to the input side of the
RCD, RCD will be malfunction because the power supply of the inverter is three p hase and the terminal R0
and T0 is single phase.
When the terminal R0 and T0 are connected to the INPUT side of the
RCD, the insulation transformer is required to install as shown on the
Fig. 2-3-5.
(4) DC reactor connecting terminals (P1 and P (+))
① Before connecting a power-factor correcting DC reactor (optional) to
these terminals, remove the factory-installed jumper.
② If a DC reactor is not used, do not remove the jumper.
Note:For inverter of 100HP or more, the DC reactor is provided as a separate
standard component and should always be connected to the terminals.
Fig. 2-3-6
(5) External braking-resistor connecting terminals (P (+) and DB) (G11S:10HP or less)
For the G11S of 10HP or less, a built-in braking resistor is connected to terminals P (+) and DB.
If this braking resistor does not provide sufficient thermal capacity (e.g., in highly repetitive operation or heavy
inertia load operation), an external braking resistor (option) must be mounted to improve braking performance.
① Remove the built-in braking resistor from terminals P(+)
and DB. Insulate the resistor-removed terminals with
adhesive insulation tape, etc.
② Connect terminals P(+) and DB of the external braking
resistor to terminals P(+) and DB of the inverter.
③ The wiring (cables twisted or otherwise) should no t
exceed 16ft (5m).
(6) DC link circuit terminals (P (+) and N (-))
The G11S inverter of 15HP or more does not contain a
drive circuit for the braking resistor. To improve braking
performance, an external braking unit (option) and an external braking resistor (option) must be installe d.
① Connect terminals P(+) and N(-) of the braking unit
to terminals P(+) and N(-) of the inverter. The
wiring (cables twisted or otherwise) should not
exceed 16ft(5m).
② Connect terminals P(+) and DB of the braking
resistor to terminals P(+) and DB of the braking unit.
The wiring (cables twisted or otherwise) should not
exceed 33ft (10m). When terminals P (+) and N (-)
of the inverter are not used, leave terminals open.
If P (+) is connected to N (-) or the braking resistor
is connected directly, the resistor will break.
③ Auxiliary contacts 1 and 2 of the braking unit have
polarity. To connect the power regeneration unit, refer
to the "Power Regeneration Unit In struct ion Manu al".

(7) Inverter ground terminal
To ensure safety and noise reduction, always ground the inverter ground terminal. Also, metal frames of
electrical equipment must be grounded as specified in the Electric Facility Technical Standard.
The connection procedure is as follows:
① Ground metal frames to a ground terminal (Ground resistance:10Ω or less).
② Use a suitable cable (short and thick) to connect the inverter system to the ground terminal.
(8) Auxiliary power switching connector (CN UX) (for inverter of 40HP or more)
When an inverter of 40HP or more requires a main circuit power voltage as listed in Table 2-3-2, disconnect
auxiliary power switching connector CN UX from U1 and connect to U2. For the switching method, see Fig.
2-3-11.

(9) Fan power switching connector (CN RXTX) (for inverter of 40HP or more)
G11S without options supports DC power input via DC common connection by co nnecting the power
regeneration converter (RHC series) as shown in Fig. 2-3-10.
For details, refer to technical documentation.
The inverter of 40HP or more contains an AC-powered component (e.g., AC cooling fan).
To use the inverter using DC power input, switch the fan power switching connector (CN RTXT) inside the
inverter to the R0-T0 side and provide AC power to the R0 and T0 terminals. (See Fig. 2-3-9.)
For the switching method, see Fig. 2-3-11.
Note:
In the standard state, the fan power switching connector (CN RXTX) is connected to the L1/R-L3/T side.
When DC power input is not used, do not switch this connector.
The same AC voltage as the main circuit power voltage must be supplied to the auxiliary control- power input terminals
(R0 and T0). If not supplied, the fan does not rotate and the inverter will overheat (0H1).

To connect the power regeneration converter to an inverter of 30HP or less, do not connect the power supply directly to the auxiliary control-power input
terminals (R0 and T0) of the inverter. However, if such a connection is required, insulate these input terminals from the main power of the power
regeneration converter with an insulation transformer. The connection example of a power regeneration unit is provided in the "Power Regeneration
Unit Instruction Manual".

(1)Analog input terminals (13,12,V2,C1,and 11)
①These terminals receive weak analog signals that may be
affected by external noise. The cables must be as short as
possible (66ft (20m) or less), must be shielded, and must
be grounded in principle. If the cables are affected by
external induction noise, the shielding effect may be
improved by connecting the shield to terminal [11].
② If contacts must be connected to these circuits, twin
(bifurcated type) contacts for handling weak signals must
be used. A contact must not be connected to terminal
[11].
③If an external analog signal output device is connected to
these terminals, it may malfunction as a result of inverter
noise. To prevent malfunction, connect a ferrite core or
capacitor to the external analog signal output device.

(2) Digital input terminals (FWD, REV, X1 to X9 and CM)
① Digital input terminals (e.g., FWD, REV, X1 to X9)
are generally turned on or off by connecting or
disconnecting the line to or from the CM terminal. If
Digital input terminals are turned on or off by
switching the open collector output of PLC using an
external power supply, a resulting bypass circuit may
cause the inverter to malfunction.
To prevent a malfunction, connect the PLC terminal
as shown in Fig. 2-3-14.
② When using a contact input, a relay having highly
reliable contact must be used.

① To connect a control relay, connect a surge absorbing diode to both ends of its exciting coil.
(4) Others
① To prevent a malfunction as a result of noise, control terminal cables must be placed as far as possible
from the main circuit cables.
② The control cables inside the inverter must be secured to prevent direct contact with live section (e.g.,
main-circuit terminal block) of the main circuit.
Control lines generally do not have enhanced insulation. If the insulation of a
control line is damaged, the control signals may be exposed to high voltage in the

main circuit. The Low Voltage Directive in Europe also restricts the exposure to
high voltage.
Electric shock may result
The inverter, motor, and cables generate noise.
!
CAUTION
Check that the ambient sensors and devices do not malfunction.
Accident may result.
(5) Wiring of control circuit (inverter of 40HP or more)
① Pull out the control circuit wiring along the left panel as shown in Fig. 2-3-15.
② Secure the cable to cable binding hole A (on the left wall of the main circuit terminal block) using a cable-tie
(e.g., insulock). The cable-tie must not exceed 0.14inch (3.5mm) in width and 0.06inch (1.5mm ) in
thickness.
③ When the optional PC board is mounted, the signal lines must be secured to cable binding hole B.
