Chapter 2 Installation and Wiring
2-1 Installation Environment
Observe the following points when installing the inverter.
1) Install the inverter vertically so that the wire lead-in holes face
downward.
2) Make sure that the ambient temperature is -10ºC to 50ºC.
3) Avoid installation in the following environment.
• Places subject to direct sunlight
• Places with oil mist, dust or cotton lint, or subject to salty winds

• Places near vibration sources
• Places made of flammable materials such as wood, or places
that are not heat resistant
4) Ensure ventilation space around the inverter. (Refer to Fig.)
2-2 Installation
The upper installation holes are for hooks, and those on the lower side are notched. The VAT3FD
mass is approx. from 30 to 300kg, so installation by two workers with appropriate tools is
recommended.

CAUTION
Risk of electric shocks
An electrolytic capacitor is built into the VAT3FD, so there will be a charge even when the inverter power
is turned OFF. Observe the following items when wiring.
• Wait 20 minutes or more before starting work after turning the power OFF. Confirm that all indicators
on the operation are out before opening the cover.
• After opening the cover, confirm that the CHARGE lamp at the positions shown below is out. Check
the DC voltage between (P2) and (L-) and start the wiring only if the voltage measured is 15V or less.

Inverter Input/Output terminals
The inverter input terminals are L1, L2 and L3. The output terminals to the motor are U, V and
W. Do not connect the power supply to the U, V, W terminals. incorrect wiring will lead to
inverter damage.
Wire size
Use wires having the wire size or larger shown in Table 2.1 for the main circuit wiring shown in
Fig. 2.3. The applicable wire size range, applicable crimp terminal and tightening torque for
the main circuit terminal block are shown in Table 2.1.
Breaker for wiring
Install an MCCB on the power supply side of the inverter. Refer to Table 7.2 and select the
MCCB
Rated voltage for auxiliary equipment supply
For the 400 Series, replace the short bar for the auxiliary equipment power supply terminal
(TBA) according to the rated voltage of the power supply being used.
For 380 to 400V, short circuit across 2-3 (factory setting state)
For 415 to 460V, short circuit across 1-2
Power supply capacity
The capacity of the transformer used as the inverter power supply must be between 1.3 and
10 times the inverter capacity. (When using 4% impedance transformer.)
If the power supply transformer has a capacity that exceeds 10 times that of the inverter,
insert an ACL on the input side of the inverter. Refer to Table 7.2 and select the ACL. The
ACL is also effective for suppressing the high harmonic current and improving the power
factor.
Noise measures
The inverter will generate high harmonic electromagnetic noise, so using the following noise
measures is recommended.
When using the unit in the EU regions, the EMC Directives (89/336/EEC) must be followed.
Refer to this manual (section 7-3), and the separate “EMC Manual” when wiring.

2. Installation and Wiring
Note 7)
Note 8)
Note 9)
Note 10)
Note 11)
Note 12)
Note 13)
a) Insert a noise filter on the input side of the inverter. Refer to section 7.3 and select the
noise filter.
b) Keep the wiring length between the noise filter and inverter to 50cm or less.
c) Use a screen cable for the inverter and motor wiring, and connect the screen to the
inverter’s G terminal and motor grounding terminal.
d) When using the circuit control wiring explained in section 2-4 and the main circuit wiring in
this section in parallel, separate the wiring by 30cm or more, or pass each of the wiring
through metal conduits. If the control circuit wiring intersect, make sure that they intersect
at a right angle.
Inverter output
a) Do not insert a power factor improvement capacitor on the output side of the inverter.
b) When inserting a magnetic contactor on the output side of the inverter, prepare a
sequence control circuit so that the magnetic contactor will open and close when the
inverter stops.
Grounding
Always ground the inverter unit grounding terminal (G) and the ground according to the
regulations of the Country where the inverter is being used . Ground the motor grounding at
the motor installation position.
Inverter output surge voltage (For 400V Series)
As the inverter output cable is lengthened, the surge voltage applied on the motor also
increases. If the wiring between the inverter and motor exceeds 20m, connect a surge
absorber exclusive for the inverter output.
DCL
Always short circuit across P1 and P2 when not using DCL. (Factory setting state)
When connecting the optional DCL, connect it to P1 and P2.
Twist the wiring to the DCL, and keep the wiring length to 5m or less.
DBR unit
When connecting the optional DBR unit, follow Fig. 2.3 and connect the P2 and L-. The DBR
unit and inverter unit will both be damaged if the connection is mistaken.
Twist the wiring to the DBR unit, and keep the wiring length to 3m or less.
Refer to section 7-2 for details.
DRB protection
When using the optional DBR unit, insert a thermal relay (76D) to protect the DBR resistor
and inverter. Prepare a sequence control circuit to turn OFF the magnetic contactor (MC) on
the input side of the inverter or trip the wiring breaker (MCCB) with trip coil using this relay
contact.
Installation of surge absorber
Install a surge absorber on the magnetic contactor and relay coils installed near the inverter.

FWD
(Forward)
The drive is running in the forward
direction.
REV
(Reverse)
The drive is running in the reverse
direction.
FLT
(Fault)
The drive has detected a fault and has stalled. The drive can be reset from the
Operation Panel (STOP + RST/MOD) or from the terminal block (external RESET)
LCL
(Local)
The drive is in the Local Mode and can be operated from the Operation Panel
(FWD. REV and STOP only). When lamp is off, the drive is in the Remote Mode
and can be controlled from the terminal block (external sequence commands). To
change Modes, press STOP + LCL/SET.
When both lamps flicker simultaneously, it
indicates that DC Brake is in action.
When either of the lamps flickers, it
indicates that the drive is ramping down
against a command to change directions.
Unit Indication LEDs
Hz-A-%
Indicate the unit of the value shown on the display.
rpm
Indicate that the value shown on the display is the multiple of a parameter set on
