environment.
Failure to observe this could lead to faults.
Install an overheating protection device on the dynamic braking resistor, and shut off the power
with this fault signal.
Failure to do so could lead to fires in the event of abnormal overheating.
2-1 Installation environment
Observe the following points when installing the AC Drive.
(1) Install the AC Drive vertically to provide proper ventilation.
(2) Make sure that the ambient temperature is 0°C (32°F) to
50°C (122°F) for 400 Volt series Drive and 0°C (32°F) to 40°C
(104°F) for 500 Volt and 600 Volt series Drive.
(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 with corrosive gas, explosive gas or high humidity
levels.
•Places near vibration sources such as dollies or press
machines.
•Places made of in-flammable materials such as wood, or
places that are not heat resistant.
(4) Ensure ventilation space around the AC DRIVE as shown in
the below figure.

2-2 Precautions for power supply and motor wiring
DANGER
Always turn the device's input power OFF before starting wiring.
Failure to do so could lead to electric shocks or fires.
Carry out grounding that complies with the standards of the country where the AC DRIVE is being
installed.
Failure to do so could lead to electric shocks or fires.
Wiring must always be done by a qualified electrician
Failure to observe this could lead to electric shocks or fires.
Always install the device before starting wiring.
Failure to do so could lead to electric shocks or injuries.
Use circuit breaker or fuses that match with the capacity of AC DRIVE power supply.
Failure to do so could lead to fires.
CAUTION
Do not connect an AC power supply to the output terminals (U, V, W) and DC terminals (L+1,
L+2, and L–).
Failure to observe this could lead to injuries or fires.
Confirm that the product's rated input voltage and frequency match the power supply voltage and
frequency.
Failure to do so could lead to injuries or fires.
Install an overheating protection device on the dynamic braking resistor, and shut off the power
with this fault signal.
Failure to do so could lead to fires in the event of abnormal overheating.
Do not directly connect a resistor to the DC terminals (L+1, L+2, and L–).
Failure to observe this could lead to fires.
Tighten the terminal screws with the designated tightening torque.
Failure to do so could lead to fires.
Correctly connect the output (U, V, W) to motor terminals to ensure proper phase sequence.
Failure to do so could cause the motor to rotate in reverse and the machine to be damaged.
When using the encoder, ensure its proper connections. The signal polarity specifications differ
according to the encoder. If the specifications differ from the specified AC DRIVE standard
specifications, correct the signal polarity as specified. Refer Chapter-10 for more information on
encoder specifications.
Failure to observe this could lead to reverse rotation or abnormal acceleration of the motor, and to
injuries or machine damage.
Refer to below figure and wire the main circuits for the power supply and motor, etc.
Always observe the following precautions for wiring.
CAUTION
There is a risk of electric shocks.
The AC DRIVE has a built-in electrolytic capacitor, so a charge will remain even when the AC DRIVE
power is turned off. Always observe the following items before carrying out the wiring work.
Wait at least 20 minutes after turning the power off before starting work. Make sure that the
displays on the Digital Operation Panel have gone out before removing the cover.

After removing the cover, confirm that the “DC BUS CHARGE LED“ in the unit on bleeder board
has gone out. Also check that the voltage between terminals L+1 or L+2 and L- is 15V or less
before starting the inspections.

(Note 1) AC DRIVE input / output terminals
The AC DRIVE input terminals are L1, L2 & L3. The output terminals to the motor are U, V & W.
Connect the power supply to input terminals L1, L2 & L3 only. Never connect the power supply to
the U, V, and W terminals. Incorrect wiring will lead to AC DRIVE damage or fires.
(Note 2) Wire size
Use wires having the size (or larger) shown in the below table for the main circuit wiring shown in
the above figure. The applicable wire size range, applicable ring terminal and tightening torque for
the main circuit terminals are shown in the Table-1 for 400V Series, Table-2 for 500V Series and

(Note 3) Breaker for wiring
Install circuit breaker or fuse on the power supply side of the AC DRIVE. Refer to table and select
the Circuit Breaker or Fuses.
(Note 4) Power supply capacity
Make sure that the capacity of the transformer used as the AC DRIVE’s power supply is 10 times
(or less) AC DRIVE capacity (for 4% impedance transformer). If the above value is exceeded,
install an ACL on the AC DRIVE’s input side.
(Note 5) Noise filter
The AC DRIVE will generate high harmonic electromagnetic noise, so using the following noise
measures is recommended.
Insert a noise filter on the input side of the AC DRIVE. Contact Amtech to select the proper noise
filter.
Keep the wiring length between the noise filter and AC DRIVE to 500mm (19.7”) or less.

Use a shield cable for the AC DRIVE and motor wiring and connect the screen to the AC DRIVE’s
terminal.
When using the control circuit wiring and power circuit wiring in parallel, separate the wiring by
300mm (11.8”) or more or pass each of the wiring through separate metal conduits. If the control
circuit wiring and main circuit wiring intersect, make sure that they intersect at a right angle.
(Note 6) AC DRIVE output
Do not insert a power factor improvement capacitor on the output side of the AC DRIVE. When
inserting a magnetic contactor on the output side of the AC DRIVE, prepare a sequence control
circuit so that the magnetic contactor will not open and close when the AC DRIVE is running.
Directly connect only motor to the AC DRIVE load and do not connect through a transformer
etc...without consulting Amtech.
(Note 7) Grounding
Always ground the AC DRIVE unit according to the regulations of the country where the AC
DRIVE is being used to ensure personnel safety in all circumstances, and to reduce
electromagnetic emission and pickup.
Make sure that grounding conductors are adequately sized as required by safety regulations.
In a multiple-drive installation, connect each drive separately to protective earth.
In European CE compliant installations and in other installations where EMC emissions must be
minimized, make a 360° high frequency grounding of cable entries in order to suppress
electromagnetic disturbances.
In addition, connect the cable shields to protective earth (PE) in order to meet safety regulations.
As the normal leakage current of the drive is higher than 3.5 mA AC or 10 mA
DC (stated by EN 50178, 5.2.11.1), a fixed protective earth connection is required.
(Note 8) AC DRIVE output surge voltage
As the AC DRIVE output cable is lengthened, the surge voltage applied on the motor also
increases. If the wiring between the AC DRIVE and motor exceeds 20meters (65.6’), connect a
surge absorber dedicated for the AC DRIVE output.
(Note 9) DCL
Always short across L+1 and L+2 when not using the DCL (factory setting state). When
connecting the optional DCL, connect it to L+1 and L+2. Twist the wiring to the DCL, and keep the
wiring length to 5meters (16.4’) or less.
(Note 10) DB Unit
When connecting an optional DB unit, make the connections as shown in the main circuit wiring.
The DB unit and AC DRIVE unit will damage if the connections are incorrect. Twist the wiring to
the DB unit, and keep length to 3meters (9.8’) or less.
When using the external DB unit, use the overload detection relay or thermal relay to protect the
DB resistor and AC DRIVE.
(Note 11) Surge absorber
Install a surge absorber on the magnetic contactor and relay coils installed near the AC DRIVE.
(Note 12) Voltage Selection for the auxiliary equipment Power Supply
Ensure appropriate tapping for the control transformer, which provides the power supply to the
auxiliary equipments like fan/blower, soft charge contactor etc.
