WARNINGS FOR UL/cUL MARKING
•Do not connect or disconnect wiring, or perform signal checks while the
power supply is turned ON.
•The Inverter internal capacitor is still charged even after the power supply
is turnd OFF. To prevent electric shock, disconnect all power before
servicing the Inverter. Then wait at least one minute after the power
supply is disconnected and all indecators are OFF.
•Do not perform a withstand voltage test on any part of the Inverter. This
electronic equipment uses semiconductors and is vulnerable to high
voltage.
•Do not remove the Digital Operator or the blank cover unless the power
supply is turned OFF. Never touch the printed control board (PCB) while
the power supply is turned ON.
•This Inverter is not suitable for use on a circuit capable of delivering more
than 18,000 RMS symmetrical amperes, 250volts maximum (200V class
units) or 18,000 RMS symmetrical amperes, 480volts maximum (400V
class units).
WARNINGS FOR CE MARKINGS
•Only basic insulation to meet the requirements of protection class 1 and
overvoltage category II is provided with control circuit terminals.
Additional insulation may be necessary in the end product to conform to
CE requirements.
•For 400 V class Inverters, make sure to ground the supply neutral to
conform to CE requirements.
•For conformance to EMC directives, refer to the relevant manuals for the
requirements.
Document No. EZZ008389 for Japanese version,
Document No. EZZ008390 for English version
CAUTION
Use 75°C copper wires or equivalent.
Low voltage wires shall be wired with Class I Wiring.

RECEIVING
CAUTION
(Ref. page)
•Do not install or operate any inverter which is damaged or
has missing parts.
Failure to observe this caution may result in personal injury or
equipment damage. 15
MOUNTING
CAUTION
(Ref. page)
•Lift the cabinet by the heatsink. When moving the
unit, never lift by the plastic case or the terminal covers.
Otherwise, the main unit may be dropped causing damage
to the unit. 17
•Mount the inverter on nonflammable material (i.e. metal).
Failure to observe this caution can result in a fire. 17
•When mounting units in an enclosure, install a fan or
other cooling device (open chasis to keep the intake air
temperature below 50: (122<).
Overheating may cause a fire or damage to the unit. 18
•The VS mini generates heat. For effective cooling,
mount it vertically.
Refer to the figure in “Mounting Dimensions”on page 18.

•Never touch the terminals while current is flowing, even
during inverter stopping.
Failure to observe this warning can result in an electric shock.
•When the fault retry function is selected, stand clear of
the inverter or the load, since it may restart suddenly
after being stopped.
(Construct machine system, so as to assure safety for personnel,
even if the inverter should restart.)
Failure to observe this
warning can result in personal injury.
53
•When continuous operation after power recovery is
selected, stand clear of the inverter or the load, since
it may restart suddenly after being stopped.
(Construct machine system, so as to assure safety for personnel,
even if the inverter should restart.)
Failure to observe this
warning can result in personal injury.
48
•Since the digital operator stop button can be disabled
by a function setting, install a separate emergency
stop switch.
Failure to observe this warning can result in personal injury.
•If an alarm is reset with the operation signal ON, the inverter
restarts automatically. Only reset the alarm after verifying
that the operation signal is OFF.
Failure to observe this warning can result in personal injury.

MAINTENANCE AND INSPECTION
CAUTION
(Ref. page)
•Never touch the heatsink since the temperature is very high.
Failure to observe this caution can result in harmful burns
to the body.
•Since it is easy to change operation speed from low to
high speed, verify the safe working range of the motor
and machine before operation.
Failure to observe this caution can result in personal injury
and machine damage.
•Install a holding brake separately if necessary.
Failure to observe this caution can result in personal injury.
•If using an Inverter with an elevator, take safety measures on the
elevator to prevent the elevator from dropping.
Failure to observe this caution can result in personal injury.
•Do not change signals during operation.
The machine or the inverter may be damaged.
•All the constants of the inverter have been preset
at the factory. Do not change the settings unnecessarily.
The inverter may be damaged. 27
WARNING
•Never touch high-voltage terminals in the inverter.
Failure to observe this warning can result in an electric shock.
• Disconnect all power before performing maintenance or inspection.
Then wait at least one minute after the power supply is disconnected
and all LEDs and CHARGE LED are extinguished.
The capacitors are still charged and can be dangerous.

10
WARNING
•Never modify the product.
Failure to observe this warning can result in an electric shock or personal
injury and will invalidate the guarantee.
WARNING
(Ref. page)
•Do not perform withstand voltage test on any part
of the VS mini.
This electronic equipment uses semiconductors and is
vulnerable to high voltage.
•Only authorized personnel should be permitted to perform
maintenance, inspections or parts replacement.
[Remove all metal objects (watches, bracelets, etc.)
before operation.]
(Use tools which are insulated against electric shock.)
Failure to observe this warning can result in an electric shock.
84
CAUTION
(Ref. page)
•The control PC board employs CMOS ICs.
Do not touch the CMOS elements.
They are easily damaged by static electricity.

on the front cover surface to
direction 1 to remove it. Then
press the right and left sides to
direction 2 and lift the front cover
to direction 3.

the front cover into the groove of
the inverter, and press the lower
part of the front cover onto the
plastic case until the cover snaps
shut. Then, tighten the screws.
Removing and Mounting Digital Operator and Covers
• Removing option cover
After removing front cover,
remove the option cover to
direction 2 with section A as a
supporting point.
• Mounting option cover
Mount the terminal cover in the
descending order of the above
procedure for removal.
• Removing upper/bottom covers
After removing front cover, lift
the covers to direction 1.
• Mounting upper/bottom covers
Mount the front cover in the
descending order of the above
procedure for removal.

4. WIRING
Wiring Instructions
(1) Always connect the power input terminals R/L1, S/L2, and T/L3 (R/L1,
S/L2 for single-phase) and power supply via a molded-case circuit
braker (MCCB) or a fuse. Never connect them to terminals
U/T1,V/T2,W/T3, –, +1 or +2.
Refer to page 108 for recommended peripheral devices. For single-
phase inverters, always use terminals R/L1 and S/L2. Never connect to
terminal T/L3.
Inverter Power Supply Connection Terminals
(2) Connect the motor wiring to terminals U/T1, V/T2 and W/T3 on the
main circuit output side (bottom of the inverter).
(3) If the wiring distance between inverter and motor is long, reduce the
inverter carrier frequency. For details, refer to “Reducing motor noise
or leakage current (n46)”on page 57.
(4) Control wiring must be less than 50m (164ft) in length and separate from
the power wiring. Use twisted-pair shielded wire when inputting the
frequency signal externally.
(5) Tighten the screws on the main circuit and control circuit terminals.
(6) Do not connect or disconnect wiring, or perform signal check while the
power supply is turned ON.
(7) For 400V class inverters, make sure to ground the supply neutral to con-
form to CE requirements.
(8) Only basic insulation to meet the requirements of protection class 1 and
overvoltage category II is provided with control circuit terminals.
Additional insulation may be necessary in the end product to conform to
CE requirements.
(9) A closed-loop connector should be used when wiring to the main circuit
terminal.
(10) Voltage drop should be considered when determining wire size.
Voltage drop can be calculated using the following equation:
Phase-to phase voltage drop (V)
= √3× wire resistance (Ω/km) ×wiring distance (m) ×current (A) ×10-3
Select a wire size so that voltage drop will be less than 2% of the normal
rated voltage.
