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.

thoroughly before operation.
Failure to observe this warning can result in personal injury.
÷÷÷÷÷÷20
•For 400V class, make sure to ground the supply neutral.
Failure to observe this warning can result in an electric shock
or a fire. ÷÷÷÷÷÷÷÷÷÷÷÷÷÷÷÷÷÷÷÷÷÷÷÷÷÷÷÷÷÷÷÷÷÷÷÷÷÷÷÷÷÷÷÷÷÷÷÷24

CAUTION
(Ref. page)
•Verify that the inverter rated voltage coincides with the
AC power supply voltage.
Failure to observe this caution can result in personal injury
or a fire.
•Do not perform a withstand voltage test of the inverter.
It may cause semi-conductor elements to be damaged.
•Make sure to tighten terminal screws of the main circuit
and the control circuit.
Failure to observe this caution can result in a malfunction,
damage or
a fire.
÷÷÷÷÷÷÷÷÷÷÷÷÷÷÷÷÷÷÷÷÷÷÷÷÷÷÷÷÷÷÷÷÷÷÷÷÷÷÷÷÷20
•Never connect the AC main circuit power supply to
output terminals U/T1, V/T2, and W/T3.
The inverter will be damaged and invalidate the guarantee.
÷÷÷÷÷÷÷÷20
•Do not connect or disconnect wires or connectors
while power is applied to the circuit.
Failure to observe this caution can result in personal injury.

WARNING
(Ref. page)
•Only turn ON the input power supply after replacing
the front cover.
Do not remove the covers while current is flowing.
Failure to observe this warning can result in an electric shock.
•Never operate the digital operator or dip the switches
when your hand is wet.
Failure to observe this warning can result in an electric shock.
•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.

•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.

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.
