nance, or inspection of the Varispeed V7. In this manual, safety precautions are
classified as either warnings or cautions and are indicated as shown below.
Indicates a potentially hazardous situation which, if not avoided, may result in
death or serious injury.
Indicates a potentially hazardous situation which, if not avoided, may result in

PRECAUTIONS 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 turned OFF. To prevent electric shock, disconnect all power before ser-
vicing the Inverter, and then wait at least one minute after the power sup-
ply is disconnected. Confirm that all indicators are OFF before
proceeding.
• Do not perform a withstand voltage test on any part of the Inverter. The
Inverter is an electronic device that uses semiconductors, and is thus vul-
nerable to high voltage.
• Do not remove the Digital Operator or the blank cover unless the power
supply is turned OFF. Never touch the printed circuit 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, 250 V maximum (200 V Class
Inverters) or 18,000 RMS symmetrical amperes, 480 V maximum (400 V
Class Inverters).
PRECAUTIONS 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 con-
form 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
• Use 75°C copper wire or equivalent.
Low voltage wires must be wired with Class I Wiring.

RECEIVING THE PRODUCT
MOUNTING
(Ref. page)
• Do not install or operate any Inverter that is
damaged or has missing parts.
Failure to observe this caution may result in injury or
equipment damage.
19
(Ref. page)
• Lift the Inverter by the heatsinks. When moving
the Inverter, never lift it by the plastic case or the
terminal cover.
Otherwise, the main unit may fall and be damaged.
24
• Mount the Inverter on nonflammable material
(i.e., metal).
Failure to observe this caution may result in a fire.
24
• When mounting Inverters in an enclosure, install
a fan or other cooling device to keep the intake
air temperature below 50°C (122°F) for IP20
(open chassis type), or below 40°C (105°F) for
NEMA 1 (TYPE 1), IP20 (top closed type).
Overheating may cause a fire or damage the Inverter.
24
• The Varispeed V7 generates heat. For effective
cooling, mount it vertically.
Refer to the figure in Mounting Dimensions on
page 25.

WARNING

6
(Ref. page)
• Verify that the Inverter rated voltage coincides
with the AC power supply voltage.
Failure to observe this caution may result in personal
injury or a fire.
• Do not perform a withstand voltage test on the
Inverter.
Performing withstand voltage tests may damage
semiconductor elements.

Unit, or Braking Unit, follow the procedure
described in this manual.
Improper connection may cause a fire.
36
• Always tighten terminal screws of the main cir-
cuit and the control circuits.
Failure to observe this caution may result in a mal-
function, damage, or a fire.
28
• Never connect the AC main circuit power supply
to output terminals U/T1, V/T2, or W/T3.
The Inverter will be damaged and the guarantee will
be voided.
28
• Do not connect or disconnect wires or connec-
tors while power is applied to the circuits.
Failure to observe this caution may result in injury.
• Do not perform signal checks during operation.
The machine or the Inverter may be damaged.

OPERATION
(Ref. page)
• Only turn ON the input power supply after con-
firming that the Digital Operator or blank cover
(optional) are in place. Do not remove the
Digital Operator, remove the covers, or set
rotary switches while current is flowing.
Failure to observe this warning may result in an elec-
tric shock.
• Never operate the Digital Operator or DIP
switches with wet hands.
Failure to observe this warning may result in an elec-
tric shock.
• Never touch the terminals while current is flow-
ing, even if the Inverter is stopping.
Failure to observe this warning may result in an elec-
tric shock.
• When the fault retry function is selected, stand
clear of the Inverter or the load. The Inverter
may restart suddenly after stopping.
(Construct the system to ensure safety, even if the
Inverter should restart.) Failure to observe this warn-
ing may result in injury.
148
• When continuous operation after power recov-
ery is selected, stand clear of the Inverter or the
load. The Inverter may restart suddenly after
stopping.
(Construct the system to ensure safety, even if the
Inverter should restart.) Failure to observe this warn-
ing may result in injury.
144
• The Digital Operator stop button can be dis-
abled by a setting in the Inverter. Install a sepa-
rate emergency stop switch.
Failure to observe this warning may result in injury.
WARNING

(Ref. page)
• If an alarm is reset with the operation signal ON,
the Inverter will restart automatically. Reset an
alarm only after verifying that the operation sig-
nal is OFF.
Failure to observe this warning may result in injury.
40
• When the 3-wire sequence is set, do not make
the wiring for the control circuit unless the multi-
function input terminal parameter is set.
Failure to observe this warning may result in injury.
159
(Ref. page)
• Never touch the heatsinks, which can be
extremely hot.

MAINTENANCE AND INSPECTION
(Ref. page)
• Never touch high-voltage terminals on the
Inverter.
Failure to observe this warning may result in an elec-
trical shock.
• Disconnect all power before performing mainte-
nance or inspection, and then wait at least one
minute after the power supply is disconnected.
Confirm that all indicators are OFF before pro-
ceeding.
If the indicators are not OFF, the capacitors are still
charged and can be dangerous.
• Do not perform withstand voltage test on any
part of the Varispeed V7.
The Inverter is an electronic device that uses semi-
conductors, and is thus vulnerable to high voltage.
• Only authorized personnel should be permitted
to perform maintenance, inspection, or parts
replacement.
(Remove all metal objects (watches, bracelets, etc.)
before starting work.)
(Use tools which are insulated against electrical
shock.)
Failure to observe these warnings may result in an
electric shock.

WARNING

10
OTHERS
(Ref. page)
• The control PCB employs CMOS ICs.
Do not touch the CMOS elements.
They are easily damaged by static electricity.
• Do not connect or disconnect wires, connectors,
or the cooling fan while power is applied to the
circuit.
Failure to observe this caution may result in injury.
202
• Never modify the product.
Failure to observe this warning may result in an electrical shock or
injury and will void the guarantee.
• Do not subject the Inverter to halogen gases, such as fiuorine,
chlovine, bromine, and iodine, at any time even during trans-
portation or installation.
Otherwise, the Inverter can be damaged or interior parts burnt.
