NOTATION FOR SAFETY PRECAUTIONS
Read this instruction manual thoroughly before installation, operation, mainte-
nance, or inspection of the V7 IP65. In this manual, safety precautions are classi-
fied 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
minor or moderate injury or damage to equipment.
It may also be used to alert against unsafe practices.
Even items classified as cautions may result in serious accidents in some situa-
tions. Always follow these important precautions.
: Indicates information to insure proper operation.
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.

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.
18
(Ref. page)
• Mount the Inverter on nonflammable material
(i.e., metal).
Failure to observe this caution may result in a fire.
23
• When mounting Inverters please insure that
ambient temperature is below below 40 °C
(105 °F)
Overheating may cause a fire or damage the Inverter.
23
• The V7 IP65 generates heat. For effective cool-
ing, mount it vertically.
Refer to the figure in Choosing a Location to
Mount the Inverter on page 24.

WIRING
(Ref. page)
• Only begin wiring after verifying that the power
supply is turned OFF.
Failure to observe this warning may result in an elec-
tric shock or a fire.
27
• Wiring should be performed only by qualified
personnel.
Failure to observe this warning may result in an elec-
tric shock or a fire.
27
• When wiring the emergency stop circuit, check
the wiring thoroughly before operation.
Failure to observe this warning may result in injury.
27
• Always ground the ground terminal accord-
ing to the local grounding code.
Failure to observe this warning may result in an elec-
tric shock or a fire.
32
• If the power supply is turned ON while the FWD
(or REV) Run Command is being given, the
motor will start automatically.
Turn the power supply ON after verifying that
the RUN signal is OFF.
Failure to observe this warning may result in injury.
35
• 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.
107
WARNING

5
(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.
27
• Do not perform a withstand voltage test on the
Inverter.
Performing withstand voltage tests may damage
semiconductor elements.
27
• To connect a Braking Resistor, Braking Resistor
Unit, or Braking Unit, follow the procedure
described in this manual.
Improper connection may cause a fire.
32
• 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.
27
• Never connect the AC main circuit power supply
to output terminals U/T1, V/T2, W/T3, B1, B2, -,
+1, or +2.
The Inverter will be damaged and the guarantee will
be voided.
27
• 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.
27
• Do not perform signal checks during operation.
The machine or the Inverter may be damaged.
27
• To store a constant with an Enter Command by
communications, be sure to take measures for
an emergency stop by using the external termi-
nals.
Delayed response may cause injury or damage the
machine.

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 or the covers while current is
flowing.
Failure to observe this warning may result in an elec-
tric shock.
36
• Never operate the Digital Operator or DIP
switches with wet hands.
Failure to observe this warning may result in an elec-
tric shock.
36
• Never touch the terminals while current is flow-
ing, even if the Inverter is stopped.
Failure to observe this warning may result in an elec-
tric shock.
36
• 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.
79
• 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.
74
• 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.
93
WARNING

7
(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.
35
• 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.
107
• If n001=5, a Run Command can be received
even while changing a constant. If sending a
Run Command while changing a constant, such
as during a test run, be sure to observe all
safety precautions.
Failure to observe this warning may result in injury.
44, 49
(Ref. page)
• Never touch the heatsinks, which can be
extremely hot.
Failure to observe this caution may result in harmful
burns to the body.
36
• It is easy to change operation speed from low to
high. Verify the safe working range of the motor
and machine before operation.
Failure to observe this caution may result in injury
and machine damage.
36
• Install a holding brake separately if necessary.
Failure to observe this caution may result in injury.

• If using an Inverter with an elevator, take safety
measures on the elevator to prevent the eleva-
tor from dropping.
Failure to observe this caution may result in injury.
181
• Do not perform signal checks during operation.
The machine or the Inverter may be damaged.
36
• All the constants set in the Inverter have been
preset at the factory. Do not change the settings
unnecessarily.
The Inverter may be damaged.

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.
186
• Disconnect all power before performing mainte-
nance or inspection, and then wait at least one
minute after the power supply is disconnected.
For 400 V Class Inverters, confirm that all indi-
cators are OFF before proceeding.
If the indicators are not OFF, the capacitors are still
charged and can be dangerous.
186
• Do not perform a withstand voltage test on any
part of the V7 IP65.
The Inverter is an electronic device that uses semi-
conductors, and is thus vulnerable to high voltage.
186
• 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.
