Thank you for purchasing 3G3MX2 series type V1 Inverter.
To ensure the safe operation, please be sure to read the safety
precautions provided in this document along with all of the user
manuals for the inverter. Please be sure you are using the most
recent versions of the user manuals. Keep this instruction manual
and all of the manuals in a safe location and be sure that they are
readily available to the final user of the products.
In this user’s Manual, the following precautions and signal words
are used to provide information to ensure the safe use of the
3G3MX2 Multi-function Compact Inverter.
The information provided here is vital to safety. Strictly observe
the precautions provided.
Meanings of Signal Words
Indicates a potentially hazardous situation which,
WARNING

Alert Symbols in this Document
if not avoided, will result in minor or moderate injury,
or may result in serious injury or death. Additionally
there may be significant property damage.
Indicates a potentially hazardous situation which,
if not avoided, may result in minor or moderate
injury or in property damage.
WARNING
Turn off the power supply and implement wiring correctly.
Not doing so may result in a serious injury due to an electric shock.
Wiring work must be carried out only by qualified personnel. Not
doing so may result in a serious injury due to an electric shock.
Do not change wiring and slide switches, put on or take off Operator
and optional devices, replace cooling fans while the input power is being
supplied. Doing so may result in a serious injury due to an electric shock.
Be sure to ground the unit. Not doing so may result in a serious injury
due to an electric shock or fire.
(200V class:type-D grounding, 400V class:type-C grounding)
Do not remove the front cover during the power supply and 10 minutes
after the power shutoff. Doing so may result in a serious injury due to
an electric shock.
Do not operate the Operator or switches with wet hands.
Doing so may result in a serious injury due to an electric shock.
Inspection of the Inverter must be conducted after the power supply has
been turned off. Not doing so may result in a serious injury due to an
electric shock.
The main power supply is not necessarily shut off even if the emergency
shut off function is activated.
Do not touch the Inverter fins, braking resistors and the motor, which
become too hot during the power supply and for some time after the
power shutoff. Doing so may result in a burn.
CAUTION
Do not connect resistors to the terminals (+1, P/+2, N/-) directly.
Doing so might result in a small-scale fire, heat generation or damage
to the unit.
Install a stop motion device to ensure safety. Not doing so might result
in a minor injury. (A holding brake is not a stop motion device designed
to ensure safety.)
Be sure to use a specified type of braking resistor / regenerative
braking unit. In case of a braking resistor, install a thermal relay that
monitors the temperature of the resistor. Not doing so might result in a
moderate burn due to the heat generated in the braking resistor /
regenerative braking unit. Configure a sequence that enables the
Inverter power to turn off when unusual overheating is detected in the
braking resistor / regenerative braking unit.
The Inverter has high voltage parts inside which, if short-circuited,
might cause damage to itself or other property. Place covers on the
openings or take other precautions to make sure that no metal objects
such as cutting bits or lead wire scraps go inside when installing and
wiring.
Take safety precautions such as setting up a molded-case circut
breaker(MCCB) that matches the Inverter capacity on the power
supply side. Not doing so might result in damage to property due to
the short circuit of the load.
Do not dismantle, repair or modify the product.
Doing so may result in an injury.
Precautions for Safe Use
Installation and Storage
Do not store or use the product in the following places.
x
Locations subject to direct sunlight.
x
Locations subject to ambient temperature exceeding the specifications.
x
Locations subject to relative humidity exceeding the specifications.
x
Locations subject to condensation due to severe temperature fluctuations.
x
Locations subject to corrosive or flammable gases.
x
Locations subject to exposure to combustibles.
x
Locations subject to dust (especially iron dust) or salts.
x
Locations subject to exposure to water, oil, or chemicals.
x
Locations subject to shock or vibration.
Transporting, Installation and Wiring
x
Do not drop or apply a strong impact on the product.
Doing so may result in damaged parts or malfunction.
x
Do not hold by the front cover and terminal cover, but hold by the fins
during transportation.
x
Confirm that the rated input voltage of the Inverter is the same as AC
power supply voltage.
x
Do not connect an AC power supply voltage to the control input / output
terminals. Doing so may result in damage to the product.
x
Be sure to tighten the screws on the terminal block securely. Wiring work
must be done after installing the unit body.
x
Do not connect any load other than a three-phase inductive motor to the
U, V and W output terminals.
x
Take sufficient shielding measures when using the product in the following
locations. Not doing so may result in damage to the product.
Locations subject to static electricity or other forms of noise.
Locations subject to strong magnetic fields.
Locations close to power lines.
x
If a parameter is set incorrectly when starting up, adjusting, maintaining,
or replacing, an unexpected operation may occur. Perform the operation
after enough confirmation.
x
When using DriveProgramming, confirm that the program data is
downloaded normally before starting operation.
Operation and Adjustment
x
Be sure to confirm the permissible range of motors and machines before
operation because the inverter speed can be changed easily from low to
high.
x
Provide a separate holding brake if necessary.
x
If the DriveProgramming stops during multi-function output, the output
status is held. Take safety precautions such as stopping peripheral
devices.
x
Even if the inverter power supply is turned off, the counter-electromotive
force occurs while the PM motor rotates, which may result in electric shock.
Do not remove the terminal block cover of the inverter until the PM motor
stops.
x
Be sure to confirm the RUN signal is turned off before resetting the alarm
because the machine may abruptly start.
Maintenance and Inspection
x
Be sure to confirm safety before conducting maintenance,
inspection or parts replacement.
x
The capacitor service life is influenced by the ambient temperature.
Refer to "Product Life Curve" described in the User’s manual. When a
capacitor reaches the end of its service life and does not work as the
product, you need to replace the capacitor.
Precautions for Correct Use
Installation
x
Mount the product vertically on a wall with the product’ s longer sides
upright.
The material of the wall has to be nonflammable such as a metal plate.
Restart Selection Function
x
Do not come close to the machine when using the restart selection function
(b001, b008)
because the machine may abruptly start when stopped by
an alarm.
Deceleration Stop Function
x
Do not come close to the machine when selecting reset in the deceleration
stop function (b050) because the machine may abruptly start after the
power is turned on.
Operation Stop Command
x
Provide a separate emergency stop switch because the STOP Key on the
Operator is valid only when function settings are performed.
x
When checking a signal during the power supply and the voltage is
erroneously applied to the control input terminals, the motor may start
abruptly. Be sure to confirm safety before checking a signal.
Motor Overload Protection
x
For the motor overload protection, be sure to set the rated current of your
motor to the Electronic Thermal Level (b012/b212) and PM Motor Rated
Current (H105).
Maintenance and Parts Replacement
x
Inverters contain components and will operate properly only when each
component operates normally. Some of the electrical components require
maintenance depending on application conditions.
Periodic inspection and replacement are necessary to ensure proper
long-term operation of Inverters. (Quoted from The Recommendation for
Periodic Maintenance of a General-purpose Inverter published by JEMA.)
Product Disposal
x
Comply with the local ordinance and regulations when disposing of the
product.
