Safety Precautions
Safety Precautions
Indications and Meanings of Safety Information
In this user's manual, the following precautions and signal words are used to provide information to ensure the
safe use of the 3G3MX Inverter.
The information provided here is vital to safety. Strictly observe the precautions provided.
Meanings of Signal Words
Indicates an imminently hazardous situation which, if not avoided,
WARNING
CAUTION
Alert Symbols in this Document
is likely to result in serious injury or may result in death. Additionally
there may be severe 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 put on or take off the Digital Operator•control circuit terminal block•terminal block cover
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.
(200-V class: type-D grounding, 400-V class: type-C grounding)
Do not remove the terminal block cover during the power supply and 5 minutes after the power
shutoff.
Doing so may result in a serious injury due to an electric shock.
Do not operate the Digital Operator or switches with wet hands. Doing so may result in a serious
injury due to an electric shock.
Do not change wiring, mode change switches, optional devices or replace cooling fans while power
is being supplied.
Doing so may result in a serious injury due to an electric shock.
5
Safety Precautions
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.
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
Take safety precautions such as setting up a molded-case circuit 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 this product.
Doing so may result in an injury.

Precautions for Safe Use
Precautions for Safe Use
Installation and Storage
Do not store or use the product in the following places.
•Locations subject to direct sunlight.
•Locations subject to ambient temperature exceeding the specifications.
•Locations subject to relative humidity exceeding the specifications.
•Locations subject to condensation due to severe temperature fluctuations.
•Locations subject to corrosive or flammable gases.
•Locations subject to exposure to combustibles.
•Locations subject to dust (especially iron dust) or salts.
•Locations subject to exposure to water, oil, or chemicals.
•Locations subject to shock or vibration.
Transporting, Installation, and Wiring
•Do not drop or apply strong impact on the product. Doing so may result in damaged parts or malfunction.
•Do not hold by the terminal cover, but hold by the fins during transportation.
•Do not connect an AC power supply voltage to the control input/output terminals. Doing so may result in
damage to the product.
•Be sure to tighten the screws on the terminal block securely.
Wiring work must be done after installing the unit body.
•Do not connect any load other than a three-phase inductive motor to the U, V, and W output terminals.
•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.
Operation and Adjustment
•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.
•Provide a separate holding brake if necessary.
Maintenance and Inspection
•Be sure to confirm safety before conducting maintenance, inspection or parts replacement.
7
Precautions for Correct Use
Precautions for Correct Use
Installation
•Mount the product vertically on a wall or on a DIN Rail (optional) with the product's longer sides upright.
The material of the wall has to be noninflammable such as a metal plate.
Main Circuit Power Supply
•Confirm that the rated input voltage of the Inverter is the same as AC power supply voltage.
Error Retry Function
•Do not come close to the machine when using the error retry function because the machine may abruptly
start when stopped by an alarm.
•Be sure to confirm the RUN signal is turned off before resetting the alarm because the machine may
abruptly start.
Operation Stop Command
•Provide a separate emergency stop switch because the STOP key on the Digital Operator is valid only when
function settings are performed.
•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.
Product Disposal
•Comply with the local ordinance and regulations when disposing of the product.

Easy-to-use General-purpose Inverter with Vector Control Functions
Advanced Functions
High Starting Torque
With its vector control, the 3G3MX Series has achieved high starting torque in excess of 200% at 1
Hz.
Trip Suppression
This Inverter features two trip suppression functions: "Overcurrent suppression function" to
suppress overcurrent trip during acceleration, and "Overvoltage LAD stop function" to suppress
overvoltage trip during deceleration. Therefore, the 3G3MX Series provides tough operational
capabilities regardless of the severe time setting of acceleration and deceleration.
Equipped with Communication Function
ModBus-RTU communication allows you to perform network operation at low cost.
Easy Operation
Adoption of Removable Control Circuit Terminal Block
Adoption of a removable control circuit terminal block substantially reduces onerous task of wiring
during the maintenance work.
Removable Digital Operator
The 3G3MX Series features a removable Digital Operator as a standard. By removing the Digital
Operator and connecting with the dedicated cable, you can operate the Inverter at hand and mount
it on the surface of the control panel.

Installation Environment
•Increased ambient temperatures will shorten the life of the Inverter.
•Keep the Inverter away from heating elements (such as a braking resistor, DC reactor, etc.).
If the Inverter is installed in a control panel, keep the ambient temperature within the range of the
specifications, taking dimensions and ventilation into consideration.
