Disclaimers

CHANGE IN SPECIFICATIONS

Product specifications and accessories may be changed at any time based on improvements and other

reasons.

It is our practice to change model numbers when published ratings or features are changed, or when

significant construction changes are made. However, some specifications of the products may be

changed without any notice. When in doubt, special model numbers may be assigned to fix or establish

key specifications for your application on your request. Please consult with your OMRON representative

at any time to confirm actual specifications of purchased products.

DIMENSIONS AND WEIGHTS

Dimensions and weights are nominal and are not to be used for manufacturing purposes, even when

tolerances are shown.

PERFORMANCE DATA

Performance data given in this manual is provided as a guide for the user in determining suitability and

does not constitute a warranty. It may represent the result of OMRON's test conditions, and the users

must correlate it to actual application requirements. Actual performance is subject to the OMRON

Warranty and Limitations of Liability.

ERRORS AND OMISSIONS

The information in this manual has been carefully checked and is believed to be accurate; however, no

responsibility is assumed for clerical, typographical, or proofreading errors, or omissions.

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 3G3JX Inverter.

The information provided here is vital to safety. Strictly observe the precautions provided.

Meanings of Signal Words

Alert Symbols in This Document

Indicates an imminently hazardous situation which, if not avoided,

is likelytoresultinseriousinjuryor 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

CAUTION

Turnoffthepowersupply and implementwiringcorrectly.Notdoing so mayresult ina seriousinjury

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.

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)

Donotremovethefrontcoverduringthe power supply and 5 minutes after thepowershutoff.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.

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 shutoff function is

activated.

Do not change wiring, mode change switches (S7, S8), optional devices or replace cooling fans

while the input power is being supplied.

Doing so may result in a serious injury due to an electric shock.

WARNING

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.

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 the product.

Doing so may result in an injury.

CAUTION

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 salt.

•Locations subject to exposure to water, oil, or chemicals.

•Locations subject to shock or vibration.

Transporting, Installation, and Wiring

•Do not drop or apply a strong impact on the product. Doing so may result in damaged parts or malfunction.

•Do not hold by the front 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.

Precautions for Correct Use

Installation

•Mount the product vertically on a wall or on a DIN track (optional) with the product's longer sides upright.

The material of the wall has to be nonflammable 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.

Non-Stop Function at Momentary Power Interruption

•Do not come close to the machine when selecting restart in the non-stop function at momentary power

interruption selection (b050) because the machine may abruptly start after the power is turned on.

Operation Stop Command

•Provideaseparateemergencystopswitchbecause the STOP key on the Digital Operator is valid onlywhen

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.
