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 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

6
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.

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 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
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.

Overview
Compact Simplified Inverter for Customer's Environment and
Application Demands
Simple Wiring and Easy Installation
The main circuit adopts upper/lower wiring as with a conductor. In addition, the side-by-side
mounting of the Inverters and the built-in zero-phase reactor contribute to space saving in control
panel.
Wide Ranging Capacity and Power Supply
In spite of its compact size, the 3G3JX Inverter provides a wide ranging capacity from 0.2 to 7.5 kW.
Moreover, the three-phase 200 V, three-phase 400 V, andsingle/three-phase 200 V common types
are made to meet the power supply specifications for use outside Japan.
PID Function
The PID function is featured for the easier control of the fan and pump. It helps to control airflow and
pressure.
Emergency Shutoff Function
Switching the dedicated switch (S8) changes from the multi-function input (input 3) to the
emergency shutoff input. You can directly turn off a motor control power module without operating
the software.
Compliance With All Standards
The 3G3JX Series has achieved compliance with CE and UL/cUL.
The RoHS Directive
The standard model meets the requirements of the RoHS Directive.
Noise and Harmonics Suppression Option
The three-phase models incorporate a zero-phase reactor (radio noise filter) as a standard
specification.
For the single/three-phase common type, optional suppression is available.
When the optional DC reactor is added, the 3G3JX Series will also meet the requirements specified
by the Ministry of Land, Infrastructure, Transport and Tourism of Japan.
Handles a Variety of I/O Signals
The 3G3JX Series can handle a variety of I/O signals for wide-ranging applications.
•Analog voltage input: 0 to 10 V
•Analog current input: 4 to 20 mA
