Safety Precautions
High-function General-purpose Inverter 3G3RX-V1 User’s Manual (I578-E1)
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 (SW1), 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.
(200-V class: type-D grounding, 400-V class: type-C grounding)
Do not remove the terminal cover during the power supply and 10 minutes after the power shut off.
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 was 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 shut off. Doing so may result in a burn.
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 over eating 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 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
12 High-function General-purpose Inverter 3G3RX-V1 User’s Manual (I578-E1)
Precautions for Safe Use
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.
•Do not drop or apply strong impact on the product. Doing so may result in damaged parts or
malfunction.
•Do not hold by the front cover and terminal cover, but hold by the fins during transportation.
•Confirm that the rated input voltage of the inverter is the same as AC power supply voltage.
•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.
•If a parameter is set incorrectly when starting up, adjusting, maintaining, or replacing, an unexpected
operation may occur. Perform the operation after enough confirmation.
•When using DriveProgramming, confirm that the program data is downloaded normally before
starting operation.

Precautions for Safe Use
High-function General-purpose Inverter 3G3RX-V1 User’s Manual (I578-E1)
•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.
•If the DriveProgramming stops during multi-function output, the output status is held. Take safety
precautions such as stopping peripheral devices.
•If the clock command is used in DriveProgramming, an unexpected operation may occur due to weak
battery. Take measures such as detecting a weak battery by a check that the clock data returns to the
initial setting and stopping the inverter or programs. When the LCD Digital Operator is removed or
disconnected, DriveProgramming is in a waiting status by the clock command.
•Be sure to confirm safety before conducting maintenance, inspection or parts replacement.
•The capacitor service life is influenced by the ambient temperature. Refer to “Smoothing Capacitor
Life Curve” described in the manual. When a capacitor reaches the end of its service life and does
not work as the product, you need to replace the capacitor.
•When disposing of LCD digital operators and wasted batteries, follow the applicable ordinances of
your local government. When disposing of the battery, insulate it using tape.
•Do not short + and –, charge, disassemble, heat, put into the fire, or apply strong impact on the
battery. The battery may leak, explode, produce heat or fire. Never use the battery which was applied
strong impact due to such as fall on the floor, it may leak.
•UL standards establish that the battery shall be replaced by an expert engineer. The expert engineer
must be in charge of the replacement and also replace the battery according to the method described
in this manual.
•When the display of LCD Digital Operator can not be recognized due to the service life, replace the
LCD Digital Operator.
Operation and Adjustment
Maintenance and Inspection
The following display must be indicated when products using lithium primary batteries (with
more than 6 ppb of perchlorate) are transport to or through the State of California, USA.
Perchlorate Material - special handling may apply.
See www.dtsc.ca.gov/hazardouswaste/perchlorate
The 3G3AX-OP05 has the lithium primary battery (with more than 6 ppb of perchlorate).
Label or mark the above display on the exterior of all outer shipping packages of your prod-
ucts when exporting your products which the 3G3AX-OP05 are installed to the State of Cali-

Precautions for Correct Use
14 High-function General-purpose Inverter 3G3RX-V1 User’s Manual (I578-E1)
Precautions for Correct Use
Mount the product vertically on a wall with the product’s longer sides upright.
The material of the wall must be noninflammable such as a metal plate.
•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.
•Be sure to confirm the RUN signal is turned off before resetting the alarm because the machine may
abruptly start.
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.
•Provide a separate emergency stop switch because the STOP Key on the 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.
•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.)
•When a cooling fan reaches the end of its service life, replace it.
Comply with the local ordinance and regulations when disposing of the product.
