Safety Precautions
WARNING
Turn off the power supply and implement wiring correctly.
Not doing so may result in a serious injury due to an electric sho ck.
Wiring work must be carried out only by qualified personnel.
Not doing so may result in a serious injury due to an electric sho ck.
Do not change wiring and slide switches (SW1 to SW6), put on or take off
Operator and optional devices, replace cooling fans while the i nput 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 15
minutes*1*2 after the power shut off. Doing so may result in a serio us 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.
*1. 10 minutes: For models 3G3RX2-A2004 to A2220 and 3G3RX2-A4007 to A4220
*2. 15 minutes: For models 3G3RX2-A2300 to A2550 and 3G3RX2-A4300 to B413K

Safety Precautions
Be sure to confirm safety before conducting mainte nance, inspection or parts
replacement.
Do not connect resistors to the terminals (PD/+1, P/+, 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 s o might r esult i n a mode rate bur n due
to the heat generated in the braking resistor/regenerati ve 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 du e to th e short ci rcuit of the
load.
Do not dismantle, repair or modify the product.
Doing so may result in an injury.
If a parameter is set incorrectly when starting up, adjusting, maintaining, or
replacing, an unexpected operation may occur.
CAUTION
If the DriveProgramming stops during multi-funct ion output, the output status
is held. Take safety precautions such as stopping peripheral devices.

• 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.
• When using DriveProgramming, confirm that the program data is downloaded normally before
starting operation.
7
Precautions for Safe Use
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.
• If the clock command is u sed in DriveP rogramming , an un expecte d operat ion may occur du e to we ak
battery. Take measures such as detecting a weak battery by [E042] RTC Error and stopping the
inverter or programs. When the LCD Operator is removed or disconnected, DriveProgramming is in a
waiting status by the clock command.
• 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 you enable "restart" setting that results in automatic start
after a deceleration stop, (bA-30, bb-20, bb-21) the machine may abruptly start aft er 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.
• Check whether the motor rotation direction is correct and unusual sound or vibration occurs during
operation.
Maintenance and Inspection
• 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 operators and wasted batteries, follow the applicable ordinances of your
local government. When disposing of the battery, insulate it using tape.
The following display must be indi cated when products usin g lithium primary batteri es (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/hazardou s waste / p erc hl ora te
Label or mark the above display on the ex terior of all outer shi pping packages of your products when exporting your p roducts w hich the li thium prim ary batter ies (with m ore than 6 ppb
of perchlorate) are installed to the State of California, USA.
• 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 an d also replace the battery acc ording to th e method descri bed
in this manual.
• When the display of LCD Operator can not be recognized due to the service life, replace the LCD
Operator.

Installation conditions
■Equipment Peripheral Dimension Conditions
Please note the installation method, the direction of installation!
• If the inverter is not installed vertically, its cooling performance may be degraded and tripping or
inverter damage may result.
• Install the inverter vertically and securely with screws or bolts on a surface that can bear the inverter
weight and is free from vibrations.
Surface on which to install the inverter
• The inverter will reach a high temperature (up to about 150°C) during operation. Install the inverter on
a vertical wall surface made of n onflamma ble mat erial (e. g., met al) t o avoid t he risk of fire. In additi on
be sure to confirm the structure to bear the Inverter weight.
• Keep sufficient distance between the inverter and other heat sources (e.g., braking resistors and
reactors) so that the heat discharged from the heat sources does not affect the inverter.

■Humidity
Avoid installing the inverter in a place where the relative humidity goes above or below the allowable
range (20% to 90% RH), as defined by the standard inverter specification. Avoid a place where the
inverter is subject to condensation.
Condensation inside the inverter will result in short circuits and malfunctioning of electronic parts. Also
avoid places where the inverter is exposed to direc t s un ligh t.
