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

Motor Overload Protection
3G3JX Inverters provide solid state motor overload protection, which
depends on the proper setting of the following parameters .
x
b012 : electronic overload protection
x
b212 : electronic overload protection, 2nd motor
Set the rated current [Amperes] of the motor(s) with the above
parameters. The setting range is 0.2 rated current to 1.0 rated current.
When two or more motors are connected to the Inverter, they cannot be
protected by the electronic overload protection. Install an external thermal
relay on each motor.
