Safety Precautions
Caution
Do not use one found damaged or deformed when unpacked, otherwise, fire, failure or erratic operation might be caused.
Do not shock the product by dropping or tipping it over, otherwise, it might be damaged or troubled.
Follow the directions of the operating instructions and manual when mounting the product.
If mounting is improper, the product might drop or develop problems or erratic operations.
Use the rated voltage and current mentioned in the operating instructions and manual. Use beyond the rated values
might cause fire, erratic operation or failure.
Operate (keep) in the environment specified in the operating instructions and manual. High temperature, high humidity,
condensation, dust, corrosive gases, oil, organic solvents, excessive vibration or shock might cause electric shock, fire,
erratic operation or failure.
Select a wire size to suit the applied voltage and carrying current. Tighten the wire terminals to the specified torque.
Inappropriate wiring or tightening might cause fire, malfunction or failure, or might cause the product to drop from its
mounting.
Contaminants, wiring chips, iron powder or other foreign matter must not enter the device when installing it, otherwise,
fire, accident, erratic operation or failure might occur.
Remove the dust-cover seals of modules or units after wiring, otherwise, fire, accident, erratic operation or failure might
occur.
Connect the ground terminal to the ground, otherwise, electric shock or erratic operation might occur.
Periodically make sure the terminal screws and mounting screws are securely tightened.
Operation at a loosened status might cause fire or erratic operation.
Put the furnished connector covers on unused connectors, otherwise, erratic operation or failure might occur.
Put the furnished terminal covers on the terminal blocks, otherwise, electric shock or fire might occur.
Sufficiently make sure of safety before program change, forced output, starting, stopping or anything else during a run.
Wrong operation might break or cause problems to the machine
Engage the loader connector in a correct orientation, otherwise, an erratic operation might occur.
Before touching the PLC, discharge any static electricity that may have been collected on your body. To discharge it,
touch a grounded metallic object. Static electricity might cause erratic operation or failure.
Be sure to install the electrical wiring correctly and securely, observing the directions of the operating instructions and
manual. Wrong or loose wiring might cause fire, accident or failure.
When disengaging the plug from the outlet, do not pull the cord, otherwise, break of cable might cause fire or failure.
Do not attempt to change system configurations (such as installing or removing I/O modules) while the power is ON,
otherwise, erratic operation or failure might occur.
Do not attempt to repair the module by yourself, but contact your Fuji Electric agent. When replacing the batteries,
correctly and securely connect the battery connectors, otherwise, fire, accident or failure might occur.
Do not remodel or disassemble the product, otherwise, failure might occur.
Follow the regulations of industrial wastes when the device is to be discarded.
The modules covered in these operating instructions have not been designed or manufactured for use in equipment or
systems which, in the event of failure, can lead to loss of human life.
If you intend to use the modules covered in these operating instructions for special applications, such as for nuclear
energy control, aerospace, medical or transportation, please consult your Fuji Electric agent.
Be sure to provide protective measures when using the module covered in these operating instructions in equipment
which, in the event of failure, can lead to loss of human life or other grade results.
External power supply (such as 24 V DC power supply) which is connected to DC I/O should be strongly isolated from
AC power supply. (Use of EN60950 conforming power supply is recommended.) Otherwise, accident or failure might
be caused.
