Safety Precautions
II
WARNING
●For the entire system to function safely when the F805AT-CK becomes faulty or
malfunctions, provide a safety circuit outside the F805AT-CK.
●Before using the F805AT-CK as described below, make sure to consult with our sales
personnel.
- Use in environments not described in the operation manual.
- Use greatly impacting human lives and assets, such as medical devices, transport devices
entertainment devices, and safety devices.
●Do not disassemble, repair, or modify the F805AT-CK. Doing so may cause a fire or an
electric shock.
●Do not install in the following environments.
- Places containing corrosive gas or flammable gas.
- Where the product may be splashed with water, oil or chemicals.
●Do not connect a commercial power source directly to the signal input/output terminals.
●Be sure to ground the protective ground terminal.
●The attached AC cable is designed for domestic use in Japan, and its rating is 125V AC, 7A.
For use at voltages exceeding the rating and for overseas use, have a separate AC cable
prepared.
●Before performing the following, make sure that no power is applied.
- Attachment/detachment of connectors of options, etc.
- Wiring/connection of cables to the signal input/output terminals.
- Connection to the ground terminal.
●For connection to the signal input/output terminals, check the signal names and pin
assignment numbers, and then carry out wiring properly.
●The connection to the RS-485 terminal block must use the crimp contacts.
Do not connect it the open-wire line.
●After wiring, be sure to mount the attached terminal block cover. Otherwise, it may cause an
electric shock. (at the DC spec.)
●To take measures against lightning surge, install a lightning surge protector (optionally
available).
●Do not connect anything to unused terminal(s).
●Before applying power, carefully check the wiring, etc.
This sign forewarns the presence of hazards
that could result in serious injury or fatality
when incorrectly handled.

Safety Precautions
III
WARNING
●Use a power supply voltage and load within the specified and rated ranges.
●Do not damage the power cord. Doing so may cause fire or electric shocks.
●Do not touch any signal input/output terminal while applying power. Doing so may cause
electric shocks or malfunctions.
●If the cover of the main body is opened, it may cause an electric shock internally. Even if the
power is off, the internal capacitor is charged. Contact us for internal inspection or repair.
●In the case of smoke, an abnormal smell or strange sound, immediately turn off the power,
and disconnect the power cable.
●Lithium battery use in the F805AT-CK unit.
type: CR14250SE manufactured by Sanyo Electric, or equivalent
Voltage: 3 volts
Capacity: 850 mAh
This sign forewarns the presence of hazards
that could result in serious injury or fatality
when incorrectly handled.
Warning during startup and maintenance
CAUTION
●Use the F805AT-CK as it is incorporated in a control panel, etc.
●Do not install in the following environments:
- Locations where temperature or humidity exceeds specifications;
- Locations subjected to drastic temperature fluctuations or icing and condensing;
- Outdoors or locations above 2,000m;
- Locations exposed to direct sunlight;
- Locations subject to dust accumulation;
- Locations with poor ventilation;
- Locations with a lot of salt and metal powder;
- Locations where the main unit is subject to direct vibration and shock.
●Take adequate shielding measures when using at the following locations.
- Near a power line.
- Where a strong electric field or magnetic field is formed.
- Where static electricity, relay noise or the like is generated.
●Install the F805AT-CK as far away from devices generating high frequency, high voltage,
large current, surge, etc., as possible. Also, carry out wiring separately from their power
lines. Do not carry out parallel wiring and common wiring.
●Do not use it, broken down.
This sign forewarns the presence of hazards
that could result in personnel injury or property
damage when incorrectly handled.
Caution on installation

IV
About the power cable
CAUTION
●Tighten the screws for the signal input/output terminals at the specified torque.
If they are loose, shorts, fire or malfunctions may occur.
Tightening torque: 0.5N •m (at the DC spec.)
●For sensors, external inputs/outputs and options, use shielded cables.
●The temporary overvoltage applied to the power should not exceed 1500V.
●For turning on/off the power, be sure to keep intervals of 5 seconds or more.
●After power-on, make sure to warm up the F805AT-CK for at least 30 minutes or more before
use.
●If the F805AT-CK is not used by the specified method, its protective performance may be
impaired.
●Maintenance
- When performing maintenance, disconnect the power.
- Do not wipe with a wet rag, or with benzine, thinner, alcohol, etc. Doing so may cause
discoloration or deformation of the F805AT-CK. In the case of heavy contamination,
wipe off the contamination with a cloth after dipping it into a diluted neutral detergent
and wringing it well, and then wipe with a soft, dry cloth.
●When the F805AT-CK is shipped, spacers made of corrugated cardboard are used as
cushioning materials.
Though it is factory-designed so that shocks can sufficiently be absorbed, breakage may
result if shocks are applied when the spacers are reused for transportation. If you send the
F805AT-CK to us for repair, etc., take adequate measures against shocks by using
polyurethane materials, etc., separately.
●If you dispose of the product, handle it as industrial waste.
This sign forewarns the presence of hazards
that could result in personnel injury or property
damage when incorrectly handled.
