Precautions For Safe Use - Omron FQ2-S4 User Manual

The following points are important to ensure safety, so make sure that they are strictly observed.
1. Installation Environment
• Do not use the product in environments where it can be exposed to inflammable/explosive gas.
• To secure the safety of operation and maintenance, do not install the product close to high-voltage devices
and power devices.
• Install the product in such a way that its ventilation holes are not blocked.
• Tighten mounting screws at the torque specified in this manual.
2. Power Supply and Wiring
• The power supply voltage must be within the rated range (24 VDC ±10%), and an AC voltage must not be
used.
• Reverse connection of the power supply is not allowed. Do not short the load of the open collector output.
• The load must be within the rated range.
• High-voltage lines and power lines must be wired separately from this product. Wiring them together or
placing them in the same duct may cause induction, resulting in malfunction or damage.
• Use the products within the power supply voltages specified in this manual.
• Use the specified size of crimp terminals to wire connections. Do not connect wires that have been simply
twisted together directly to the power supply or terminal block.
• Use a DC power supply with safety measures against high voltages (safety extra low-voltage circuit).
• Use independent power sources for the products. Do not use a shared power source.
• Tighten mounting screws at the torque specified in this manual.
• Always turn OFF the power supply before connecting or disconnecting cables or the power supply wiring.
3. Battery
• Do not short the positive and negative terminals of the Battery.
• Do not use the Touch Finder in an environment that exceeds the operating temperature range of the Battery.
If the Touch Finder is used at temperatures that exceed the operating temperature range, the protective
device may activate and prevent charging.
• Do not connect the Battery directly to a power supply or car cigarette lighter socket.
• Do not use the Touch Finder with any other type of battery.
• Turn OFF the power supply immediately if the Battery leaks or produces an odor. Electrolyte leaked from the
Battery may ignite, possibly causing smoke, rupture, or fire.
• If during usage, charging, or storage, the Battery produces an odor, heats, becomes discolored, becomes
misshapen, or exhibits any other unusual conditions, remove it and do not use it. Continuing to use such a
Battery may result in the Battery heating, smoking, rupturing, or igniting.
• If the Touch Finder (FQ2-D31) will be installed permanently or semi-permanently, remove the Battery (FQ-
BAT1). If the rated temperature is exceeded with the Battery inserted, the protective circuit may activate and
stop the Touch Finder.
4. AC Adapter
• Use an AC cable that is suitable for the power supply and power voltage you are using.
• Do not touch the power plug with a wet hand. Doing so may result in electrical shock.
• If you notice an abnormal condition, such as smoke, abnormal heating of the outer surface, or a strange
odor, immediately stop using the AC Adapter, turn OFF the power, and remove the power plug from the
outlet.
Consult your dealer, as it is dangerous to attempt to repair the AC Adapter yourself.
• If the AC Adapter is dropped or damaged, turn OFF the power, remove the power plug from the outlet, and
contact your dealer. There is a risk of fire if you continue using the AC Adapter.
