Warning Indications
Meaning of Product Safety Symbols
This product is not designed or rated for ensuring
safety of persons either directly or indirectly.
Do not use it for such purposes.
Do not use the product with voltage in excess of the
rated voltage.
Excess voltage may result in malfunction or fire.
Never use the product with an AC power supply.
Otherwise, explosion may result.
The following precautions must be observed to ensure safe
operation of the product. Doing so may cause damage or fire.
• Do not install the product in the following locations.
(1) Locations subject to direct sunlight
(2) Locations subject to condensation due to high humidity
(3) Locations subject to corrosive gas
(4) Locations subject to vibration or mechanical shocks exceeding
the rated values
(5) Locations subject to exposure to water, oil, chemicals
(6) Locations subject to steam
(7) Locations subject to strong magnetic field or electric field
• Do not use the product in environments subject to flammable or
explosive gases.
• Do not use the product in any atmosphere or environment that
exceeds the ratings.
• To secure the safety of operation and maintenance, do not install
the product close to high-voltage devices and power devices.
• High-voltage lines and power lines must be wired separately from
the product. Wiring them together or placing them in the same duct
may cause induction, resulting in malfunction or damage.
• Do not apply any load exceeding the ratings. Doing so may cause
damage or fire.
• Do not short the load. Doing so may cause damage or fire.
• Connect the load correctly.
• Do not miswire such as the polarity of the power supply.
• Do not use the product if the case is damaged.
• Burn injury may occur. The product surface temperature rises
depending on application conditions, such as the ambient
temperature and the power supply voltage. Attention must be paid
during operation or cleaning.
• When setting the sensor, be sure to check safety such as by
stopping the equipment.
• Be sure to turn off the power supply before connecting or
disconnecting wires.
• Do not attempt to disassemble, repair, or modify the product in any
way.
• When disposing of the product, treat it as industrial waste.
• Do not use the Sensor in water, rain, or outdoors.
• Process the unwired terminals so as not to contact other wiring or
devices.
• Connect the Sensor Head correctly. Otherwise, it might be broken
or catch fire.
• Do not connect any sensor heads differently designed from the
amplifier input specification (voltage/current range and current
consumption). Otherwise, it might be broken or catch fire.
• To use this device as connecting with each other, be sure to
connect with the same power supply and turn ON the power
simultaneously.
Using a separate power supply will influence the functions when
connecting the devices to use them.
• The maximum number of connectable amplifiers is different
depending on the current consumption of the sensor head. The
number of the amplifiers connected must be within the specified
limit. Otherwise, they might be broken or catch fire.
• If power is supplied from an external power source to the sensor,
excessive current flows to this product or sensor, so that the device
might be broken or catch fire. Use this product as supplying power
from it to the sensor.
• When connecting this device with a sensor, confirm product
performance well before using the product.
• UL Standard Certification
Only the sensors with Enhanced UL Certification Mark are certified
by UL. They are intended to be supplied by a "Class 2 circuit".
When used in United States and Canada, Please use the same
Class 2 source for input and output. The overcurrent protection
current rating is 2 A max. They were evaluated as Open type and
shall be installed within a enclosure.
Warning level
