Tighten the screws on the terminal block and the connector lock-
ing screws securely using a tightening torque within the following
ranges. Loose screws may occasionally cause fire, resulting in
minor or moderate injury, or damage to the equipment.
Terminal block screws: 0.40 to 0.56 N·m
Perform correct setting of the product according to the application.
Failure to do so may occasionally cause unexpected operation,
resulting in minor or moderate injury, or damage to the equipment.
Ensure safety in the event of product failure by taking safety mea-
sures, such as installing a separate overheating prevention alarm
system. Product failure may occasionally prevent control, or oper-
ation of alarm outputs, resulting in damage to the connected facil-
ities and equipment.
Do not use the equipment for measurements within Measurement
Categories II, III, or IV (according to IEC61010-1). Doing so may
occasionally cause unexpected operation, resulting in minor or
moderate injury, or damage to the equipment. Use the equipment
for measurements only within the Measurement Category for
which the product is designed.
The service life of the output relays depends on the switching
capacity and switching conditions. Consider the actual application
conditions and use the product within the rated load and electrical
service life. Using the product beyond its service life may occa-
sionally result in contact welding or burning.

VI
(1) Use and store the product within the specified ambient temperature and
humidity ranges. If several products are mounted side-by-side or arranged in a
vertical line, the heat dissipation will cause the internal temperature of the
products to rise, shortening the service life. If necessary, cool the products
using a fan or other cooling method.
(2)
Provide sufficient space around the product for heat dissipation. Do not block the
vents on the product.
(3) Use the product within the noted supply voltage and rated load.
(4) Be sure to confirm the name and polarity for each terminal before wiring the
terminal block and connectors.
(5) Do not connect anything to unused terminals.
(6) Use the specified size of crimp terminals (M3, width: 5.8 mm max.) for wiring
the terminal block.
(7) To connect bare wires to the terminal block, use AWG22 to AWG14 (cross-
sectional area: 0.326 to 2.081 mm2) to wire the power supply terminals and
AWG28 to AWG16 (cross-sectional area: 0.081 to 1.309 mm2) for other
terminals. (Length of exposed wire: 6 to 8 mm)
(8) Ensure that the rated voltage is achieved no longer than 2 s after turning the
power ON.
(9) Turn OFF the power first before drawing out the product. Never touch the
terminals or the electronic components, or subject them to physical shock.
When inserting the product, do not allow the electronic components to contact
the case.
(10) Do not remove the inner circuit board.
(11) Output turns OFF when shifting to the initial setting level in certain modes.
Take this into consideration when setting up the control system.
(12) Allow the product to warm up for at least 30 minutes after the power is turned
ON.
(13) Install surge absorbers or noise filters in devices near the product that generate
noise (in particular, devices with an inductance component, such as motors,
transformers, solenoids, and magnetic coils). If a noise filter is used for the
power supply, check the voltage and current, and install the noise filter as close
as possible to the product. Separate the product as far as possible from
devices generating strong high-frequency noise (e.g., high-frequency welders
and high-frequency sewing machines) or surges.
Do not tie noise filter input/output wires together.
(14) Keep the wiring for the product's terminal block and connector separate from
high-voltage, high-current power lines to prevent inductive noise. Do not run the
wiring parallel to or in the same cable as power lines. The influence of noise
can also be reduced by using separate wiring ducts or shield lines.
(15) Install an external switch or circuit breaker and label them clearly so that the
operator can quickly turn OFF the power.
(16) Do not use the product in the following locations:
· Locations where dust or corrosive gases (in particular, sulfuric or ammonia
gas) are present.
· Locations where icing or condensation may occur.
· Locations exposed to direct sunlight.
· Locations subject to excessive shock or vibration.
· Locations where the product may come into contact with water or oil.
· Locations subject to direct radiant heat from heating equipment.
· Locations subject to extreme temperature changes.
(17) Cleaning: Do not use thinners. Use commercially available alcohol.
Precautions for Safe Use

VII
●Service Life
Use the product within the following temperature and humidity ranges:
Temperature: −10 to 55°C (no icing or condensation)
Humidity: 25% to 85%
When the product is installed inside a control panel, make sure that the temperature
around the product, not the temperature around the control panel, does not exceed
55°C.
The service life of this product and similar electronic devices is determined not only
by the number of switching operations of relays but also by the service life of
internal electronic components. Component service life is affected by the ambient
temperature: the higher the temperature becomes, the shorter the service life
becomes and, the lower the temperature becomes, the longer the service life
becomes. Therefore, the service life can be extended by lowering the temperature
of the product.
Be sure to install the product according to the specified conditions. Otherwise, the
heat generated by the product will cause the internal temperature to rise, short-
ening the service life. If necessary, cool the product using fans or other means of air
ventilation.
When providing forced cooling, however, be careful not to cool down the terminals
sections alone to avoid measurement errors.
●Noise Countermeasures
To prevent inductive noise, separate the wiring for the product's terminal block and
connector from high-voltage, high-current power lines. Do not run the wiring parallel
to or in the same cable as power lines. The influence of noise can also be reduced
by using separate wiring ducts or shield lines.
Install surge absorbers or noise filters in devices near the product that generate
noise (in particular, devices with an inductance component, such as motors, trans-
formers, solenoids, and magnetic coils).
If a noise filter is used for the power supply, check the voltage and current, and
install the noise filter as close as possible to the product.
Separate the product as far as possible from devices generating strong high-
frequency noise (e.g., high-frequency welders and high-frequency sewing
machines) or surges.
●Measurement Accuracy
When extending the thermocouple lead wire, be sure to use a compensating wire
that matches the thermocouple type.
When extending the lead wire of the platinum resistance thermometer, be sure to
use wires that have low resistance, and make sure that the resistances of the three
lead wires are the same.
If the measurement accuracy is low, check whether the input shift is set correctly.
●Waterproofing
The degree of protection is as shown below.
