Improper handling may cause damage to the product and its peripherals.
Warning
1. Risk of Electrocution
●Always disconnect the product from the main power source before doing any wiring work.
●Make sure that the cover is attached while the product is energized.
●Do not open the case whether or not the product is energized.
●Do not touch the product while it is energized.
●Do not touch the terminal right after the power switch is turned OFF even if the product is not energized. (There is a
risk of electrocution by the charged electricity in the condenser.)
2. Risk of Fire and Burn
●Do not touch the radiation fin while the product is energized or right after the power switch is turned OFF.
●Do not use the product in a place that is exposed to flammable and explosive gases.
●Do not leave combustible items near the place where the product is installed.
●Take necessary safety measures, such as external fuse and breaker, against overcurrent, short circuit, and
breakdown.
●Make sure to properly attach the wire to the terminal by fastening them with the designated torque. (Failure to do so
may cause abnormal heating of the terminal.)
3. Others
●Do not use this product for purposes beyond the scope of its specification.
●Be careful not to drop the product on your body.
Caution
●Do not soak the product in water, cleaning solvent, chemical solution, and such other similar liquids.
●Do not insert metal pieces and conductive materials into the product.
●Do not disassemble or alter the product.
●Select the electric wire with appropriate thickness according to the flowing current.
●Do not drop the product. Do not apply abnormal vibration or impact to the product.
●Use a power supply within the rated frequency range.

Important Reminder Regarding Export Trade Control
Order
Please investigate the client and purpose of usage to make
sure that the product will not be used as a weapon of mass
destruction (e.g., for military purposes and military facilities).
Be extra careful with reselling to prevent the product from
being exported illegally.
Proper Ways of Usage
1. Dimensions and Mounting
（1）Dimensional Outline Drawing
（2）Panel Machining Diagram
（3）Tightening Torque for the Panel
Mount the panel with a tightening torque of 1.18 to
1.47N・m.
（4）Installation
・Vertical Installation
・Horizontal Installation
・
* Use the product within 70% of the rated load
current.
3. Wiring and Connection
(1) Sample Connection with Temperature Controller
(2) Sample Connection with External Volume
(Manual Setting)
* Volume shall be provided by the customer.
* The product cannot be used as an inclination
setting unit in combination with the temperature
controller.
①：Input Terminal (1)
②：Input Terminal (2)
③：Volume Terminal (3)
④：Volume Terminal (4)
⑤：Output Terminal (T1)
⑥：Output Terminal (T2）
⑦：Power Terminal (T3)
The input impedance of the product is 250Ω. ③ 5V is
outputted from the volume terminal. Therefore, the input
voltage of the product shall be 5V × (250Ω ÷ (External
Resistance Value + 250Ω)). Select the value of the
resistance of an external volume according to the required
amount of power for the adjustment.
The figure of the sample connection shows the usage of 2kΩ
external volume, which allows the adjustment of input
voltage between 1VDC and 5VDC with an external volume.
(3) Wiring of Input
a) Size of Electric Wire
・Single Wire
:
0.14 to 0.5mm2
・Twisted Wire
:

b) Tip Treatment
c) How to Insert
Insert the electric wire after pushing the
connector lever inside as shown in the figure
above. Pushing the electric wire inside with
force without pushing the lever may lead to
contact failure or disconnection.

4. Precaution from the Viewpoint of the Design of
Electrical Circuit
（1）Protection Circuit of the Output Side
a) This product is composed of
semiconductors and may break down by
surge voltage and current. Upon such,
most of its mode of breakdown is “short
mode (breakdown by a short circuit)”
where control is no longer possible under
the condition of which the load is turned
ON. Therefore, in case of a product
abnormality, the failsafe circuit must be
designed in such a way that it disconnects
the load circuit not by the product itself but
by a safety device, such as a breaker and
a contactor.
b) In case a short-circuit current or
overcurrent is flown into the output side of
the product, it will destroy the built-in
output element.
Please add the quick-blow fuse within the
range below to the load circuit.
Isurge > Iff > Ir
Isurge
:
One-cycle Surge ON
Current of the Product
Iff
:
Fusing Current of Quick-
blow Fuse
Ir
:
Rush Current of Load
（2）Precaution on the Type of Load
a) In the case of a small current load and
sensitive load, leakage current during
OFF may prevent the product from turning
itself OFF. In such a case, reduce the
leakage current during OFF that flows into
the load by connecting the shunt
resistance (Rp) in parallel to the load.
Shunt resistance (Rp) can be calculated
by the formula below.
Shunt Resistance (Rp) < IR × RL / ILEK –
IR
IR: Load OFF Current
ILEK: Leakage Current at Open Circuit
b) This product is designed to control the
resistance load. In case of a load with high
inductance, such as transformer, make
sure to verify the normality of the
operation with the actual device to avoid
malfunction during the commutation due
to the delay of the current phase against
the voltage.
（3）Explanation of the Movement
a) This product controls the output, which is
proportional to input (4 to 20mADC), by
the cycle control mode. It can also be
connected to the external volume, which
allows the user to use the product without
the analog input.
b) “Soft Up” and “Soft Down” are functions
that limit the sudden change of the output
power by changing the output gradually
whenever the input setting changes.
（4）Others
This product is not designed for a series connection
to improve voltage endurance and for parallel
connection to increase electric capacity.
