• Please make sure that the product specifications are the
same as you ordered.
• Please use the product in places where corrosive gases
(especially harmful gases, ammonia, etc.) and flammable
gases are not generated.
• Please use the product in places without liquids, oils,
chemicals, steam, dust, salt, iron, etc. (pollution degree 1 or 2).
• Please avoid places where large inductive interference,
static electricity,magnetic noise are generated.
• Please avoid places with heat accumulation caused by
direct sunlight, radiant heat, etc.
• When water enters, short circuit or fire may occur, so
please inspect the product carefully.
• Do not connect anything to the unused terminals.
• For DC types, please wire correctly, after checking the polarity
of the terminals.
• When disposing of the product, treat it as industrial waste.
• Pay attention to the edge of the heat sink, which may be sharp.
• The temperature of the main body and the heat sink may

▍ Installation interval
• As shown in the figure, set the installation interval to a distance
greater than the corresponding part size.
• Install the wiring duct at less than half the height of the heat
sink, so that it does not obstruct the flow of air.
• Since the SSR is satisfied under the ambient temperature of 25 ° C
or less, always use it in ambient temperatures lower than the
standard temperature.
[Unit : mm]
• When using 40A maximum load, use 10SQ wiring and use
clamping unit or lug when tightening.

▍ Installation method
• Be sure to install the SSR vertically.
• Inevitably, if installed horizontally, the performance of the
product will drop below 50 %.
Air out (FAN)
Wiring duct
• When installing the DIN rail, install it firmly because it is heavy.
Min.
10 mm
• Since the load output terminal width is 13 mm and the input
terminal width is 7 mm, tightly tighten using a terminal that is less
than that. (Load side bolt: M5, control terminal: M3)
