• Be sure to install the SSR vertically.
• Inevitably, if installed horizontally, the performance of the
product will drop below 50 %.
• 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.
• When using 40A maximum load, use 10SQ wiring and use
clamping unit or lug when tightening.
• When installing the DIN rail, install it firmly because it is heavy.
• 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)

INSTRUCTION MANUAL
▍Safety information
DANGER
Indicates an imminently hazardous situation which, if not avoided, will result in death or serious injury
WARNING
Indicates a potentially hazardous situation which, if not avoided, could result in death or serious injury
CAUTION
Indicates a potentially hazardous situation which, if not avoided, may result in minor injury or property damage
Please read the safety information carefully before the use, and use the product correctly.
The alerts declared in the manual are classified into
Danger, Warning
and
Caution
according to their importance
• The input/output terminals are subject to electric shock
risk. Never let the input/output terminals come in contact
with your body or conductive substances.
DANGER
• 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
become extremely high when electric power is applied,
which may cause burns.
• In case of product malfunction, remove only the main body.
• Because the SSR heats up when power is on, the lower the
heat sink and ambient temperatures, the longer the life.
• Please read the safety information carefully before the use,
and use the product correctly.
• If there is a possibility that a malfunction or abnormality of
this product may lead to a serious accident, install an
appropriate protection circuit on the outside and plan to
prevent accidents.
• Please supply the rated power voltage, in order to prevent
product breakdowns or malfunctions.
• To prevent electric shocks and malfunctions, do not supply
power until the wiring is completed.
• Please disassemble the product after turning OFF the power.
• Any use of the product other than those specified by the
manufacturer may result in personal injury or property
damage.
• Please use this product after installing it to a panel,
because there is a risk of electric shock.
WARNING
CAUTION
• If the heat sink temperature is lower than the set
temperature the alarm is automatically released.
