H3RN-@-B
Safety Precautions
Precautions for Correct Use
• When using the H3RN-@-B in any place where the ambient
temperature is more than 50°C, supply 90% to 110% of the rated
voltages (at 12 VDC: 95% to 110%).
• Do not leave the H3RN-@-B in time-up condition (i.e., with the
internal relay in an ON state) for a long period of time (for example,
more than one month in any place where the ambient temperature
is high), otherwise the internal parts may become damaged.
Therefore, the use of the H3RN-@-B with a relay as shown in the
following circuit diagram is recommended.

G2R Relay
• In the case of the above circuit, the H3RN-@-B will be in pulse
operation. Therefore, if the circuit shown on page 3 is used, no
auxiliary relay will be required.
• Do not use the SPDT contact in a circuit which may cause shortcircuiting at three points (otherwise, short-circuiting of the power
supply may occur) because the SPDT contact of H3RN-1-B/-11-B
is composed of an SPST-NC contact.
3
: Auxiliary relay such as G2R Relay
• The H3RN must be disconnected from the socket when setting the
DIP switch, otherwise the user may touch a terminal imposed with
a high voltage and get an electric shock.
• Do not connect the H3RN-@-B as shown in the following circuit
diagram on the right hand side, otherwise the H3RN-@-B’s internal
contacts different from each other in polarity may become shortcircuited.
Correct
• Use the following safety circuit when building a self-holding circuit
with the H3RN-@-B and an auxiliary relay, such as a G2R Relay,
in combination.

• Do not set to the minimum setting in the flicker modes, otherwise
the contact may be damaged.
• Do not use the H3RN-@-B in places where there is excessive dust,
corrosive gas, or direct sunlight.
• Make sure that there is a space of 3 mm or more between any
H3RN-@-B Models next to each other. (When using the P2RF-08PU Socket, a space of 3 mm or more will be secured.) If a space of
3 mm or more is not secured, the ambient temperature must be
less than 50°C.
• The internal parts may become damaged if a supply voltage other
than the rated ones is imposed on the H3RN-@-B.
Precautions for EN 61812-1 Conformance
The H3RN-@-B as a built-in timer conforms to EN 61812-1 provided
that the following conditions are satisfied.
Handling
• Do not touch the DIP switch while power is supplied to the H3RN@-B.
• Before dismounting the H3RN-@-B from the socket, make sure
that no voltage is imposed on any terminal of the H3RN-@-B.
Wiring
• Basic insulation is ensured between the H3RN-@-B’s operating
circuit and control output.
Basic insulation: Overvoltage category III,
pollution degree 2
(with a clearance of 3.0 mm and a creepage
distance of 3.0 mm at 240 VAC)
• When using the P2RF-@-PU Socket, basic insulation is ensured in
the mounted condition for a voltage of 250 VAC max.

Recommended Replacement Periods and Periodic Replacement
as Preventive Maintenance
The recommended replacement period for preventive maintenance is
greatly influenced by the application environment of the product. As a
guideline for models that do not have a Maintenance Forecast
Monitor, the recommended replacement period is 7 to 10 years.* To
prevent failures that can be caused by using a product beyond its
service live, we recommend that you replace the product as early as
possible within the recommended replacement period. However,
realize that the recommended replacement period is for reference
only and does not guarantee the life of the product.
Many electronic components are used in the product and the product
depends on the correct operation of these components to achieve
product functions and performance. However, the influence of the
ambient temperature on aluminum electrolytic capacitors is large, and
the service life is reduced by half for each 10°C rise in temperature
(Arrhenius law). When the capacity reduction life of the electrolytic
capacitor is reached, the product may fail. We therefore recommend
that you replace the product periodically to minimize product failures
in advance.
* The following conditions apply: rated input voltage, load rate of 50%
max., ambient temperature of 35°C max., and the standalone
mounting method.
This product model is designed with a service life of 10 years
minimum under the above conditions.
