replace "@" with "05" for SPDT or "08" for DPST-NO.
The P2RF-@cannot be used because the hook is a different shape.

Precautions
■Correct Use
When using the H3RN 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 in time-up condition 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 dam-
aged. Therefore, the use of the H3RN with a relay as shown in the
following circuit diagram is recommended.
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 as shown in the following circuit diagram
on the right hand side, otherwise the H3RN’s internal contacts differ-
ent from each other in polarity may become short-circuited.
Use the following safety circuit when building a self-holding circuit
with the H3RN and an auxiliary relay, such as a G2R Relay, in combi-
nation.
In the case of the above circuit, the H3RN will be in pulse operation.
Therefore, if the circuit shown on page 99 is used, no auxiliary relay
will be required.
Do not use the SPDT contact in a circuit which may cause short-cir-
cuiting at three points (otherwise, short-circuiting of the power supply
may occur) because the SPDT contact of H3RN-1/-11 is composed
of an SPST-NC contact.
Do not set to the minimum setting in the flicker modes, otherwise the
contact may be damaged.
Do not use the H3RN in places where there is excessive dust, corro-
sive gas, or direct sunlight.
Make sure that there is a space of 3 mm or more between any H3RN
Models next to each other. (When using the P2RF-@-E 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.
■Precautions for EN61812-1
Conformance
The H3RN as a built-in timer conforms to EN61812-1 provided that
the following conditions are satisfied.
Handling
Do not touch the DIP switch while power is supplied to the H3RN.
Before dismounting the H3RN from the socket, make sure that no
voltage is imposed on any terminal of the H3RN.
Wiring
Basic insulation is ensured between the H3RN’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)
The clearance from the edge of the P2R-087P Socket to internal,
current-carrying metal parts is 1.3 mm. Position the H3RN to provide
the necessary clearance for the voltage used.
When using the P2RF-@-E or P2R-057P Socket, basic insulation is
ensured in the mounted condition for a voltage of 250 VAC max.
