H3RN

Safety 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 (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 with a relay as shown in the following circuit dia-

gram 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 3 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.
