Use the P2RF-@-E or P2R-@7P to mount the H3RN. When ordering any one of these sockets, replace "@" with "05" for SPDT or "08" for DPST-NO. The P2RF-@ cannot be used because the hook is a different shape.

**H3RN** 

## **Safet Precautions y** 

## ■ **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 diagram is recommended.

X : 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 as shown in the following circuit diagram on the right hand side, otherwise the H3RN’s internal contacts different from each other in polarity may become short-circuited.

Do not use the SPDT contact in a circuit which may cause short-circuiting 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, corrosive 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.

G2R Relay<br>**----- End of picture text -----**<br>


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. 

Overvoltage category III, pollution degree 2 (with a clearance of 3.0 mm and a creepage distance of 3.0 mm at 240 VAC) 

Basic insulation: 

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.
