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 temperatureis high),otherwisetheinternal partsmay becomedamaged. Therefore, the use of the H3RN with a relay as shown in the following circuit diagram is recommended. 

**==> picture [30 x 14] intentionally omitted <==**

**----- Start of picture text -----**<br>
H3RN<br>G2R Relay<br>**----- End of picture text -----**<br>


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 ontherighthandside,otherwisetheH3RN’sinternalcontactsdifferent 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.

Donot usetheH3RNinplaces wherethereis excessive dust, corrosive gas, or direct sunlight. 

Makesurethat thereis aspace of 3 mm or morebetween any H3RN Models next to each other. (When using the P2RF-j-E Socket, a spaceof 3mm ormorewill besecured.)If aspaceof3mmormoreis 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 VDE Conformance** 

The H3RN as a built-in timer conforms to VDE 0435/P2021 provided that the following conditions are satisfied. 

## **Handling** 

Use the following safety circuit when building a self-holding circuit with the H3RN and an auxiliary relay, such as a G2R Relay, in combination. **r** s s } | X/a T/b @: H3RN G2R Relay tte 

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** 

Only a load with basic isolation can be connected to the output contact. TheH3RNis amodel withbasic isolation. Therefore, theH3RN and the load will ensure reinforced isolation, thus meeting VDE standards. 

Insulation requirement: Overvoltage category II, 

pollution degree 2 

(with a clearance of 1.5 mm and a creepage distance of 2.5 mm at 240 VAC) 

In the case of the above circuit, the H3RN will be in pulse operation. Therefore, if the circuit shown on page 9 is used, no auxiliary relay will be required.
