## **Connecting Sockets (Sold Separately)** 

## **H3Y/H3YN Series** 

Use one of the following Connecting Sockets: PYF @ A, PYF @ M, PY @ , PY @ -02, or PY @ QN(2)(-Y3). ( @ : 08 or 14) 

## **H3Y-** @ **-B/H3YN-** @ **-B Series** 

Use one of the following Connecting Sockets: PYF- @ -PU-L. ( @ : 08 or 14)

**H3Y Series** 

## **Accessories (Order Separately)** 

Use the PYF @ A, PY @ , PY @ -02, or PY @ QN(2) to mount the H3Y/H3YN. Use the PYF- @ -PU-L to mount the H3Y- @ -B/H3YN- @ -B. When ordering any one of these sockets, replace “ @ ” with “08” or “14.” 

## **Socket Mounting Plates (t = 1.6)** 

**(Excluding the H3Y-** @ **-B and H3YN-** @ **-B)** 

Use a Socket Mounting Plate to mount multiple Connecting Sockets in a row.

## **Relay Hold-down Clips** 

The Hold-down Clip makes it possible to mount the H3YN securely and prevent the H3YN from falling out due to vibration or shock. 

**Note:** When you attach the Hold-down Clip to or remove it from the Socket, take sufficient precautions to not injury your fingers, such as wearing gloves.

Gold-plated relays are used in the H3Y-4, H3YN-4, H3Y-4-B, specific symbol. H3YN-4-B, H3YN-4-Z, H3YN-41-Z, H3YN-4-Z-B, and H3YN-41-ZB Series. • Connect the power supply between terminals A1 (13) and A2 (14). Use to indicate prohibitions when there is a risk of For a DC power supply, connect the negative side to A1 (13) and minor injury from electrical shock or other source if the positive side to A2 (14). the product is disassembled. • The operating voltage will increase when using the H3Y/H3YN/ ~~(oe~~ H3Y-B/H3YN-B in any place where the ambient temperature is 

- The operating voltage will increase when using the H3Y/H3YN/ H3Y-B/H3YN-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%) when operating at 45 ° C or higher. 

Used for general mandatory action precautions for which there is no specified symbol. 

- Do not leave the H3Y/H3YN/H3Y-B/H3YN-B 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 (aluminum electrolytic capacitor) may become damaged. Therefore, the use of the H3Y/H3YN/H3Y-B/H3YN-B with a relay as shown in the following circuit diagram is recommended to extend the service life of the H3Y/H3YN/H3Y-B/ H3YN-B. 

## **CAUTION** 

Risk of fire and explosion due to arcing and relay heat generation that accompanies switching. Do not use in an environment where flammable or explosive gas is present. 

The service life of the output relay varies widely depending on switching capacity and switching conditions. Use only within the rated load and electrical life count, based on actual conditions of use. Risk of 1) contact sticking and burning if used past the service life. Always use a load current that does not exceed the rating, and if a heater is used, use a thermal switch in the load circuit. 

Auxiliary relay such as MY Relay 

- The H3YN/H3YN-B 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 remove the outer casing. 

- Do not connect the H3Y/H3YN/H3Y-B/H3YN-B as shown in the following circuit diagram on the right hand side, otherwise the H3Y's/H3YN's/H3Y-B's/H3YN-B's internal contacts different from each other in polarity may become short-circuited. 

In rare circumstances there is a risk of slight electrical shock, fire, or device damage. Do not disassemble, modify, repair, or otherwise touch the inside.

Tighten the screws for the lead wires to the Socket to the following torque. PYF Socket: 0.78 to 1.18 N·m 

- Use the following safety circuit when building a self-holding or selfresetting circuit with the H3Y/H3YN/H3Y-B/H3YN-B and an auxiliary relay, such as an MY Relay, in combination. 

This is the recommended range when crimp terminals are used. 

If the screws are not tightened sufficiently on Front-connecting Sockets, the lead wires may come off, connection failure may cause abnormal heating, or fires may occur. 

If they are tightened excessively, the screw threads may be damaged. 

: H3Y ®®: Auxiliary relay: MY Relay 

**36** 

**H3Y Series** 

- In the case of the above circuit, the H3YN will be in pulse operation. Therefore, if the circuit shown on page 13 is used, no auxiliary relay will be required. 

- Do not set to the minimum setting in the flicker modes, otherwise the contact may become damaged. 

- Be careful not to apply any voltage to the terminal screws on the back of the Timer. Mount the product so that the screws will not come in contact with the panel or metal parts. 

- Do not use the H3Y/H3YN/H3Y-B/H3YN-B in places where there is excessive dust, corrosive gas, or direct sunlight. 

- Do not mount more than one H3Y/H3YN/H3Y-B/H3YN-B closely together, otherwise the internal parts may become damaged. Make sure that there is a space of 5 mm or more between any H3Y/ H3YN/H3Y-B/H3YN-B Models next to each other to allow heat radiation. 

   - In order to conform to UL and CSA requirements when using the H3Y-4/-4-0/-4-B, H3YN-4/-41/-4-B/-41-B, or H3YN-4-Z/-41-Z/ -4-Z-B/-41-ZB, connect the Unit so that output contacts (contacts of different poles) have the same electric potential. 

   - In cases such as PLC input where the load is extremely small for the control output of a timer containing a power relay (using other than gold-plated contacts), reliability can be increased by using contacts of the same poles (e.g., the H3Y-2) in parallel. 

   - Always use the same type of wire. 

   - Installation There are no restrictions on the installation orientation. Install the Timer securely. 

- The internal parts may become damaged if a supply voltage other than the rated ones is imposed on the H3Y/H3YN/H3Y-B/H3YN-B. When more than 100 V is applied to 12 or 24 VDC models, the internal element (varistor) may break. 

## **Precautions for EN 61812-1 Conformance** 

The H3Y/H3YN/H3Y-B/H3YN-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 H3YN/ H3YN-B. 

- Before dismounting the H3YN/H3YN-B from the Socket, make sure that no voltage is imposed on any terminal of the H3YN/ H3YN-B. 

- The applicable Socket is the PYF@A (H3Y/H3YN) or PYF-@-PU-L (H3Y-B/H3YN-B). 

- Only basic insulation is ensured between the Y92H-3 Hold-down Clips and H3Y/H3YN/H3Y-B/H3YN-B internal circuits. 

- Do not allow the Y92H-3 Hold-down Clips to contact other parts. 

- The insulation test voltage between different pole contacts for the 4-pole model is the impulse voltage of 2.95 kV. 

## **Wiring** 

- The power supply for the H3Y/H3YN/H3Y-B/H3YN-B must be protected with equipment such as a breaker approved by VDE. 

- Basic insulation is ensured between the H3Y's/H3YN's/H3Y-B's/ H3YN-B's operating circuit and control output. 

• Insulation requirement: Overvoltage category II, pollution degree 1 (H3Y-4/-4-0/-4-B, H3YN-4/41/-4-B/-41-B, H3YN-4-Z/-41-Z/-4-Z-B/-41-Z-B), 

## **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. 

pollution degree 2 (H3Y-2/-2-0/-2-B, H3YN-2/21/-2-B/-21-B) (with a clearance of 1.5 mm and a creepage distance of 2.5 mm at 240 VAC) 

- Output terminals next to each other on the H3Y-4 or H3Y-4-0 must have the same polarity.
