## **Notes** 

## **Overtemperature protection** 

Optionally, the semiconductor relay has an overtemperature protection to monitor the temperature of the heat sink. To this end, a thermal release switch (NC contact) can be inserted into the respective pocket at the bottom of the semiconductor relay. As soon as the temperature of the heat sink exceeds for example 100°C, the thermal release switch. For thermal protection of the semiconductor relay, a thermal release switch of UCHIYA type UP62 – 100 can be installed.

## **Notes on Sizing for Selection of a Heat Sink** 

The heat generated by the load current must be dissipated by a suitable heat sink. It is imperative that the junction temperature of the semiconductor is maintained for all potential environmental temperatures of under 125°C. For this reason, it is important to keep the thermal resistance between the base plate of the semiconductor relay and the heat sink to a minimum. 

To protect the semiconductor relay effectively from excess heating, a thermally conducting paste should be applied before installation to the base plate of the heat sink between semiconductor relay and heat sink. 

From the tables below, select a suitable heat sink with the next lowest thermal resistance. Thus, it is ensured that the maximum junction temperature of 125°C is not exceeded. The load current in relation to the environmental temperature can be seen from the table.

## **Installation Instructions** 

## **Installation Instructions** 

## **General information** 

The service life and long-time reliability of a solid-state relay depends on its installation and use. Load type, load current, switching frequency, mains voltage and ambient temperature must be taken into account during the project design. To ensure the reliable operation of the devices, an exact analysis of the application and a calculation of the heat sink must be conducted in advance. Solid-state relays constantly produce heat during operation. The ambient conditions therefore require special attention. The choice of the correct heat sink is especially important since the constant overtemperature significantly reduces the service life of the devices. The use of a temperature switch is recommended if neither the load conditions nor the ambient temperatures are known. This switch is available as accessory and is inserted in a pocket on the bottom side. 

**==> picture [22 x 9] intentionally omitted <==**

**----- Start of picture text -----**<br>
Fig. 1<br>**----- End of picture text -----**<br>


**Attention:** The load output is not electrically separated from the mains even if no drive is present 

## **Overload protection (Fig. 1)** 

The solid-state relay must be protected against short circuit by a separate solid-state fuse of coordination type 2. Choosing the I2t value (switch-off integral) of the fuse half as large as the I2t value of the semiconductor is recommended. 

## **Overvoltage protection (Fig. 1)** 

Although the solid-state relays can withstand high peak voltages, it is better to switch an external varistor parallel to the load output. This is particularly recommended when switching inductive loads. The varistor voltage must be selected appropriate for the mains voltage. A wrong selection can create hazardous situations. As an option, the varistor is factory-installed.

Fig. 2<br>**----- End of picture text -----**<br>


## **Assembly on the heat sink (Fig. 2, Fig. 3)** 

A small amount of silicon-containing heat transfer compound is to be applied to the base plate to ensure a good thermal bond between solid-state relay and heat sink. As an alternative, a graphite foil can be placed between solid-state relay and heat sink. 

   - **Attention!** 

- J\ **Heat transfer compounds without silicon should not be used, since they may attack the plastic of the housing .** 

The solid-state relay is mounted to the heat sink using two M5x8 screws and matching washers. Both screws should be tightened in alternating fashion until a torque of 1 Nm is reached. After approx. one hour the screws need to be tightened further with a final torque of 2.5 Nm. This ensures that all excess heat transfer compound is squeezed out or that the graphite foil can well adapt to the contours of the surfaces.

## **Installation of the complete unit (Fig. 4)** 

The fins of the heat sink must be aligned in a manner allowing the unobstructed circulation of air. Without external fan, the fins must be aligned vertically to support natural convection.
