8 / 8 page H3Y H3Y 8 Installation Connection H3Y-2 H3Y-4 Connect the DC power supply to terminals 13 and 14 according to the polarity marks. Connect the DC power supply to terminals 13 and 14 according to the polarity marks. Precautions When selecting a control output, use the H3Y-2 for switching ON and OFF the power and the H3Y-4 for switching ON and OFF the minute load. The operating voltage will increase when using the H3Y 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 operat- ing at 50 °C or higher. Do not leave the H3Y 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 elec- trolytic capacitor) may become damaged. Therefore, the use of the H3Y with a relay as shown in the following circuit diagram is recom- mended to extend the service life of the H3Y. MY Relay H3Y Do not connect the H3Y as shown in the following circuit diagram on the right hand side, otherwise the H3Y’s internal contacts different from each other in polarity may become short-circuited. Correct Incorrect Use the following safety circuit when building a self-holding or self- resetting circuit with the H3Y and an auxiliary relay, such as an MY Relay, in combination. : H3Y Auxiliary relay: MY Relay Do not use the H3Y in places where there is excessive dust, corro- sive gas, or direct sunlight. Do not mount more than one H3Y closely together, otherwise the internal parts may become damaged. Make sure that there is a space of 5 mm or more between any H3Y Models next to each other to allow heat radiation. The internal parts may become damaged if a supply voltage other than the rated ones is imposed on the H3Y. When more than 100 V is applied to 12 or 24 VDC, the internal element (varistor) may break.
