## **Precautions** 

- **Please refer to "PCB Relays Common Precautions" for correct use.** Correct Use 

- ~~——_—=—ss—=its~~ 

##  **Mounting Direction** 

- The relay is limited for mounting direction due to the specification of operation voltage and electrical durability. Do not use in any other direction except as indicated in below chart. There is a risk of reduced operational lifetime for failure to observe this warning.

- G 7  **Coil Voltage Reduction (Holding Voltage) after Relay** E B **Operation** • Use this relay with coil voltage reduction. 

   - Apply the rated voltage for 0.1 to 3 seconds to the coil first. 

   - The range of coil rated voltage must be set as 100 to 120%, and holding voltage must be 45 to 65%. Do not exceed the ranges due to the change of coil voltage change and so on. 

100 to 120% (Rated voltage) 45 to 65% (Holding voltage)

0.1 to 3 seconds<br>**----- End of picture text -----**<br>


- Applied coil Coil voltage resistance * Coil power consumption 

- Rated voltage 100 to 120% 51 Ω (12 VDC) Approx. 2.8 to 4.0 mW 

- Holding voltage 45 to 65% 206 Ω (24 VDC) Approx. 0.57 to 1.2 mW 

- ~~——~~ * The coil resistances were measured at a coil temperature of 23°C with tolerances of ± 10%. 

##  **Diode Connection for Operating Coil** 

- Connect diode or Zener diode (or Varistor) to the coil (refer to the picture below). 

- Diode is for coil surge absorption. Ensure to include Zener diode as there is a possibility of any influence for switching capability when only using diodes. 

##  **PCB Terminal soldering** 

- Solder at 290°C for 20 seconds (max.) in soldering bath. 

- It is not possible to wash relay as this is not fully sealed type. 

##  **Assembly** 

- To reduce the risk of specification deterioration, assemble relays in a dust free, low humidity and non-corrosive gas environment. 

- Take care when mounting relays to utilize adequate anchorage on both sides of PCB to optimize heat transfer and reduce risk for both heat and mechanical stress. 

- This product weight is about 100 g. Be careful of the strength of PCB. To reduce soldering crack due to heat stress, use both sides through hole PCB. 

##  **Drop** 

- Do not use relays in the event of any droppage. 

##  **Electrical Endurance** 

- As this relay is high voltage and high current type, there are increased risks of abnormal heat or smoke generation if you use in an application inconsistent with published specification. Use only within specified rating. 

- This relay's electrical endurance specification is based on our company's standard test procedure with resistive loads. Relays intended for use with remove; types of drive circuits PWM, capacitive, resistive dropper etc.), types of loads (e.g. capacitive or inductive), and switching cycles (duty and operation timing) must be tested to confirm suitability to the actual intended application. 

- The final failure mode is failure to break the circuit. In such a case, burning may extend to surrounding components. Implement safety circuits and other measures to minimize the risk of mechanical failure. 

- Do not apply high current to this relay using copper probe or socket while pressure contact of terminals is insufficient. There is a risk of abnormal heat generation. 

- Properly implement this relay onto a PCB before use. If not implemented securely, there is a risk of abnormal heat generation when high current is applied. 

##  **Micro load** 

   - This is a power relay for high power switching. Do not use for micro loads such as signal switching. 

- Coil has no polarity. Connect the diodes in the reverse polarity of the voltage applied to the coil. 

- The recommended Zener diode voltage is 3 times that of the rated coil voltage. 

- Use diodes with reverse dielectric strength 10 times or more that of coil rated voltage, and with forward current more than coil rated current.
