## Precautions
## @ Refer to PCB Relays Common Precautions for general precautions.
> ; ¢ Use diodes with reverse dielectric strength 10 times or more As that of coil rated voltage, and with forward current more than this relay is a high-voltage and high-current type, coil rated current. there is a risk of abnormal heat generation, smoke generation or fire if you use the relay with a contact biode voltage, current, or for a number of times beyond the Relay coil specified range.

- ¢ 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 220 g ~~.~~ Be careful of the strength of PCB. To reduce soldering crack due to heat stress, use
- ¢ @Drop K *Do not use relays that have been dropped as they may not A function properly.
- ®@Coil Voltage Reduction (holding voltage) after Relay 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 60%. Do not exceed the ranges due to the change of coil voltage change and so on.

- @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 ~~.~~
- * 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 ~~.~~

- * 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.
- ®Micro Load * Thismicro is loads a power such as relay signal switching. for high power switching. Do not use for
