## 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. Use only within the specified ranges. Zenner diode If the power is switched on when the connections are insuffic ~~i~~ ent, there is a risk of abnormal heat ~~‘\~~ generation ~~.~~ Do not connect and use probes and @PCB Terminal Soldering sockets on individual relays ~~.~~ ¢ Solder at 290°C 290°C for 20 seconds 20 seconds seconds (max.) in soldering soldering bath ~~.~~ If the power is switched on whenthe connections ,» * It is not possible to wash wash relay as this as this this is not fully sealed sealed type generation ~~.~~ Please install and use relays under * To reduce the risk of specification deterioration, assemble are insuffic ~~i~~ ent, there is a risk of abnormal heat ~~A)~~ @Assembly recommended conditions. relays in a dust free, low humidity and non ~~-c~~ orrosive gas 

- ¢ Solder at 290°C 290°C for 20 seconds 20 seconds seconds (max.) in soldering soldering bath ~~.~~ * It is not possible to wash wash relay as this as this this is not fully sealed sealed type ~~.~~ * To reduce the risk of specification deterioration, assemble 

- @Assembly relays in a dust free, low humidity and non ~~-c~~ orrosive 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 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. 

- (Rates Voltage) — (Holing voltage) f ~~o er~~ 0.1 to 3 seconds

- @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 ~~.~~ 

- eElectrical Endurance ree ¢ 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. 

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