## Safety Precautions 

Turn off the power to the relay before starting installation, removal, wiring, maintenance, and inspection of the relays. Failure to turn power off may cause electrical shock or fire hazard.

Observe specifications and rated values, otherwise electri cal shock or fire hazard may be caused. 

Use wires of the proper size to meet the voltage and cur rent

## Instructions 

## Driving Circuit for Relays 

1. To make sure of correct relay operation, apply rated volt age to the relay coil. 

2. Input voltage for the DC coil: 

- A complete DC voltage is best for the coil power to make sure of stable relay operation. When using a power supply containing a ripple voltage, suppress the ripple factor within 5%. When power is supplied through a rectification circuit, the relay operating characteristics, such as pickup voltage and dropout voltage, depend on the ripple factor. Connect a smoothing capacitor for better operating char acteristics as shown below.

3. Operating the relay in synchronism with AC load: If the relay operates in synchronism with the AC power voltage of the load, the relay life may be reduced. If this is the case, select a relay in consideration of the required reliability for the load. Or, make the relay turn on and off irrespective of the AC power phase or near the point where the AC phase crosses zero voltage.

## 4. Leakage current while relay is off: 

- When driving an element at the same time as the relay operation, a special consideration is needed for the circuit design. As shown in the incorrect circuit below, Leakage current (Io) flows through the relay coil while the relay is off. Leakage current causes the coil release failure or adversely affects the vibration resistance and shock resis tance. Design a circuit as shown in the correct example.

Incorrect Correct<br>R TE R<br>Io<br>**----- End of picture text -----**<br>


5. Surge suppression for transistor driving circuits: 

- When the relay coil is turned off, a high-voltage pulse is generated, causing the transistor to deteriorate and sometimes to break. Be sure to connect a diode to sup press the counter electromotive force. Then, the coil release time becomes slightly longer. To shorten the coil release time, connect a Zener diode between the collector and emitter of the transistor. Select a Zener diode with a Zener voltage slightly higher than the power voltage.

## Instructions 

## Protection for Relay Contacts 

1. The contact ratings show maximum values. Make sure that these values are not exceeded. When an inrush cur rent flows through the load, the contact may become welded. If this is the case, connect a contact protection circuit, such as a current limiting resistor. 2. Contact protection circuit: 

When switching an inductive load, arcing causes carbides to form on the contacts, resulting in an increased contact resistance. In consideration of contact reliability, contact life, and noise

suppression, use of a surge absorbing cir cuit is recommended. Note that the release time of the load becomes slightly longer. Check the operation using the actual load. Incorrect use of a contact protection cir cuit will adversely affect switching characteristics. Four typical examples of contact protection circuits are shown in the following table:

## Other Precautions 

1. General notice: 

- •To maintain the initial characteristics, do not drop the relay or shock the relay. 

- •The relay cover cannot be removed from the base during normal operation. To maintain the initial characteristics, do not remove the relay cover. 

- •Use the relay in environments free from condensation of dust, sulfur dioxide (SO2), and hydrogen sulfide (H2S). 

- •Make sure that the coil voltage does not exceed the appli cable coil voltage range. 

2. Connecting outputs to electronic circuits: 

- When the output is connected to a load which responds very quickly, such as an electronic circuit, contact bounc ing causes incorrect operation of the load. Take the follow ing measures into consideration. a) Connect an integral circuit. 

- b) Suppress the pulse voltage due to bouncing within the noise margin of the load. 

3. UL- and CSA-approved ratings may differ from product rated values determined by IDEC. 

4. Do not use relays in the vicinity of strong magnetic field as this may affect relay operation. 

- •DC diode type has polarity. 

- •The surge absorbing element on AC relays with RC or DC relays with diode is provided to absorb the counter electro motive force generated by the coil. When the relay is sub ject to an excessive external surge voltage, the surge absorbing element may be damaged. Add another surge absorbing provision to the relay to prevent damage.

Generally, switching a DC inductive load is more difficult than switching a DC resistive load. Using an appropriate arc suppressor, however, will improve the switching char acteristics of a DC inductive load.
