5 / 5 page NOTES 1. Coil operating power Pure DC current should be applied to the coil.The wave form should be rectangular. If it includes ripple, the ripple factor should be less than 5%. However, check it with the actual circuit since the characteristics may be slightly different. 2. Coil connection When connecting coils, refer to the wiring diagram to prevent mis-operation or malfunction. 3. Cleaning For automatic cleaning, the boiling method is recommended. Avoid ultrasonic cleaning which subjects the relays to high frequency vibrations, which may cause the contacts to stick. It is recommended that a fluorinated hydrocarbon or other alcoholic solvents be used. 4. Soldering We recommend the following soldering conditions 1) Automatic soldering 1) Preheating: 100°C 212°F, max. 60 s 2) Soldering: 250°C 482°F, max. 5 s 5. Others 1) If the relay has been dropped, the appearance and characteristics should always be checked before use. 2) The cycle lifetime is defined under the standard test condition specified in the JIS* C 5442-1986 standard (temperature 15 to 35°C 59 to 95°F, humidity 25 to 85%). Check this with the real device as it is affected by coil driving circuit, load type, activation frequency, activation phase,ambient conditions and other factors. Also, be especially careful of loads such as those listed below. (1) When used for AC load-operating and the operating phase is synchronous. Rocking and fusing can easily occur due to contact shifting. (2) High-frequency load-operating When high-frequency opening and closing of the relay is performed with a load that causes arcs at the contacts, nitrogen and oxygen in the air is fused by the arc energy and HNO3 is formed. This can corrode metal materials. Three countermeasures for these are listed here. 1. Incorporate an arc-extinguishing circuit. 2. Lower the operating frequency 3. Lower the ambient humidity 3) For secure operations, the voltage applied to the coil should be nominal voltage. In addition, please note that pick- up and drop-out voltage will vary according to the ambient temperature and operation conditions. 4) Heat, smoke, and even a fire may occur if the relay is used in conditions outside of the allowable ranges for the coil ratings, contact ratings, operating cycle lifetime, and other specifications. Therefore, do not use the relay if these ratings are exceeded. Also, make sure that the relay is wired correctly. 5) Incorrect wiring may cause unexpected events or the generation of heat or flames. 6) Check the ambient conditions when storing or transporting the relays and devices containing the relays. Freezing or condensation may occur in the relay, causing functional damage. Avoid subjecting the relays to heavy loads, or strong vibration and shocks. 6. Usage, transport and storage conditions 1) Ambient temperature, humidity, and atmospheric pressure during usage, transport, and storage of the relay: (1) Temperature: –40 to +70°C –40 to +158°F (2) Humidity: 5 to 85% RH (Avoid freezing and condensation.) The humidity range varies with the temperature. Use within the range indicated in the graph below. (3) Atmospheric pressure: 86 to 106 kPa Temperature and humidity range for usage, transport, and storage: 2) Condensation Condensation forms when there is a sudden change in temperature under high temperature and high humidity conditions. Condensation will cause deterioration of the relay insulation. 3) Freezing Condensation or other moisture may freeze on the relay when the temperatures is lower than 0°C 32°F. This causes problems such as sticking of movable parts or operational time lags. 4) Low temperature, low humidity environments The plastic becomes brittle if the relay is exposed to a low temperature, low humidity environment for long periods of time. Tolerance range (Avoid condensation when used at temperatures higher than 0 °C 32°F) (Avoid freezing when used at temperatures lower than 0 °C 32°F) 85 5 –40 –40 0 +32 +70 +158 Temperature, °C °F Humidity, %R.H. 2/19/2003 All Rights Reserved, © Copyright Matsushita Electric Works, Ltd.
