Condensation will cause deterioration of the relay insulation. 5) 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. 6) 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.

Solder and cleaning conditions 1) Please obey the following conditions when soldering automatically. (1) Preheating: Within 120°C 248°F (solder surface terminal portion) and within 120 seconds (2) Soldering iron: 260°C±5°C 500°F±41°F (solder temperature) and within 6 seconds (soldering time) 2) Since this is not a sealed type relay, do not clean it as is. Also, be careful not to allow flux to overflow above the PC board or enter the inside of the relay. –5– © Panasonic Corporation 2013 ASCTB196E-1 201307-T LF-G (ALFG)

Cautions for use 1) For precautions regarding use and explanations of technical terminology, please refer to our web site. (http://industrial.panasonic.com/ac/e/) 2) To ensure good operation, please keep the voltage on the coil ends to ±5% (at 20°C 68°F) of the rated coil operation voltage. Also, please be aware that the pick-up voltage and drop-out voltage may change depending on the temperature and conditions of use. 3) Keep the ripple rate of the nominal coil voltage below 5%. 4) Please test with actual device when using the coil holding voltage with PWM control. 5) The cycle lifetime is defined under the standard test condition specified in the JIS C5442 standard (temperature 15 to 35°C 59 to 95°F, humidity 25 to 75%). 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) Highly frequent load-operating When highly frequent 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. • Incorporate an arc-extinguishing circuit. • Lower the operating frequency • Lower the ambient humidity 6) This value can change due to the switching frequency, environmental conditions, and desired reliability level, therefore it is recommended to check this with the actual load. Please contact .......... 7) 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. 8) If the relay has been dropped, the appearance and characteristics should always be checked before use. 9) Incorrect wiring may cause unexpected events or the generation of heat or flames. 10) If complying with the Electrical Appliance and Material Safety Law (300V AC), please use with a nominal current no higher than 10A. 11) In order to reduce the occurrence of solder cracking due to thermal stress on the PC board, please use a double-face through hole PC board.
