(at 85°C 185°F) 9) The relay should not be installed near strong magnetic field (transformers, magnets, etc.) and should not be installed near objects that radiate heat. 10) If the several relays are mounted closely or a heat-generation object is close to the relay, take care to check the abnormal temperature-rise and the insulation distance between the terminals outside of the relay. 11) If you are using an inductive load (L load) such that L/R > 1ms, add surge protection in parallel with the inductive load. If this is not done, the electrical life will decrease and cut-off failure may occur. 12) In case using a capacitive load (Cload), please take a countermeasure as pre-charging to the capacitive load so that the inrush current will not surpass 40A. The relay might have a contact welding without such countermeasure. 13) This relay is a high-voltage directcurrent switch. In its final breakdown mode, it may lose the ability to provide the proper cut-off. Therefore, do not exceed the indicated switching capacity and life. (Please treat the relay as a product with limited life and replace it when necessary.) In the event that the relay loses cut-off ability, there is a possibility that burning may spread to surrounding parts, so configure the layout so that the power is turned off within one second and from the point of view of safety, consider installing a failsafe circuit in the device. 14) Please carry out the design which had a enough margin in conductor width and a space between conductors in the case of a design of a printed circuit board. 15) Contact terminals have polarity. So if the contact terminals were connected with opposite pole, the electric life would be shorter. There is no polarity if they are used for power distribution only. Please refer to "the latest product specifications" when designing your product. • Requests to customers : https://industrial.panasonic.com/ac/e/salespolicies/ Panasonic Corporation Electromechanical Control Business Division industrial.panasonic.com/ac/e/ 5 © Panasonic Corporation 2019 ASCTB326E 201903 GUIDELINES FOR POWER RELAYS AND HIGH-CAPACITY DC CUT OFF RELAYS USAGE For cautions for use, please read “GUIDELINES FOR RELAY USAGE”. https://industrial.panasonic.com/ac/e/control/relay/cautions_use/index.jsp Precautions for Coil Input Long term current carrying Maximum allowable voltage and temperature rise A circuit that will be carrying a current continuously for long periods without relay switching operation. (circuits for emergency lamps, alarm devices and error inspection that, for example, revert only during malfunction and output warnings with form B contacts) Continuous, long-term current to the coil will facilitate deterioration of coil insulation and characteristics due to heating of the coil itself. For circuits such as these, please use a magnetic-hold type latching relay. If you need to use a single stable relay, use a sealed type relay that is not easily affected by ambient conditions and make a failsafe circuit design that considers the possibility of contact failure or disconnection. Proper usage requires that the rated coil voltage be impressed on the coil. Note, however, that if a voltage greater than or equal to the maximum continuous voltage is impressed on the coil, the coil may burn or its layers short due to the temperature rise. Furthermore, do not exceed the usable ambient temperature range listed in the catalog. Operate voltage change due to coil temperature rise (Hot start) In DC relays, after continuous passage of current in the coil, if the current is turned OFF, then immediately turned ON again, due to the temperature rise in the coil, the pick-up voltage will become somewhat higher. Also, it will be the same as using it in a higher temperature atmosphere. The resistance/temperature relationship for copper wire is about 0.4% for 1°C, and with this ratio the coil resistance increases. That is, in order to operate of the relay, it is necessary that the voltage be higher than the pick-up voltage and the pick-up voltage rises in accordance with the increase in the resistance value. However, for some polarized relays, this rate of change is considerably smaller. DC Coil operating power Steady state 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, please check with the actual circuit since the electrical characteristics may vary. The rated coil voltage should be applied to the coil and the set/reset pulse time of latching type relay differs for each relays, please refer to the relay's individual specifications. Coil connection When connecting coils of polarized relays, please check coil polarity (+,-) at the internal connection diagram (Schematic). If any wrong connection is made, it may cause unexpected malfunction, like abnormal heat, fire and so on, and circuit do not work. Avoid impressing voltages to the set coil and reset coil at the same time. Ambient Environment Dew condensation Usage, Transport, and Storage Conditions Condensation occurs when the ambient temperature drops suddenly from a high temperature and humidity, or the relay is suddenly transferred from a low ambient temperature to a high temperature and humidity. Condensation causes the failures like insulation deterioration, wire disconnection and rust etc. Panasonic Corporation does not guarantee the failures caused by condensation. The heat conduction by the equipment may accelerate the cooling of device itself, and the condensation may occur. Please conduct product evaluations in the worst condition of the actual usage. (Special attention should be paid when high temperature heating parts are close to the device. Also please consider the condensation may occur inside of the device.) During usage, storage, or transportation, avoid locations subjected to direct sunlight and maintain normal temperature, humidity and pressure conditions. Temperature/Humidity/Pressure When transporting or storing relays while they are tube packaged, there are cases the temperature may differ from the allowable range. In this case be sure to check the individual specifications. Also allowable humidity level is influenced by temperature, please check charts shown below and use relays within mentioned conditions. (Allowable temperature values differ for each relays, please refer to the relay's individual specifications.) Icing Condensation or other moisture may freeze on relays when the temperature become lower than 0°C.This icing causes the sticking of movable portion, the operation delay and the contact conduction failure etc. Panasonic Corporation does not guarantee the failures caused by the icing. The heat conduction by the equipment may accelerate the cooling of relay itself and the icing may occur. Please conduct product evaluations in the worst condition of the actual usage. Low temperature and low humidity The plastic becomes brittle if the switch is exposed to a low temperature, low humidity environment for long periods of time. High temperature and high humidity Storage for extended periods of time (including transportation periods) at high temperature or high humidity levels or in atmospheres with organic gases or sulfide gases may cause a sulfide film or oxide film to form on the surfaces of the contacts and/or it may interfere with the functions. Check out the atmosphere in which the units are to be stored and transported. 1) Temperature: The tolerance temperature range differs for each relays, please refer to the relay’s individual specifications 2) Humidity: 5 to 85 % RH 3) Pressure: 86 to 106 kPa Humidity, %R.H. 85 Allowable range (Avoid icing when used at temperatures lower than 0° C) 5 –40 (Avoid condensation when used at temperatures higher than 0° C) 0 Ambient temperature, ° C 85 Panasonic Corporation Electromechanical Control Business Division industrial.panasonic.com/ac/e/ -1- c Panasonic Corporation 2019 ASCTB412E 201903 GUIDELINES FOR POWER RELAYS AND HIGH-CAPACITY DC CUT OFF RELAYS USAGE Package In terms of the packing format used, make every effort to keep the effects of moisture, organic gases and sulfide gases to the absolute minimum. Silicon When a source of silicone substances (silicone rubber, silicone oil, silicone coating materials and silicone filling materials etc.) is used around the relay, the silicone gas (low molecular siloxane etc.) may be produced. This silicone gas may penetrate into the inside of the relay. When the relay is kept and used in this condition, silicone compound may adhere to the relay contacts which may cause the contact failure. Do not use any sources of silicone gas around the relay (Including plastic seal types). NOx Generation When relay is used in an atmosphere high in humidity to switch a load which easily produces an arc, the NOx created by the arc and the water absorbed from outside the relay combine to produce nitric acid. This corrodes the internal metal parts and adversely affects operation. Avoid use at an ambient humidity of 85%RH or higher (at 20°C). If use at high humidity is unavoidable, please contact our sales representative. Others Cleaning 1) Although the environmentally sealed type relay (plastic sealed type, etc.) can be cleaned, avoid immersing the relay into cold liquid (such as cleaning solvent) immediately after soldering. Doing so may deteriorate the sealing performance. 2) Cleaning with the boiling method is recommended(The temperature of cleaning liquid should be 40°C or lower ). Avoid ultrasonic cleaning on relays. Use of ultrasonic cleaning may cause breaks in the coil or slight sticking of the contacts due to ultrasonic energy.
