Note : Varistor surge protection device should be connect parallel to coil(s). Suitable voltage of varistor is times the coil voltage. Note : For max. contact life and correct functioning of the relay, positive polarity of load should be connected to pin 8 and pin 5. If not, damage to the relay can occur.! Warning: At current loads at max. switching capacity 0A (00VDC) correct polarity is vital for the correct and safe functioning of the relay
WARNING! We highly recommend to use the layouts on this datasheet to switch 0A 50VDC or 0A 00VDC. Polarity of the terminals shall be kept as specified, otherwise fire or electric shock may occur. There would be a possibility that high voltage DC relay loses breaking current ability as one of failure modes. Please provide fail safeness design on the not to result in any injury or deaths or damages. To secure safety, the relay shall not be used in exceeding its specifications including operation life, and handle the relay as a periodic maintenance component. Caution! Each coil shall be synchronized completely in case coils are used separately at 0A 50VDC switching. Incomplete synchronization may shorten relay life excessively.! Magnetic field is generated on the top surface of relay. Please consider its influence to other components. When or more relays are mounted quite closely, please confirm operation before actual use.! All values mentioned in this datasheet are provided under ideal conditions. Please perform the confirmation test before actual use.! Reflow soldering is prohibited! Do not use FTR-J relays for automotive applications.! Do not use relays in the atmosphere with sulfide gas, chloride gas or nitric oxide. Contact resistance may increase.! Do not use silicon or silicon-containing product or materials near relays. It may cause contact failure. 8
