1.Soldering must be completed within 10s at 260℃ or less or within 5s at 350℃ or less.
2.If poor ventilation is unavoidable,the load current must be reduced.
3.Make sure that the polarity is correct when connecting, to avoid damage to the relay.
4.Please do not use the relay beyond the descriptions in the data sheet.
5.If the output transient voltage exceeds the norminal value, a varistor should be connected to the SSR output terminal in parallel to prevent the relay being breakdown. The recommended varistor voltage as follows:
