1.Soldering must be completed within 10s at 260 or less or within 5s at 350 or less.

2.The SSR case serves to dissipate heat. Install the relays so that they are adequately ventilated. If poor ventilation is unavoidable,the load current must be reduced. Please refer to the curve of "Max. Load current Vs. Ambient Temperature".

3.The input circuitry does not incorporate a circuit protecting the SSR from being damaged due to a reversed connection. Make sure that the polarity and the input and output are correct when connecting. 

4.If the output transient voltage exceeds the norminal value, a varistor should be mounted on the SSR output terminal in parallel to prevent the relay being breakdown. The recommended varistor voltage 470V.

5.When using the relay in phase control applications, at a phasecontrol angle close to 180 degrees the relay's input signal turn off at the trailing edge of the AC sine wave must be limited to end 200μs before AC zero cross. This  assures that the relay has time to switch off. Shorter times may cause loss of control at the following half cycle. 

6.Please do not use the relay beyond the descriptions in the datasheet.
