1. Please pay more attention to actual load current and ambient temperature for module selection. When the SSR is used for full load operation, we must install an adequate heatsink or take other effective cooling measures. When the ambient temperature is high, please refer to the curve of Max. Load Current vs Ambient Temperature for derating.
2.Apply heat-conducting silicon grease or a thermal transfer pad on the space between SSR and heat sink. Then, screw the heatsink firmly. In that case, it would keep the SSR from damaging by overheat.
3.Tighten the SSR terminal screws properly. If the screws are loose, the SSR will be damaged by heat generated from connections. Also, excessive screw mounting torque may damage relay internal components. We recommended screw installation torque as follows :M3 screw mounting torque of (0.58~0.98)N.m.
4. Please do not use the relay beyond the descriptions in the data sheet.
