General Notes

1. Relay must be mounted to proper sized beat sink hased on thermal curves. Thermal grease or a thermal pad must be used between relay and heat sink and be torqued down to 18-20/2.0-2.2in-lb/Nm.

2. When connection wiring to SSR, please ensure screws are torqued down properly (input 13-15/1.5-1.7in/lb/Nm, output13-15/1.5-1.7in-lb/Nm).

3. SSR's carrying load capacity is related to the operation ambient temperature and heat dissipation condition, please refer to the Thermal Derating Curve for derating.

4. The capacitive load will generate high inrush current at the moment when the SSR been turned on, which may damage the SSR. Therefore, if the load type is capacitive, or if the load has parallel capacitance, please make sure series connect a NTC in the load loop to suppress the inrush current to protect the SSR.
