When wiring, pay attention to the polarity of the solid-state relay to prevent permanent damage from incorrect connections.The solid-state relay should be installed in a location with good heat dissipation, away from heat sources. If the ambient temperature is too high or heat dissipation is poor, increase the current margin to ensure even and efficient heat dissipation. When...
