Connections: For output terminals, the wire cross sections must be adapted to the load current and to the overcurrent protection device characteristics. The relay rated voltage must be adapted to the mains rated voltage. These relays use screw clamp connections. 2. Mounting: Only in vertical position. Protect heat-sensitive materials as well as people from contact with the heat sink. For non vertical mounting, the load current must be derated by 50% . The SSR requires air convection. Lack of air convection produces an abnormal heating. Keep a distance between the upper SSR and the lower SSR (see vertical 3.15 inches figure on the right). In case of zero position (80mm) space between two SSRs, reduce the load current. It’s suggested to maintain the heat sink temperature under 90°C. Forced cooling significantly improves the thermal performances. 3. Typical application loads: The DR relay may handle motor and resistive loads. For different loads, check the inrush current at turn-ON and possible overvoltages at turn-OFF or contact the factory. • Incandescent lamps — Inrush current is generally 10 times the current nominal for 10ms. • Electric discharge lamp — These loads often have overcurrent at turn-ON and overvoltage at turn-OFF. Use 480Vac SSR on 240Vac mains. • Transformer loads — Very high inrush current, up to 100 times the nominal current. • Capacitive loads — Very high current at turn-On and overvoltage at turn-Off. Use only zero-cross models. 4. Protection: To protect the SSR against a short-circuit 1~ of the load, use a fuse with a I2t value = 1/2 I2t value. Fuse 5. EMC: Immunity: lmmunity levels of the DR comply with EN61000-4-4 &5. L1 Emission: The system integrator must ensure that systems containing SSRs comply with the requirements of any rules and regulations applicable T1 at the system level. The very low zero-cross voltage + (<20V) improves the conducted emission level in Load – comparison with most SSRs with zero-cross voltage higher than 50V. N 6.
