Follow instructions in 'Cautions during Use'. Otherwise, it may cause unexpected accidents. 2., 24VAC signal input should be insulated and limited voltage/ or Class 2, SELV power supply device. 3. Install the unit in the well ventilated place. 3. Ground to the heat sink, panel, or DIN rail. Failure to follow this instruction may result in electric shock. 4. Ground to the panel. Failure to follow this instruction may result in electric shock. 5. While supplying power to the load or right after turning off the power of the load, do not touch the body and heat sink. Failure to follow this instruction may result in a burn due to the high temperature. 6. In order to protect the product from the short-circuit of the load, use rapid fuse of which I 2 t is under the 1/2 of SSR I 2 t. When short-circuited, replace the fuse to those of same specification with the used rapid fuse. 7. Install dummy resistance in parallel with the load, to keep the sum of flowing in the load and dummy resistance being over SSR minimum load. 8. When using random turn-on model for phase control, install noise filter between the load and the power of the load. 9.
