Temperature Precautions: Do not touch the main body or the heat sink immediately during the power-on process or after the power is cut off to avoid burns. Electric shock risk: Do not touch the load terminals immediately after the power is cut off. The built-in buffer circuit may be electrified. When using an SSR with a terminal cover, please ensure that the terminal cover is installed. Wiring operations must be carried out with the power supply cut off. Load current: Short-circuit current should be avoided flowing through the SSR load; otherwise, it may cause the SSR to rupture. Voltage and current: Do not apply voltage or current exceeding the rated value to each terminal of the SSR to avoid SSR failure or burnout. Terminal screws: Ensure that the terminal screws are tightened. Loosening may cause abnormal heating and burnout. Heat dissipation: Do not impede the air convection around the main body and the heat sink to avoid abnormal heating, which may cause short circuit faults or burnout of the output components. Wiring and screw tightening: Please follow the "Precautions for Use" to wire and tighten the screws correctly to avoid abnormal heating and burning due to incomplete tightening of the wiring or screws when powered on. By following these parameters and precautions, the correct use and performance of the Omron SRM 1-C01/CO2-V2 main control unit can be ensured.
