5. Precautions for Use
- Environment: Avoid installation in areas directly exposed to rain, strong magnetic fields, or near objects with thermal radiation.
- Load Protection: Switching inductive or capacitive loads may produce peak voltage or current. Protection circuits are recommended to prevent relay damage.
- Mechanical Shock: Excessive mechanical shock may cause relay malfunction.
- Soldering: For wave soldering, maximum temperature is 260°C for no more than 5 seconds.
