Safety Precautions
■Precautions for Correct Use
Please observe the following precautions to prevent failure to
operate, malfunction, or undesirable effect on product performance.
The SSR case serves to dissipate heat. Install the relays so that they
are adequately ventilated. If poor ventilation is unavoidable, reduce
the load current to half.
