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 by half.
Connection
With the SSR for DC switching, the load can be connected to either
positive or negative output terminal of the SSR.
Protective Component
Since the SSR does not incorporate an overvoltage absorption
component, be sure to connect an overvoltage absorption
component when using the SSR under an inductive load.
