Safety Precautions
■ Precautions for Correct Use
Please observe the following precautions to prevent failure to
operate, malfunction, or undesirable effect on product performance.
Connection
The SSR for DC switching use can connect to a load regardless of
the polarity of the positive and negative output terminals.
Close Mounting of Multiple Relays
If multiple Relays are mounted side by side, be aware that the outer
wall of each SSR works as a heat sink.
The SSR casing serves to dissipate heat. Install the Relays so that
they are adequately ventilated. If poor ventilation is unavoidable,
reduce the load current by half.
Protective Terminal
No overvoltage absorption element is built in. (The G3HD-202SN
has a built-in varistor.) Be sure to connect an overvoltage absorption
element when using the G3H or G3HD with an inductive load.
EMC Directive Compliance
