Safety Precautions

■ Precautions for Correct Use

Please observe the following precautions to prevent failure to
operate, malfunction, or undesirable effect on product performance.

Connection

With the SSR for DC switching, the load can be connected to either
positive or negative output terminal of the SSR.

Precaution of Mounting Output Modules

With up to four G3R SSRs mounted closely and
side by side, 2-A loads can be switched.

9A1 10A1 11A1 12A1 13A1 14A1 15A1 16A15A1 6A1 7A1 8A11A1 2A1 3A1 4A1

Protective Element

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.

With a G3R SSRs mounted every other slot,
2-A loads can be switched.
