Do not apply voltages other than those indicated in this manual on the connector. Doing
so may lead to destruction or damage.
∗
When using an inductive load such as relays, always connect a diode (withstand voltage
100V or more, 100mA or more) in parallel to the load as a noise measure.
∗
When using a capacitive load such as a lamp, always connect a protective resistor
(R=150
Ω
) serially to the load to suppress rush currents. (Make sure that the current,
including the instantaneous current, is less than the above tolerable current.)
