Use within the rating (250V AC 0.5A).
Overvoltage and overcurrent may cause breakdown of the relay as well as
shortening its life.
It is recommended to connect a spark killer etc. to the connected load
according to AC/DC (refer to the connection examples). With a noise killer,
you can make the life of the relay longer as well as making it resistible against
noise.
Never short-circuit the load. Should you do it, the equipment will break down.
