CAUTION
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.
