continuously applied to the coil and contacts, and then
turned OFF and immediately ON again, the coil temperature,
and consequently the coil resistance, will be higher than
usual. This means that the mustoperate voltage will also be
higher than usual, exceeding the rated value (“hot start”). In
this case, take the appropriate countermeasures, such as
reducing the load current or restricting the energizing time or
ambient operating temperature.
WARNING
Take measures to prevent contact with charged parts
when using the Relay for high voltages.
