Regarding the increase in temperature, the start-up time cannot exceed the value indicated in the table.
In the event of repeated starts at unchanged rated power, the motor must, before each start-up, have the same temperature as before
the first start-up; to ensure the values in the table, it is assumed that the motor is cold.
