15. A method for cooling and monitoring electrical/electronic equipment comprising:
supplying a cooling fluid to a housing of the electrical/electronic equipment via a cooling fluid supply apparatus of the electrical/electronic equipment, the cooling fluid supply apparatus being coupled to the housing, the cooling fluid supply apparatus including a cooling fluid inlet apparatus, a cooling fluid discharge apparatus on the housing, and a cooling fluid guide apparatus within the housing connecting the cooling fluid inlet apparatus and cooling fluid discharge apparatus, the cooling fluid supply apparatus supplying the cooling fluid to the housing via the cooling fluid inlet apparatus;
opening a safety switching apparatus that is allocated to the cooling fluid inlet apparatus and having the cooling fluid flow into the housing;
closing the safety switching apparatus in response to at least one of a pressure drop in the cooling fluid supply apparatus and a temperature within the housing being above a predetermined temperature; and
interrupting a voltage supply to the electrical/electronic equipment when the safety switching apparatus closes;
wherein closing the safety switching apparatus includes moving a valve body of the safety switching apparatus into a closed position, wherein the valve body interrupts the voltage supply to the equipment upon reaching the closed position, and
wherein the cooling fluid has a boiling temperature lower than a permissible temperature of the equipment such that in the event of a fault evaporation of the cooling fluid causes the pressure within the housing to rise whereby the valve body is moved to th eclosed position thereby interrupting a power supply to the electrical/electronic equipment.
