Abstract: A power supply assembly including a plurality of power supply modules which can be operated in parallel and are inserted or can be inserted into a common switch cupboard or rack or into a plurality of switch cupboards or racks, each power supply module having an inverter branch for continuously supplying electric power to a load at the output in a load branch. The power supply assembly also has a bypass assembly that ensures the power supply when power supply through the inverter branch fails or is insufficient. The reliability of the power supply is enhanced if each of the power supply modules has a bypass which is connected to the load branch, in parallel to the inverter branch. The bypass is separated from the load branch when the inverter path works properly and in the event of failure of an inverter branch, can be automatically connected by a control circuit to the load branch in order to maintain power supply.

Abstract: A liquid cooling system having cooling units individually assigned to electronic component groups housed in a rack or a switchgear cabinet, which are to be cooled, and having a monitoring and control arrangement for monitoring a cooling temperature. Effective cooling and temperature monitoring is obtained because the cooling units are liquid cooling units and are connected via branch points to a common central liquid line system integrated into the rack or the switchgear cabinet. The control and monitoring arrangement is for monitoring the cooling temperature in the central liquid line system and for emitting an error signal when a predetermined or a predeterminable threshold temperature in a liquid return branch is exceeded, or when a predetermined or predeterminable threshold temperature difference between a temperature in an inlet branch and a temperature in the return branch is exceeded, or when the liquid flow falls below a predetermined or predeterminable threshold value.

Abstract: A frame support for a rack or a switchgear cabinet, having an electrification arrangement combined with at least one frame leg or profiled mounting element for supplying and/or removing electrical current to or from devices which can be connected with the frame support. Simple and definite electrical connecting possibilities for electrical devices are accomplished with the electrification arrangement having at least one separate electrification strip attached to a frame leg or profiled mounting element which is formed by a hollow profiled receiving element and is at least partially open on a long side and in at least one hollow space of the profiled receiving element contact rails or connection lines are installed in a manner protected against electric shock.

Abstract: A method and a device for detecting leaks in components conducting liquids by a sensor reacting to leaks. The component to be monitored is inserted into a closable envelope containing the leaked liquid. Electrodes are embedded into the envelope. The resistance and/or the capacitance between the electrodes is changed if leaking liquid enters the closed envelope. With a sensor connected to the electrodes, which reacts to the resistance and/or capacitance changes, a display and/or alarm signal is triggered. It is possible to monitor the entire component for leaks.
