A module is described which is slidably attachable to a controller. Resource wires are connected to the module through resource connectors. The module has a circuit board that can perform actions. The module can modify the function of its resource connectors. These modifications may be to meet the requirements of resources that are to be connected to the module. The module may be able to register, by means of a signal, when a correct resource wire is attached to the module. The results of such monitoring may be displayed on a screen associated with the controller.

Tools and techniques are described to create a controller wiring board. A user, using a user interface associated with a controller, can determine which devices will be attached to a controller. The features of the devices may be already known by the controller. The controller can change wiring terminal types depending on the requirements of the devices wired to the controllers. In some embodiments, a device is wired to a module associated with the controller. The controller can signal to the module to modify its wiring terminal to match the needs of the device to be wired to that location.

A power supply system including a plurality of energy storage units and a plurality of power converters, and the energy storage unit is electrically connected to a corresponding power converter. First controllers in the energy storage units sequentially control actions of the at least two switches. The second controller in the power converter obtains the direct current voltage received by the power conversion circuit; and when change amplitude of the direct current voltage is greater than a preset threshold, sends, through a communication connection, change information of the direct current voltage to the first controller that is communicatively connected to the second controller; otherwise, sends maintaining information of the direct current voltage. When controlling the voltage output by the direct current power supply to change, and when receiving the maintaining information of the direct current voltage, the first controller outputs a signal indicating a cable connection error.

The present invention relates to a method (200) for testing a wiring of an electrical installation (100) comprising multiple circuits. In the method (100), multiple test signals (160-162) are generated. Each of the multiple test signals (160-162) has an asymmetrical signal shape in the time domain and also a combination of harmonics from a predefined group of higher harmonics. The combinations of harmonics of the multiple test signals (160-162) are different. The multiple test signals (160-162) are fed at a first point (141) of the electrical installation (100) into multiple first connections (142-144), which are assigned to the multiple circuits. Multiple measurement signals are detected at multiple second connections (146-148), which are assigned to the multiple circuits, at a second point (145) of the electrical installation (100). On the basis of the fed test signals (160-162) and the detected measurement signal, assignments between a first connection of the multiple first connections (142-144) and a second connection of the multiple second connections (146-148) are determined.
