The invention discloses an assembly having an inverter for an electric drive of a vehicle. A direct current sensor for detecting a direct current flowing into the inverter is provided at a direct current input of the inverter, wherein the direct current sensor is connected to a processor for detecting a variable representing the direct current. The processor determines a short circuit in the inverter depending on the parameter and at least one further parameter on the inverter or on the electric motor connected to the inverter, and sends a message depending on this first determination. 本发明公开了一种具有用于车辆的电驱动装置的逆变器的组件，其中在逆变器的直流电流输入端处设置有用于获取流入逆变器的直流电流的直流电流传感器，其中直流电流传感器与用于获取表示直流电流的参量的处理器相连接，其中处理器取决于参量和在逆变器或连接至逆变器的电动马达上的至少一个另外的参数来确定逆变器中的短路，并且取决于此第一确定来发送消息。
