1. A method for producing a pulse inverter comprising a module with electronic components, a contact bar sticking out from a side of the module for contacting the pulse inverter with a contact external to the pulse inverter, a current measuring device arranged on the contact bar for detecting a measurement signal regarding a current strength in the contact bar and a control board arranged on a top or bottom of the module with a driver circuit for control of the electronic components in dependence on the measurement signal, wherein the driver circuit makes electrical contact with the module across control contacting pins of the module and with the current measuring device across measurement contacting pins of the current measuring device, the method comprising:
attaching the current measuring device to the contact bar such that the current measuring device is movably mounted with respect to the contact bar,
after attaching the current measuring device to the contact bar, positioning the control board such that the control contacting pins provided on the module are led through control contact openings of the control board,
orienting the current measuring device by displacing it such that the measurement contacting pins provided on the current measuring device are led through measurement contact openings of the control board, and
after orienting the current measuring device, securing the current measuring device to the contact bar and/or the control board.
