Abstract: An elevator suspension member arrangement includes a monitoring arrangement monitoring an integrity status of suspension members having electrically conductive cords. The monitoring arrangement includes: a generator generating phase shifted first and second alternating voltages; input and output connectors each establishing electrical contacts to cords in one of the suspension members; a voltage analyzer measuring and analyzing a neutral point voltage resulting from applying the first and second alternating voltages to first and second cords of the one suspension member; a supply circuitry having supply lines electrically interconnecting the generator with the input connectors; and a measurement circuitry including measurement lines electrically interconnecting the analyzer with at least one of the input connectors and the output connectors. The supply and measurement lines are separated from each other whereby disturbing influences of impedances through the supply circuitry is minimized due to voltage measurements being performed through the separate measurement circuitry.
