Verify that there is no continuity between SPK and -VSS at each module.
Verify that there is no continuity between the chassis and GND at the power supply.
Verify that there is no continuity between +VCC and GND at the power supply output.
Verify that there is no continuity between +VSS and GND at the power supply output.
Verify that there is no continuity between both mains inputs (live and neutral) and between each input and EARTH.
