Page 8: Supply Voltage
Never open a power supply unit cause dangerous voltages can even exist after it has been disconnected from the electrical supply. If a power supply is not working anymore, e.g. due to a defect, please send it back to Meinberg for necessary repairs. Non-observance of these safety instructions can cause serious personal injury and material damage. Installation, initial start-up and operation of the IMS System may only be performed by qualified technical experts. -
