Concerning equipment, accessories, disposable and parts refer to section ‘warnings and cautions’ of the User’s Guide for the
LuMon™ System [1].
8.2 Interfaces - Pin assignment
The mains power supply of the LuMon™ Monitor is separated by two Means of Patient Protection (MOPPs) between the belt
connector socket (for the applied part, the belt) and the interface connectors.
The interface connectors (serial ports, USB ports, Ethernet port) of the LuMon™ Monitor are not separated from each other. If at a
time accessory equipment is connected to only one of the interface connectors no additional safety measures are necessary to
comply with the requirements of IEC 60601-1. If, however, accessory equipment is simultaneously connected to two or more of the
LuMon™ Monitor’s interface connectors additional safety measures may be required to be compliant with the requirements of IEC
60601-1. In case of doubt consult qualified technicians .
