Case 1: Medical Device Combined with Medical Device
If you combine a medical device with another medical device (incl. Philips specified displays) to form a
medical electrical system according to IEC 60601-1:2005+A1:2012/EN 60601-1:2006+AC:2010, no
additional protective measures are required. The medical electrical devices may be located in or outside
the patient vicinity in a medically used room. This is valid as long as the medical devices are connected
to separate mains outlets. No system test is required.
If the combined medical devices are connected to the same multiple portable socket outlet an
enclosure leakage current test of the entire device combination on the multiple portable socket outlet is
required to ensure that the resulting protective earth leakage current and equipment leakage current
does not exceed the limits of IEC 60601-1:2005+A1:2012/EN 60601-1:2006+AC:2010. Avoid using
multiple portable socket outlets. The medical electrical devices may be located in or outside the patient
vicinity in a medically used room. If the limits are exceeded, additional protective measures are
required, e.g. a separation device or the connection of each device to separate mains.
