Equipment
When selecting locations for each Information Center components, consideration should be
Cabling
given to the lengths of cables required for interconnections. Standard length, interconnection
cables are provided with each component, but other cable lengths are available as options.
For available cable options, see M3181A Cable Options for Information Center
Systems and 78599AI Cable Options for Remote Slave Display.
Note If the Remote Slave Display is located sufficiently far from the PC, extended length cabling is
required. This is described in the 2-Way Video Splitter Installation Note and 6-Way Video
Splitter Installation Note and illustrated in Chapter 5 Hardware Installation.

Safety

Medical Device
Any medical device that connects directly to a patient, such as bedside monitors, must comply
Standards with IEC 60601-1, IEC 60601-1-1, and IEC 60601-1-2, the international safety requirements
for medical electrical equipment. Any equipment that connects directly to a bedside monitor
creates a medical electrical system that must also comply with IEC 60601-1-1. In practice,
this means that the combined chassis leakage current of a medical device connected directly
to a patient and any directly interconnected device must be less than 500 mA (300 mA in the
U.S.)
IEC 60601-1-1 does allow, however, for the use of other equipment in a medical environment
provided that it complies with the relevant IEC standard and is not directly connected to a
patient. Relevant IEC standards are IEC 60950 for computer equipment and IEC 61010 for
laboratory equipment.
Philips Device Philips workstations, server, displays, LaserJet printers, and active Network components may
Requirements
be connected to bedside monitors through the Clinical Network and SDN provided that they
are located outside the patient environment and provided that the PCC or telemetry mainframe
contains a redundant Protective Earth connection. PCC redundant Protective Earth
connections are described in the Information Center Installation and Service Manual.
When the PCC and telemetry mainframe are properly installed, the resulting system complies
with IEC 60601-1-1.
Patient
None of the Information Center or Database Server equipment is approved for use within the
Environment patient environment. Figure 4-14 shows acceptable distances from the patient environment
beyond which all Philips equipment must be located.
Warning Information Center workstation, server, displays, recorder, LaserJet Printer, and
Clinical Network components are not approved for placement within the patient
environment -- any area within 1.5 meters (4.9 ft.) horizontally and 2.5 m (8.2 ft.)
vertically above the floor from any patient care location in which medical diagnosis,
monitoring, or treatment of the patient is carried out.
