2-6. Installation Requirements and Environmental Control
• In order to minimize interference risks, the following requirements apply.
2-6-1. Cable Shielding & Grounding
• All interconnecting cables to peripheral devices must be shielded and properly grounded. Use of
cables not properly shielded and grounded can result in the equipment causing radio frequency inter-
ference.
2-6-2. Separated Power Supply Distribution Panel & Line
• This product complies with the radiated emission limits of the CISPR11 Group1 Class A standard.
• The Senographe is primarily intended for use in non-domestic environments, and not connected
directly to the public mains supply network.
It is primarily intended for use in environments (such as hospitals) with a dedicated supply system,
and in an X-ray shielded room.
• To avoid interference in the event that the Senographe is used in a domestic environment (in a doc-
tors office, for example), it is recommended that it must be connected to a separate AC power distri-
bution panel and line, and it must be installed in an X-ray shielded room.
2-6-3. Subsystem & Accessories Power Supply Distribution
• All components, accessories, subsystems, and systems which are electrically connected to the
Senographe must have AC power supplied by the same power distribution panel and line.
Note:
- You can not connect together different electrical devices and supply them by different AC power
distribution lines.
- In order to avoid interference, all components and accessories connected to the Senographe
must be connected to the same AC power distribution panel. This AC power distribution panel
which is itself supplied by a single power line.
2-6-4. Stacked Components & Equipment
• The Senographe must not be used adjacent to or stacked with other equipment. If adjacent or
stacked use is necessary, the Senographe must be monitored to ensure that normal operation
occurs in the configuration in which it is used.
2-6-5. Static Magnetic Field Limits
• In order to avoid interference on the Senographe system, static field limits from the surrounding envi-
ronment are specified.
• Static field is specified as less than 1 Gauss in the Examination room (Gantry room), and in the Con-
trol Area (for all Subsystems).
• Static field is specified as less than 3 Gauss in the Technical Room.
2-6-6. Electrostatic Discharge Environment & Recommendations
• In order to reduce electrostatic discharge interference, a charge dissipative floor must be installed to
prevent charge accumulation.
• The dissipative floor material must be connected to the system reference ground, if applicable.
• Relative humidity must be maintained above 30 percent.
