D
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.
D
To avoid interference in the event that the Senographe is used in a domestic environment
(in a doctor's office, for example), it is recommended that it should be connected to a
separate AC power distribution panel and line, and it must be installed in an X–ray
shielded room.
D
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.
– We 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, which is itself
supplied by a single power line.
D
The Senographe should not be used adjacent to or stacked with other equipment. If
adjacent or stacked use is necessary, the Senographe should be monitored to verify
normal operation in the configuration in which it will be used.
D
In the case of a digital Senographe, the Gantry (with its digital detector) must be separated
by at least 1 meter from the generator cabinet, and 1 meter from the analog (CRT)
monitors. These specified distances minimize the risk of low frequency magnetic field
interference.
D
In order to avoid interference on the Senographe system, static field limits from the
surrounding environment are specified.
D
Static field is specified as less than 1 Gauss in the Examination room (Gantry room), and
in the Control Area (for all Subsystems).
D
Static field is specified as less than 3 Gauss in the Technical Room.
D
In order to reduce electrostatic discharge interference, a charge dissipative floor should
be installed to prevent charge accumulation.
D
The dissipative floor material must be connected to the system reference ground, if
applicable.
