multiple socket-outlet.
NOTE

PLM-8000 Operation Manual
V
CAUTION
Maximum permissible load of each socket-outlet used for the PLM-
8000 system, shall not be less than 100VA.
CAUTION
If non-medical electrical equipment (e.g. Video monitor, IT equipment,
etc.) that may be connected with PLM-8000 are, directly connected to
the wall socket-outlets, high touch current may flow since the earth
continuity is not ensured.
CAUTION
Multiple socket-outlet should be a grounding-type and complied with
IEC 60884-1.
CAUTION
Connection of the plug shall be possible only by using the tool.
(Refer to the figure below.)
NOTE
SAFETY INFORMATION - Accessory equipment connected to the
analog and digital interfaces must be certificated according to the
respective IEC standards (e.g. IEC 60950-1 for data processing
equipment and IEC 60601-1 for medical equipment). Furthermore all
configurations shall comply with the system standard EN 60601-
1:2006, Clause 16. Everybody who connects additional equipment to
the signal input part or signal output part configures a medical system,
and is therefore responsible that the system complies with the
requirements of the system standard (IEC 60601-1:2005, Clause 16).
If in doubt, consult the technical service department or your local
representative.
