Preparing to Install the Monitor
Installing the Instrument 65
WARNING Disconnect the Monitor from the AC source by unplugging the power cable from the
AC source receptacle or from the AC power connector at the side of the Monitor. The
On-Off/Standby button does not disconnect the Monitor from the AC mains supply.
WARNING Do not operate the M3046A Monitor on a 2-wire AC supply
Connect the grounding wire to the equipotential grounding post on the Monitor:
Equipotential Grounding
To eliminate potential differences between different pieces of equipment, in the
medically used room, for internal examinations on the heart or the brain, the Monitor
must have a separate connection to the equipotential grounding system.
One end of the equipotential grounding cable (potential equalization conductor) is connected
to the equipotential grounding post on the side of the Instrument and the other end is
connected to one point of the equipotential grounding system.
Examinations in or on the heart (or brain) should only be carried out in medically-used rooms
incorporating an equipotential grounding system, according to national standards.
Combining Equipment
All combinations of medical equipment with non-medical equipment must comply with IEC
60601-1-1.
WARNING If instruments are combined, the summation of the leakage currents can be hazardous
to the patient or hospital personnel.
If it is not evident from the Instrument specifications whether a particular instrument
combination is hazardous or not, service personnel must apply measurements and
install appropriate IEC 60601-1 compliant means to make sure the combination is safe
(see Chapter 4, “Testing the Instrument”). In a likely case, the user must consult the
manufacturers to ensure that the summation of leakage currents does not jeopardize
patient safety.
