M3A Vital Signs Monitor User Manual

1.2.4 Equipotential Grounding

Protection class 1 instruments are already included in the protective grounding (protective earth)
system of the room by way of grounding contacts in the power plug. 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 terminal on the rear panel of the instrument and the
other end to one point of the equipotential grounding system. The equipotential grounding system
assumes the safety function of the protective grounding conductor if ever there is a break in the
protective grounding system. Examinations in or on the heart (or brain) should only be carried out
in medically used rooms incorporating an equipotential grounding system. Check each time
before use that the instrument is in perfect working order. The cable connecting the patient to the
instrument must be free of electrolyte.
If the protective grounding (protective earth) system is doubtful, the monitor must be
supplied by internal power only.

1.2.5 Condensation

Make sure that during operation, the instrument is free of condensation. Condensation can form
when equipment is moved from one building to another, thus being exposed to moisture and
differences in temperature.

1.2.6 Safety Precautions

WARNING and CAUTION messages must be observed. To avoid the possibility of injury,
observe the following precautions during the operation of the instrument.
