SAFETY
Electrical
This product is intended to be operated from a mains power source of nominally 100 to 230V~, 47 to 63 Hz and
Maximum AC Power consumption: 45VA.
WARNING: To prevent electrical hazards to all personnel, this monitor must be properly grounded. Connect the
monitor only to a three-wire, grounded, hospital grade receptacle. The three-conductor plug must be inserted into a
properly wired three-wire receptacle; if a three-wire receptacle is not available, a qualified electrician must install
one in accordance with the governing electric code.
WARNING: Do not under any circumstances remove grounding conductor from the power plug.
WARNING: The power cable supplied with this equipment provides for this protection. Do not attempt to defeat
this protection by modifying the cable or by using ungrounded adapters or extension cables. The power cord and
plug must be intact and undamaged. To disconnect the equipment from the mains power; unplug the power cord.
WARNING: Do not connect to an electrical outlet controlled by a wall switch or dimmer.
WARNING: If there is any doubt about the integrity of the protective ground conductor arrangement, do not
operate the monitor until the AC power source protective conductor is fully functional.
WARNING: Do not place the monitor in any position that may cause it to fall on the patient. Do not lift the
monitor by the power supply cord or patient cable.
WARNING: Electric shock hazard! Do not remove covers or panels. Refer service to qualified service
personnel.
WARNING: To avoid electrical shock, disconnect the monitor from its power source before changing fuses.
Replace fuses only with same type and rating T.5A, 250V (Metric 5x20mm).
WARNING: Do not clean monitor while it is on and/or plugged into a power source.
WARNING: If unit is accidentally wet, discontinue use until dry and then test unit for proper operation before
reuse on a patient.
WARNING: This unit uses a common isolation path for the ECG leads. Do not connect any non-isolated
accessories to the ECG input when connected to a patient, as this may compromise the safety of the unit. When
attached to other devices, insure that the total chassis leakage currents of all units do not exceed 300 μA.
Explosion
DANGER: Explosion hazard! Do not use this equipment in the presence of flammable anesthetics or other
flammable substance in combination with air, oxygen-enriched environment or nitrous oxide.

SAFETY
Model 3150-B Operation Manual 3
Patient Connections
Patient connections are electrically isolated. For all connections use isolated probes. Don’t let patient connections
contact other conductive parts, including ground. See instructions for patient connections in this manual.
Carefully route patient cables to reduce the possibility of patient entanglement or strangulation.
Leakage current is limited internally by this monitor to less than 10 μA. However, always consider cumulative
leakage current that can be caused by other equipment used on the patient at the same time as this monitor.
To ensure that the leakage current protection remains within the specifications, use only the patient cables specified
in this manual. This monitor is supplied with protected lead wires. Do not use cables and leads with unprotected
lead wires having exposed conductors at the cable end. Unprotected lead wires and cables may pose an
unreasonable risk of adverse health consequences or death.
Line isolation monitor transients may resemble actual cardiac waveforms and thus inhibit heart rate alarms. To
minimize this problem, ensure proper electrode placement and cable arrangement.
If an alarm condition occurs while the alarms are set to off, neither visual nor audio alarms will be present.
MRI
The Model 3150-B should not be used within the magnetic field during Magnetic Resonance Imaging.
Pacemakers
Rate meters might continue to count the pacemaker rate during occurrences of cardiac arrest or some arrhythmias.
Do not rely on rate meter alarms. Keep pacemaker patients under close surveillance.
Electrosurgery Protection
This equipment is protected against electrosurgery potentials. To avoid the potential of electrosurgery burns at
monitoring sites, ensure proper connection of the electrosurgery return circuit as described by the manufacturer’s
instructions. If improperly connected, some electrosurgery units might allow energy to return through the ECG
electrodes.
Defibrillation Protection
This equipment is protected up to 360 J defibrillator discharge. The monitor is internally protected to limit current
through the electrodes to prevent injury to the patient and damage to the equipment as long as the defibrillator is
used in conformance with the manufacturer’s instructions.
EMC
This equipment has been certified to be protected to emissions and immunity according to IEC-60601-1-2.
Electromagnetic Compatibility IEC 60601-1-2:2001
