Natus Quantum Amplifier
21
To avoid the possible hazards caused by the summation of leakage currents when all the
parts of the system are interconnected, no equipment other than devices connected to the
Quantum Amplifier system may be powered by the isolation transformer.
The current rating of the isolation transformer must be sufficient to operate all of the devices
powered by it. Refer to the current ratings of the isolation transformer and current rating for
each individual device connected.
Do NOT connect non-medical equipment which has been supplied as part of the system
directly to the wall outlet when the system is supplied, via MPSO, with a separating
transformer.
Do NOT connect electrical equipment which has not been supplied as a part of the system to
the MPSO.
Ensure that the Quantum Amplifier system is solely connected to a three-wire, grounded,
hospital-grade receptacle.
3.2.4. Patient Environment Warnings and Cautions
NOTE:
The patient environment is defined as the area within 1.5 meters of the patient
laterally and within 2.5 meters of the floor in the area occupied by the patient.
Connect all patient electrodes to fully electrically isolated physiological devices only.
Connecting patient electrodes to any other device or external outlet may result in personal
injury.
If a computer is located in the patient environment and is connected to a network, the
computer and other hardware connected to it
MUST
be powered using an isolation
transformer, and a network isolator
MUST
be used
to isolate the computer from the site’s
LAN.
The patient event button attached to the Quantum Amplifier system is NOT intended for
critical patient-safety-related incidents.
Patient connections are
NOT
intended for direct cardiac contact.
As with all medical equipment, carefully route patient cabling to reduce the possibility of
patient entanglement or strangulation.
Do
NOT
touch any Quantum system accessible metal parts and the patient simultaneously.
