Installation and Preparation
3-3
Do not use the DC power cord with any damage.
3.2.3 Protective Grounding
To protect both the patient and the operator, the housing of the monitor must be grounded. The monitor is
equipped with a detachable 3-wire power cord which shall be inserted into a grounded power outlet to ensure that
monitor is grounded. If a grounded power outlet is not available, contact the maintenance department in your
hospital.
To avoid the risk of electric shock, this equipment must only be connected to a mains supply with
protective earth.
Connect the ground wire to the equipotential connector of the monitor. If you have any doubt about whether the
equipment used may cause any electrical risks, such as the risk caused by the accumulation of leakage current,
consult a professional technician to ensure the safety of all equipment.
3.2.4 Equipotential Grounding
The monitor must be connected to a mains socket with protective grounding and the equipotential grounding
system. Use the green/yellow equipotential grounding cable and connect one end of the equipotential conductor
(potential equalization conductor) to the equipotential connector on the rear panel of the monitor and the other
end to a connector of the equipotential grounding system. In the event that the protective grounding system is
damaged, it can provide protection to the patient and operator.
If the protective grounding system is not stable, use the built-in battery to power the monitor.
If the use of the equipment is affected by the equipotential grounding, contact the Company’s After-
Sales Service Department or agents.
