Operation Manual
Electrical Safety
This equipment has been verified as a Class I device with Type BF applied parts.
CAUTION:
X
As for US requirement, the LEAKAGE CURRENT might be measured from a center-tapped circuit
when the equipment connects in the United States to 240V supply system.
X
To help assure grounding reliability, connect to a “hospital grade” or “hospital only” grounded
power outlet.
Prevention of Electric Shock
In a hospital, dangerous currents are due to the potential dierences between connected equipment
and touchable conducting parts found in medical rooms. The solution to the problem is consistent
equipotential bonding. Medical equipment is connected with connecting leads made up of angled
sockets to the equipotential bonding network in medical rooms.
[Figure 1.1 Equipotential bonding]
Additional equipment connected to medical electrical equipment must comply with the respective IEC
or ISO standards (e.g. IEC 60950 for data processing equipment). Furthermore all configurations shall
comply with the requirements for medical electrical systems (see IEC 60601-1-1 or clause 16 of the 3
Ed. of IEC 60601-1, respectively). Anybody connecting additional equipment to medical electrical
equipment configures a medical system and is therefore responsible that the system complies with the
requirements for medical electrical systems. Attention is drawn to the fact that local laws take priority
over the above-mentioned requirements. If in doubt, consult your local representative or the technical
service department.
