900-001_IFU_V1.0_11270-S0-20130118-EN ARC PLUS Operating Manual 15
Connection to the AC mains
Connect the device directly to the AC mains.
Caution: To avoid the risk of electric shock, always connect the device to a
supply network with a protective earth lead.
If the ARC PLUS forms part of a medical electrical system, the requirements
in Section 16 of IEC 60601-1:2005 must be observed.
If a medical electrical system is formed with the ARC PLUS by use of a
multiple socket-outlet as a separate unit, a warning must be present to
indicate that this multiple socket-outlet may not be placed on the floor.
Avoid using multiple socket-outlets.
Do not use any additional multiple socket-outlets or extension cables.
Always ensure that the installation conforms to the allowable limits for leakage
current and protective earth lead resistance. These limits may be exceeded if
several devices (medical and non-medical) are connected to a multiple
socket-outlet. The totality of devices connected to a multiple socket-outlet
form a system and must be regarded as a unit.
If a multiple socket-outlet is powered from an isolation transformer, ensure
that no part of the system is at the same time powered from the regular
supply mains, as otherwise galvanic isolation will no longer be present.
If a multiple socket-outlet not powered from an isolation transformer is used,
connections to devices used for medical purposes must only be possible with
the aid of a tool.
2.4.2. Correct use of the argon device
Endoscopic use
In laparoscopic surgery the argon entering the body cavity increases the
abdominal insufflation pressure (CO
2
), unless a suitable arrangement to
compensate for the pressure rise is provided.
We recommend using an insufflator with pressure monitoring.
To prevent potential damage to the camera optics, do not aim the argon
plasma jet at the camera chip.
2.4.3. Correct connection and use of the argon gas bottle
Observe the safety instructions of the gas supplier. Only personnel trained to
deal with pressurised gas containers may handle these containers.
Always transport gas bottles with the valve protector fitted, and avoid exerting
force on the bottle and the pressure reducer.
Observe the use instructions for the pressure reducer that is used.
The maximum permissible inlet pressure at the device for operation from
bottled gas is 4.5 bar.
Use only argon with purity grade 4.8 or better.
Protect the bottle against heating from external sources, such as open flames
or radiators.
Use only pressure reducers approved by BOWA.
