6 INSTALLATION
6.1 Spatial requirements
High-frequency surgery units must only be operated in medically used rooms. The spatial
requirements, in regard to electric installation, affect e.g. the grounded conductor system, the
ground fault interrupt system, as well as measures for preventing electrostatic charges.
The unit is used in rooms in which personnel can pick up electrostatic charges, for example in
rooms with electrically nonconductive floors, thus touching the front panel of the units can lead
to a brief illumination of light diodes or seven-segment displays due to discharge of an electrostatic
charge. However, this occurrence does not change the settings on the front panel.
6.2 Set-up possibilities in the operating room
ICC model series units can be set up in principle on tables, consoles on ceiling suspensions or
wall- mounted arms, as well as on special equipment carts.
6.3 Power connection
High-frequency surgical units must only be connected via the power cord provided by the unit
manufacturer or one of equal quality equipped with the national test symbol to a correctly installed
hospital grade power socket. Here, no outlet power socket or extension cord should be used if
possible for reasons of safety. If their use is unavoidable, these must be equipped with a protective
ground in perfect working order. The power outlet must be secured with a fuse with at least 10 A
rated current.
6.4 Potential equalization
If necessary, the unit can be connected to the potential equalization of the room. This should
prevent low-frequency electrode currents, e.g. low-frequency leakage currents in a defective
protective ground system, from endangering the patient.
ICC model series units are equipped with a potential equalization connector on the unit back
panel according to DIN 42 801. In this way, the units can be connected via a potential equalization
line to a potential equalization terminal at the set-up location.
6.5 Danger of explosion
A potentially explosive atmosphere can result:
· From the release or dissipation of a potentially explosive mixture of anesthetics containing
oxygen or nitrous oxide.
· From the use of combustible skin cleansing and disinfection substances.
The spatial extent of the danger zone is defined in the standard IEC 60 601-1 section 37.5. and in
explosion safety regulations.
WARNING!
HF surgical units generate electrical sparks, and are thus a potential source of ignition. Set up the
HF surgical unit outside the danger area.
