2. Installation
2.1 Requirements to Personnel
The installation of the system should be carried out by a person who is empowered by
the manufacturer or the technical personnel of the medical institution which is going to
use it. It is necessary to remember that digital system mounting accuracy defines
safety and quality of operation. Further mounting and setting requirements which de-
fine the product safety will be marked by bold and italic fonts in the text.
2.2 Room Selection and Placement
Before mounting and setting of digital system, it is necessary to select a place for it,
taking into consideration power wiring and protective ground in the room. Please, read
the following requirements and recommendations:
Requirements concerning the room selection and equipment placement:
 Place the system at the maximum possible distance from power cables, switch-
boards, and different powerful electrical devices which can emit electromagnetic
fields of mains frequency.
 The distance from the electronic units to the nearest electric mains is not less than
1,5 meters.
 Do not place the system in the immediate vicinity (less than 5 meters) to short-wave
or microwave therapeutic equipment (it can lead to its unstable operation).
 The patient environment (within 1.5 meters) should contain only the system
parts being the medical devices with the required safety level (according to
EN 60601-1) or system parts connected only via isolation transformer that
satisfies the above-mentioned requirements.
 The safety level of computer equipment connected without isolation trans-
former is insufficient for the use in the patient environment. Hence, a patient
must not contact with the metal parts of computer equipment cases and
the personnel must not touch simultaneously these parts and patient body.
Requirements to mains:
 Do not use electric mains where the neutral conductor and protective ground
are combined. It is strongly prohibited.
 To avoid electrical shock, the mains plug must only be inserted in an appro-
priate mains socket outlet provided with a protective earth (ground) contact.
