Interference may occur in the vicinity of equipment
marked with the following symbol:
NOTE 1 These guidelines may not apply all situations. Electromagnetic propagation is affected by absorption
and reflection from structures, objects and people.
NOTE 2 It is essential that the actual shielding effectiveness and filter attenuation of the shielded location be
verified to assure that they meet the minimum specification.
a
Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and
land mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted
theoretically with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an
electromagnetic site survey should be considered. If the measured field strength in the location in which the
VZW2556 series of X-ray generators is used exceeds the applicable RF compliance level above, the X-ray
generator should be observed to verify normal operation. If abnormal performance is observed, additional
measures may be necessary, such as re-orienting or relocating the X-ray generator.

1.1.6 Electromagnetic Compatibility (EMC)
In accordance with the intended use, some models of this series of X-ray generators comply with the
European Council Directive concerning Medical Devices. The CE marking affixed to compliant products
signifies this. One of the harmonized standards of this Directive defines the permitted levels of
electromagnetic emission from this equipment and its required immunity from the electromagnetic
emissions of other devices.
It is not possible, however, to exclude with absolute certainty the possibility that other high frequency
electronic equipment, which is fully compliant to the EMC regulations, will not adversely affect the
operation of this generator. If the other equipment has a comparatively high level of transmission power
and is in close proximity to the generator, these EMC concerns (the risk of interference) may be more
pronounced. It is therefore recommended that the operation of equipment of this type such as mobile
telephones, cordless microphones and other similar mobile radio equipment be restricted from the vicinity
of this X-ray generator.

1.3.2 Generator Power Requirements (Cont)
The following table defines the power line requirements for the generators.
: THE FOLLOWING TABLE CONTAINS RECOMMENDED VALUES FOR THE WIRE SIZES BETWEEN
NOTE
THE MAINS DISCONNECT AND THE GENERATOR. THE ACTUAL VALUES USED AT AN
INSTALLATION ARE DEPENDENT ON THE QUALITY OF THE INPUT LINE (VOLTAGE LEVEL), THE
CURRENT REQUIREMENTS, AND THE LENGTH OF THE CABLE RUN, AND MUST BE CONFIRMED
BY THE INSTALLER.
FINAL SELECTION OF GENERATOR INPUT WIRE AND DISCONNECTS AS WELL AS THE
CABLING FROM THE DISTRIBUTION TRANSFORMER TO THE MAINS DISCONNECT MUST MEET
THE REQUIREMENTS OF THE LOCAL ELECTRICAL CODES, AND IS USUALLY DETERMINED BY
HOSPITAL / CONTRACTOR ENGINEERING.
THE RATINGS LISTED CONSIDER THE GENERATOR REQUIREMENTS ONLY. THE INSTALLER
MUST MAKE THE NECESSARY COMPENSATION FOR ADDITIONAL LOAD REQUIREMENTS.
A POOR QUALITY INPUT LINE MAY RESULT IN THE INSTALLER HAVING TO
DERATE THE GENERATOR'S MAXIMUM POWER.
