SAFETY INFORMATION
1) MAINS SUPPLY
The mains supply to the monitor (220 V a.c. Europe
the monitor metal frame, by means of the earth post provided, to ensure maximum protection from electric
shock, as required by international standards for Class I apparatus.
2) X-RADIATION
The chassis has been designed to avoid x-ray radiation; moreover, a special safety circuit guarantees that
radiation ever exceeds 0. 5 mR/h, never under fault conditions.
3) E. H.T.
Dangerous high voltages are present inside the monitor that could be harmful to personnel. For any
servicing requirement, it is recommended to call upon specialized personnel.
4) CATHODE-RAY TUBES
The cathode-ray tubes used in Hantarex monitors are constructed and certified to be implosion resistant.
They are, however, high vacuum components whose surfaces are subjected to high external pressure. It
is therefore necessary to take care to avoid knocking them with the risk of possible implosion and possible
flying glass splinters. It follows that personnel involved in their installation should use gloves, spectacles,
and protective clothing whenever inserting or substituting a cathode-ray tube.
5)
WARNING!
a)
Whenever voltage checks are to be made in the primary circuits of the power suppply, using a digital
voltmeter or an oscilloscope, it is necessary to isolate the monitor from the mains supply by means of an
ISOLA TING TRANSFORMER also taking care that the instruments are disconnected from earth.
This precaution is not necessary when making measurements in the monitor section (deflexion and
video), nor in the secondary circuits of the power supply.
b)
The isolating transformer for the above purpose should have following characteristics:
Input 220-240 V a.c.; Output 220-240 V a.c. 200 W minimum
c)
Following any inspection on the power supply unit, the metal safety cover and the screen below the
printed circuit board must both be replaced as well as the relative earthing cable.

SAFETY STANDARDS
POLO monitors are certified by IMO in accordance with the CEI 74/2 (EN 60950 Europe) standard. Class
with earth connexion.
The electronic circuit of POLO monitors destined for the USA are made in compliance with the UL 1950
(FILE E 106786) and CSA-C 22.2 n. 950 (FILE LR 94960) safety standards.
RECOMMENDATIONS FOR INSTALLATION IN OTHER EQUIPMENT
1) The mains input connector should be easily accessible and it and the connecting cable should be rated
for the total power consumption of the machine, as provided for in the EN 60950 standard (e.q. up to 6A
capacity with a length not exceed ind 2 m and a cable cross section of 0. 75 mm2).
2) Extension cables are not to be used with the risk of poor contact and consequent overheating and fire
hazard.
3) The structure into which the monitor is mounted must provide for complete protection from any accidentally
spilt liquid entering the inside of the monitor.
4) The monitor must not be used in excessively high ambient humidity so as to prevent electric discharge.
5) The machine must be provided with a double pole switch to provide for instant isolation whenever
necessary.
6) The mains input supplying the machine, in addition to being switched, must be positioned in the immediate
vicinity of the switch and be easily accessible.
7) The machine should not be exposed to direct sunlight which would cause overheating.
All the above suggestions are directed to satisfac tory operation, long life and complete safety and protection
of operators and users.
