WARNING
AVERTISSEMENT
To ensure safe and satisfactory operation of the instrument, it is
essential that the green or green/yellow ground (earth) wire of the
power cord is connected to a ground that complies with the regulations
of the local electricity supply authority (or equivalent body); ground
circuit continuity is essential for safe operation of the equipment.
Pour assurer un fonctionnement sûr et satisfaisant de l'instrument, il
est essentiel que le fil de terre vert ou vert / terre du cordon
d'alimentation soit raccordé à un sol conforme à la réglementation de
l'autorité locale d'alimentation électrique (ou du corps équivalent) ; La
continuité du circuit au sol est essentielle pour un fonctionnement sûr
de l'équipement.
Only connect equipment that meets the requirements of IEC 61010-1, IEC 60950 or
equivalent standards.
A Spectrum Two N has:
• An IEC Installation Category (Overvoltage Category) II classification - suitable for
connection to local level power supplies.
• An IEC Pollution Degree 2 classification - usually only non-conductive atmospheric
pollution of the equipment occurs; occasionally, however, a temporary conductivity
caused by condensation must be expected.
The power supply adaptor has been designed to be safe under the following environmental
conditions:
• Indoor use
• Altitude up to 2000 m (above mean sea level)
• Ambient temperatures of 0 °C to 50 °C
• Mains supply fluctuations not exceeding ±10% of the nominal voltage.
If it is necessary to fit a plug on the power cable supplied, use the wire color code below:
Plug Pin Wire Color (100–120 V) Wire Color (220–240 V)
Ground (Earth) Green or Green/Yellow Green/Yellow
Live Black Brown
Neutral White Blue
Optical radiation
The instrument complies with the requirements of the Artificial Optical Radiation Directive
2006/25/EC.
