Electrical requirements
The AAnalyst 700 spectrometer requires a stable electrical supply of 230 V,
50 Hz or 60 Hz, capable of delivering 20 A, that has a correctly wired protective
earthing system (ground connection).
The line power cable has a 3-pole connector (line + neutral + protective earth),
conforming to IEC 309-2, rated for 20 A. The cable is 3 meters long.
The line power supply should be free of line transients in excess of 50 V peak. If
the electrical supply voltage produces large AC line voltage fluctuations, a
qualified electrician should install a voltage regulator between the electrical outlet
and the instrument.
The power demand of the graphite furnace is approximately 3600 VA, the
maximum graphite tube temperature is 3000 C. Monitoring of the energy
required for each user-defined furnace program reliably prevents the line power
supply from being overloaded.
The line power supply point must be within 3 meters of the rear of the
spectrometer.
We recommend that you connect the spectrometer, computer, printer, and any
accessories to the same phase of the line power supply and the same protective
earth.
The line power supply must conform with local safety regulations and be checked
by a qualified electrician before you connect the instrument to line power.
See the guides for the computer and printer and any other instruments for
information about their power requirements.
