Selecting the frequency
• After unpacking the instrument and setting it up at its intended location,
use the lever (1) to select the frequency corresponding to the conditions
of the existing power system.
After transporting, wait at least 4 hours before turning the instrument on. This waiting peri-
od is necessary to allow the compressor oil, which may have been displaced during trans-
port, to return into its original position. Furthermore, any condensation that has formed dur-
ing this time due to temperature fluctuations must be allowed to dry completely.
Failure to comply with this can cause severe damage to the instrument!
During the start-up of the compressor the nominal voltage must not drop below the values
specified in the "Technical data" !
Please note that the compressor requires a start-up current between 25 and 35 A.
Therefore, the electric circuit at the installation site must be inspected by an electrical
engineer to ensure that it meets the requirements for a smooth operation of the instru-
ment.
Failure to comply with the above will cause severe damage to the instrument!
• Check power supply voltage and frequency to comply with the specifica-
tion on the type plate ( see Fig. 1 ).
• Do not connect any other appliances to this electric circuit.
Never connect the instrument to a power socket that does not have a protective conduc-
tor terminal.
