Acoustical Noise Emissions
The equivalent continuous A-weighted sound pressure level at workstations (emission sound pressure
level at the 1-meter bystander positions) does not exceed 70 dB(A).
Der Geräuschpegel der Einheit ist kleiner oder gleich 70 db(A).

1. Noise emissions data are based on the following configuration: the drawer is mounted in a 7014 Series Model
T00 Rack, a power distribution unit is installed in the rack, and the system is operating in a normal environment
of 25 °C (78 °F).
2. Noise emissions data are based on the following configuration: the drawer is mounted in a 7014 Series Model
T00 Rack and a power distribution unit is installed in the rack.
Noise Emission Notes
1. L
WAd
is the declared (upper limit) sound power emission level for a production series of machines.
2. L
pAm
is the mean value of the A-weighted sound pressure emission levels at the operator position (if
any) for a production series of machines.
3. <L
pA
>
m
is the mean value of the space-averaged A-weighted sound pressure emission levels at the
one-meter positions for a production series of machines.
4. N/A = Not Applicable (no operator position).
5. All measurements are made in accordance with ISO 7779 and reported in conformance with ISO 9296.
