Ground Vibrations
The RBS 2106 is designed to fulfill earthquake protection according to
IEC 68–2–57.
Levelling
In order to level the cabinet, the floor must be level to within ±3 mm/2000 mm
and the floor gradient be within ±0.1°.
4.2 Environmental Impact
This section describes the effects that the cabinet has on the environment.
Heat Dissipation
The RBS 2106 generates an average heat load of 3000 W. The exact figure is
dependent upon configuration, equipment and site-specific conditions.
Acoustic Dispersion
The cabinet noise dispersion for an RBS 2106 with Combined Climate Unit is
shown in the two figures below. The figures show the noise dispersion
generated by a free-standing cabinet and by a cabinet mounted against a wall.

The acoustic noise dispersion values for a free-standing cabinet and
a cabinet installed against a wall were tested according to the ISO
9614-2 standard, however deviations from these values may be
experienced due to the nature of materials in the environment where
the cabinet is installed. Objects may reflect or absorb sound and will
affect acoustic dispersion.
