RBS Product Description
5.2 Environmental Impact
This section describes the effects that the cabinet has on the environment.
5.2.1 Heat Dissipation
The RBS 2106 (RBS 2106, RBS 2106i or RBS 2106 V3) generates an average
heat load of 3000 W. The exact figure is dependent upon configuration,
equipment, and site-specific conditions.
5.2.2 Acoustic Dispersion with Combined Climate Unit
The cabinet noise dispersion for an RBS 2106 (RBS 2106, RBS 2106i or
RBS 2106 V3) with Combined Climate Unit is shown in the tables below. The
figures and tables show the noise dispersion generated by a free-standing
cabinet and by a cabinet mounted against a wall.
Note: 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. Deviations from these values can be experienced due to the
nature of materials in the environment where the cabinet is installed.
Objects near the cabinet can reflect or absorb sound and thus affect
acoustic dispersion.
The following two tables show the sound pressure levels, calculated at the
bystander position at a distance of 1 metre from the cabinet and 1.5 metre
above the floor. The calculations are valid in free field. If the RBS is placed in a
room the sound pressure level will be higher than indicated in the tables below.
