Ground Vibrations
The RBS 2107 is designed to fulfill the requirements of earthquake protection
according to IEC 60 721-3-4 class/4M5/ and ETSI EN 300 019-1-4 class 4.1.
Levelling
To ensure that the cabinet is level, the floor must be level to within ±3 mm per
2000 mm and the floor gradient must be within ±0.1
.
4.2 Environmental Impact
This section describes the effects the cabinet has on the environment.
Acoustic Dispersion Heat Exchanger
The cabinet noise dispersion for an RBS 2107 with heat exchanger climate
unit is shown in the two figures below [TO BE DEFINED]. The figures 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
caused by materials in the environment where the cabinet is
installed. Objects near the cabinet can reflect or absorb sound
and thus affect acoustic dispersion.
Heat Dissipation
The RBS 2107 generates an average heat load of 1600 W. The exact figure
depends on configuration, equipment, and site-specific conditions.
4.3 Compliance Distances for Electromagnetic Exposure
The compliance distance is the minimum separation that should be kept
between the antenna and a person in order to ensure that the ICNIRP RF
exposure limits are not exceeded.
Note ICNIRP, "Guidelines for limiting exposure to time-varying
electric, magnetic, and electromagnetic fields (up to 300 GHz)",
International Commission on Non-Ionizing Radiation Protection,
Health Physics, vol. 74, no. 4, 1998.
Ericsson has performed a free-space near-field RF exposure assessment of
typical configurations of the RBS 2107 with a recommended antenna. The
resulting dimensions, in metres, for a compliance boundary for both public and
occupational exposure, are shown in table 4.
