Safety distance requirements (compliance boundaries) This section describes compliance with reference levels (based on basic restrictions) for general public and occupational exposure to radio frequency electromagnetic fields Installing base stations to ensure public safety
This equipment generates radio frequency energy, which has a thermal effect when absorbed by the human body. For this reason compliance boundaries specific to this equipment have been established. The thermal effects of radio frequency energy can exceed safety levels when a person is inside the established

compliance boundaries. Observe the compliance boundary, and make sure the general public has no access to areas inside the established boundaries. The information shown in Warnings and cautions provided section below is taken from the relevant section of Nokia ’s user manual containing warnings and cautions specific to the equipment. Installing base stations to ensure installer safety
Installation engineers need to be aware of the potential risk of the thermal effects of radio frequency energy and how to protect him/herself against undue risk. The information shown in Warnings and cautions provided section is taken from the relevant section of Nokia ’s user manual containing warnings and cautions specific to the equipment. Warnings and cautions provided
Reference safety distances
When working close to transmitter antennas, the proper safety distances must be observed. The minimum safe distance from an antenna is measured in metres.
Warning Do not go any closer to a live antenna than the compliance boundary. The radio frequency energy generated by the antenna poses a serious health risk.
Warning If performing installation or maintenance procedures on a BTS, make sure that all transmitters in the area are switched off.
When assessing the applicable boundaries, the European standards EN 50383, EN 50384, EN 50385 and Council Recommendation 1999/519/EC for occupational and general public electromagnetic exposure limits - see Annex A have been applied. The statements shown below are taken from the Nokia ’s user manual containing warning and cautions specific to the equipment.

Environmental requirements
Assessment applying SAR measurements
European standards EN 50383, EN 50384 and EN 50385 do not include specifications for whole body SAR measurements. Whole body SAR measurements are not required for transmitters that have maximum output power levels too low to result in exposure levels that can reach the whole body SAR compliance limits under any conditions. Whole body SAR exclusion power levels have been based on the worst case assumptions. For details, see the table below.
Table 6.
Whole body SAR exclusion power levels
Exposure category
Maximum output power (rms)
General public
Max power [W] = general public whole body SAR limit [W/kg] * 12.5 kg: 4-yearold child body mass = 1 W
Occupational
Max power [W] = occupational whole body SAR limit [W/kg] * 42 kg: 16-yearold worker body mass = 16.8 W
Localised SAR measurements can only be used when: 1.
The separation between the phantom and the outer surface of the energy generating element is 40 cm (15.6 in.) or less.
2.
The surface area of the energy generating element is less than 60 cm (23.6 in.) by 30 cm (11.8 in.).
3.
The frequency is in the range of 800 to 3000 MHz.
For the reasons above, SAR measurements are not applicable to Nokia Flexi WCDMA Base Station. Assessment of compliance boundary
The compliance boundary is defined as the area around the antenna shown in the Area around the antenna figure below. The antenna is located at the origo. Distances from the antenna are shown. The top and side views are shown in the Antenna side and top view figure below, in Picture 1 and Picture 2.

In tables 'Dimensions of compliance boundary in meters for general public (GP)' and 'Dimensions of compliance boundary in meters (Occupational)' the compliance boundaries are given for different power levels, including the typical and worst case levels. If an exposure limit, antenna, and/or configuration is used which does not correspond to the levels given in tables 'Dimensions of compliance boundary in meters for general public (GP)' and 'Dimensions of compliance boundary in meters (Occupational)', the compliance boundary must be re-calculated according to EN50383. The formula for calculating the compliance boundary using the farfield model, which is referenced in EN50383, is given in ANNEX B later in this section. This model is applicable for calculating the compliance boundary for the far-field region and over estimates the compliance boundary for the radiating near-field region, but is not applicable for calculating the compliance boundary for the reactive near-field region where the distance from the antenna is less than or equal to λ / 4.

ANNEX B: Far-field calculation method
This model is applicable for calculating the compliance boundary for the far-field region and over estimates the compliance boundary for the radiating near-field region, but is not applicable for calculating the compliance boundary for the reactive near-field region where the distance from the antenna is less than or equal to λ /4, which is 3.75 cm at 2000 MHz. Therefore, all calculations are valid when the compliance boundary is greater or equal to the antenna dimensions plus λ /4. The minimum safety distance (compliance boundary) in metres, or 'r min', is calculated according to the following equation:
r min
=
(G - L) / 10 N 10 Pout 4p S DN02152589

Formula for safety distances
The meaning of each formula component is as follows: .
.
G is the antenna gain (in dB)
.
L is the minimum cable losses (in dB)
.

DN7037979 Issue 2-0 en draft
N is the number of transmitter units per one antenna
Pout is the maximum power of one transmitter unit (in W) S is the maximum power density limit (in W/m²)

Requirements for Installation and Operation
Note In the far-field, the field calculation does not take into account the antenna size, which is assumed to be a point source. Therefore, when calculating the compliance boundary, the far-field data, antenna size and reactive field criteria have to be taken into account.

Power requirements
5.1
Grounding requirements Grounding is required to ensure personnel safety and to avoid electrostatic discharge which can damage the equipment. To protect the BTS from damaging overvoltages through antenna equipment, communication cables, or power supply lines, grounding cabling must be planned and installed before the installation of the base station. To avoid interference, it is recommended that large grounding systems are designed case-specifically. A power plug with a protective ground connection is not sufficient for Nokia Flexi WCDMA BTS. Grounding must have a fixed, non-removable connection.
Note Follow local requirements for earthing (grounding). The principles and requirements vary in different countries.
Observe the following recommendations when planning the BTS grounding: .
.
The grounding cable is connected with screws to the BTS grounding point. The minimum cross-section of the copper (Cu) grounding conductor is following: .
.
.
.
DN7037979 Issue 2-0 en draft
Grounding cable cross-section has to be more than any of AC or DC power feeding cable cross-section. When 220-240 VAC is used, power cables shall be 1.5 - 2.5 mm (15...13 AWG) and grounding cable 2.5 mm 2 (13 AWG).
2
When 100-110 VAC is used, power cables shall be 1.5 - 2.5 mm 2 (15...13 AWG) and grounding cable 4 mm 2 (11 AWG). When 48 VDC is used, power cables shall be 6 - 10 mm 2 (9...7 AWG) and grounding cable 6 mm 2 (9 AWG).

5.2
The earthing (grounding) resistance target of the BTS site is =10 Ω. If it is not possible to reach this target due to difficult conditions, for instance in areas such as solid rocks or dry desert, the earthing (grounding) resistance can be max. 150 Ω. The ground cable must be connected to a main grounding busbar. Route the ground cables as directly as possible from the equipment to the grounding point. Avoid unnecessary loops and sharp bending of the grounding cable. The ground cables should not be run parallel with power cables. The external antenna feeders must also be grounded according to the local legislation if the antennas are exposed to lightning.
Mains power requirements Warning Danger of lethal voltages! Make sure that the mains power breaker is off, and that the cabinet is properly earthed (grounded), before removing any connections from the cabinet.
Ensure that the site has a main switch for disconnecting the site power. The disconnecting device shall disconnect both input supply poles simultaneously. The cross-sectional area of the Main Earthing Conductor (PE) shall not be less than live and neutral conductors nor less than 6 mm 2. The impedance of the earth connection shall be as low as possible.

Power requirements
Flexi BTS site maximum power consumption consists of 2x30 W power feed to MHA + antenna tilt. Up to 50 W/ 100 W (single/dual) higher power consumption can exist in extreme conditions and in BTS output power overdrive situations. In possible short circuit cases (for instance, antenna line), power consumption can momentarily be higher.
Note Values are given for 2.1 GHz RF module. For other RF Module variants, there is max. +10 % power consumption increase.
The values do not include optional cabinet (FCOA) and optional site support (FCSA) power consumption. For microwave transmission sub-module case (FTFA), add max. 50 W. The estimated maximum heat load can be assumed to be the same as the power consumption values.
