An air filter must be used together with the BTS cabinet when standard-based operational environmental conditions presented in Environmental specifications and requirements for a stand-alone BTS are exceeded. Typically, a cabinet with an optional air filter is needed: • in places where dust is a concern • next to a dusty road with heavy traffic • in sandy terrain with the possibility of wind-blown sand in the air • next to an industrial plant with significant emissions of dust or other particles, such as cement factory, sawmill, and so on • nearby a cornfield with heavy straw dust during harvesting • in places where salt fog or acid rain caused by air pollution is a concern • in site locations where surrounding metal structures show signs of corrosion because of the extreme conditions (salt in air) • in locations with especially heavy rainfall and high humidity combined with air pollution • near sea shore: – with dense salt fog because of the breaking waves – with dense salt fog and line of sight to the sea (not behind a large building) – where wind-driven salt fog from sea can be identified Flexi Multiradio BTS LTE Installation Site Requirements Environmental requirements Issue: 01A DN0951839 15 For a generic model for sea salt distribution, see Figure 2: Sea salt distribution over land masses. Typically, the further away from the sea the BTS is located the less salt is accumulated. However, because of the local environmental variables a general rule for determining the distance cannot be stated. Always check the local environmental conditions before installing a BTS in the proximity of the sea.

Ensuring 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 the section Warnings and cautions provided is taken from the relevant section of NSN product documentation containing warnings and cautions specific to the equipment. 1) According to GR-487-Core specification Flexi Multiradio BTS LTE Installation Site Requirements Environmental requirements Issue: 01A DN0951839 23 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 themselves against undue risk. The information shown in the Warnings and cautions provided section is taken from the relevant section of NSN product documentation 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. f The antenna generates electromagnetic fields at radio frequencies. Do notcross the compliance boundary. f This equipment generates electromagnetic fields. If performing installation ormaintenance procedures on the antenna systems, make sure that all the 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 NSN product documentation containing warning and cautions specific to the equipment. Assessment applying Specific Absorption Rate (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 Table 16: Whole body SAR exclusion power levels. Table 16 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-year- old child body mass = 1 W Occupational Max power [W] = occupational whole body SAR limit [W/kg] * 42 kg: 16-year-old worker body mass = 16.8 W Localized 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. Environmental requirements Flexi Multiradio BTS LTE Installation Site Requirements 24 DN0951839 Issue: 01A For the reasons above, SAR measurements are not applicable to Flexi Multiradio Base Station. Assessment of compliance boundary The compliance boundary is defined as the area around the antenna shown in Figure 3: Area around the antenna. The antenna is located at the origo.

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 far-field 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.

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 'rmin', is calculated according to the equation in Figure 6: Formula for safety distances: Figure 6 Formula for safety distances DN02152589 The meaning of each formula component is as follows: • N is the number of transmitter units per one antenna • G is the antenna gain (in dB) • L is the minimum cable losses (in dB) • Pout is the maximum power of one transmitter unit (in W) • S is the maximum power density limit (in W/m²) Note that 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.

Site security is established so the BTS and other units can remain undisturbed at the site. 11. Make sure you can take the BTS to the installation site. For example, in roof top installations, the hole through which you take the BTS to the roof must be large enough. 6.2.1 Indoor site requirements If installing the BTS to an indoor site, ensure that the following indoor BTS site requirements are met: • Door and lock to site room are properly installed and operational (recommended). • Access to the site is secure. • The site is adequatelylit. • Feeder entry hole and cable rack for feeder and power cables are ready, if needed. • Heater, or air conditioner, is installed and operational, if needed. This depends on the heat emission and the environment. 6.2.2 Choosing site for the Remote Radio Heads f CAUTION! Risk of personal injury.The unit might have very hot surfaces when operating in hot environments. The unit should be installed in a restricted access location so that unintentional touch of the unit hot surface is blocked. The Remote Radio Head is a heat dissipating unit and so it runs at a temperature notably above the local ambient. If the temperatures of the unit become excessive the unit runs less efficiently, therefore the unit should always be mounted vertically as detailed in these instructions, in an area with unrestricted airflow/ventilation. Solar radiation can also significantly increase the temperature of the unit and so should be taken into consideration when choosing a location for the unit. In particular it is recommended that the finned surfaces should be shaded from the sun. Ideally in the Northern Hemisphere the unit should be located on a North facing wall where it is shaded from the sun; or in a location where an adjacent object or building offers similar shade. In the Southern hemisphere the unit is should ideally be located on a South facing wall. In areas where the temperature can be considered to be moderately warm, or the ambient temperature could reach temperatures of approaching 30°C (86ºF) or above and shade is not given to the unit by any of the adjacent walls or buildings then a solar shield should be fitted to the unit.

Site designer is responsible to select proper cabling and circuit protection. Also take into account any national requirements that might apply. Assumptions: • Maximum currents at cables are defined according to the IEC 60364-5-52:2009 (Table B.52.2 column 6, cable with 2 loaded wires, Installation method C) • Wire sizes according to IEC 60228. • Maximum Distance: – is calculated for the whole power chain. Power Source (BBU) to Remote RF (not taking into account possible chaining of BBU Power source → FSM/PDU → FRM) – is assumed with guaranteed/maximized BBU time, that is voltage drop in cable is limited to 6,0V. – is calculated with worst case conditions, that is the lowest operational input voltage. g Note: • Cable Short circuit current maybe limiting cable maximum length. This is depending of selected distribution Circuit Breaker. Site designer is responsible to calculate end select proper circuit protection case by case. • Installation method effects to the maximum allowed conductor current (Inside insulation, Inside conduit, surface installation, ground installation, etc.). • National variations exist and have to be taken into account by site designer. • Use of optional sales items (like FSES) might have impact to voltage drop calculations. • HW Limit is 25mm². If thicker cable is needed, then external jumpering is needed. • NSN recommended DC feeder cable type is MCCMK or MCMK shielded cable. An equivalent locally supplied DC cable might be used, it is also recommended to use shielded twisted pair cable type.

An equivalent locally supplied DC cable might be used. Make sure that both ends of the connection to a Flexi RF Module or System Module are IP65-protected. DC cable extension: • There is an additional NSN IP55 2 m DC cable in the FSEC sales package. By cutting both cables in one end and using IP55 protection to both the RF Module and System Module they can be used for extending the DC cable distance. • A long DC cable needs to be shielded and grounded. • Connection of the long DC cable and NSN IP55 cable is recommended to be done in an IP55 outdoor weather protected space, for example in Flexi External OVP box (FSEC). • The FSEC clamping range is from 19 mm to 28 mm DC cable diameters. t If the diameter of the cable is smaller than 19 mm (0.75 in.), use either self-fusing tape or heat-shrinkable tube to increase the cable diameter to 20mm- 21mm (0.79-0.83 in.) to fulfil the IP67 requirement. The distance between the expansion and the stripped part of the cable must be at least 10 cm (4 in.).

Up to four 3U modules can be fitted on either pole mounting kit, and up to three Remote Radio Heads can be fitted on one FPKA. • Up to four 3U modules can be fitted on VMPB and FPKA/FPKC. • Up to three Remote Radio Heads can be fitted on one FPKA. • Up to two 2x60 W RRHs can be installed with an FMFA on the same FPKA. Only one 2x40 W RRH can be installed with an FMFA on the same FPKA. • A 2x60 W RRH can be installed next to an FMFA on an FPKA. A 2x40 W RRH cannot be installed next to an FMFA on an FPKA. Flexi Multiradio BTS LTE Installation Site Requirements Site requirements Issue: 01A DN0951839 47 • If there is an FMFA installed on the pole mounting kit, RRH can be installed next to FMFA. • If two FMFAs are installed on a pole mounting kit, RRH can be installed next to FMFA. f Excess torsion damages the casings. In wall and pole installation, do not installmore than two modules per plinth. g Modules installed outdoors can be left non-operational for a maximum of oneweek. The fluctuation of temperature during one day can be 30°C (86°F) at the maximum. When installing modules on a pole, make sure that the pole at the BTS site is strong enough to withstand the weight of the BTS, to meet earthquake requirement Telcordia GR-63 core Zone 4, and the wind load requirement.
