Nokia MetroSite GSM Base Station, Requirements for Installation and Operation22 (38) © Nokia Networks Oy Internal Copy DN9913471Issue 1 en DRAFT 2 Draft3.4 Requirements for wall and pole installationQualified personnel must inspect the installation wall and/or pole beforemounting the BTS. Ensure that the installation wall or pole is strong enough tobear the weight of the BTS (max. 40 kg / 88.4 lb) in any condition.The optional pole mounting kit can be used when the installation pole diameter isbetween 60 and 300 mm (2.36 and 11.81 in).Anchor screwsThe anchor screws are used for attaching the Nokia MetroSite GSM BTS to thewall. These screws are not included in the delivery.The anchor screws must be M6 size, stainless steel with the minimum breakingstrength (Rm) of 800 N/mm2. An appropriate counterpart for the anchor screw(for example, an anchor plug) must be selected according to the screw and themounting base material. If the anchor screws are of other standard than the metricstandard, they must be selected so that they meet the requirement set to the metricstandard screws mentioned above.Wind loadFor pole mounting a pole must be selected which does not break off even instormy winds. Table 4 shows the load imposed on the pole (with a BTS attachedto it) in two wind velocities.3.5 GroundingTo protect the Nokia MetroSite GSM BTS from damaging overvoltages throughantenna equipment, communication cables, or power supply lines, groundingcabling must be planned and installed before the installation of the base station.To avoid interference, it is recommended that large grounding systems bedesigned case-specifically.Table 4.

Installation requirementsDN9913471 © Nokia Networks Oy Internal Copy 23 (38)Issue 1 en DRAFT 2 DraftNoteNoteA power plug with protective ground connection is not sufficient for NokiaMetroSite BTS. Grounding must have a fixed, non-removable connection.Regulations issued by local authorities/legislation must be followed whenplanning the grounding of a BTS site!In general, grounding is planned as presented in the following:• The grounding cable is connected with screws or with a nut to thegrounding point of the Nokia MetroSite GSM BTS, depending on which ofthe two grounding point alternatives is chosen. All Nokia MetroSite GSMBTSs are equipped with two grounding point alternatives: a cable clampand a grounding stud. The selection between the two alternatives must bedone according to local regulations. When grounding stud is used, thegrounding cable must be fitted with an appropriate lug.• The minimum cross-section of the copper (Cu) grounding conductor is 16mm2 (5 AWG) in outdoor installations. In indoor installations, theminimum cross-section of the copper grounding conductor is 2.5 mm2(12AWG)• The maximum cross-section of the copper grounding conductor is 35 mm2(2 AWG)• The maximum value of ground resistance is 10 Ω• The ground cable must be connected to a main grounding busbar• The routing of the ground cable must be as direct as possible. Unnecessaryloops should be avoided• The external antenna feeders must also be grounded, if the antennas areexposed to lightningA grounding cable can be ordered from Nokia.
Nokia MetroSite GSM Base Station, Requirements for Installation and Operation24 (38) © Nokia Networks Oy Internal Copy DN9913471Issue 1 en DRAFT 2 DraftWARNING3.6 Mains powerThe power switch on the power supply unit of the Nokia MetroSite GSMBTS does not disconnect it from the power network (AC or DC), but leavesit in a stand-by mode. The switch has two positions: ON and stand-by. Aseparate main switch on the site is considered a disconnect device for safetyand service purposes.Follow the national legislation when working with the power supply. TheNokia MetroSite GSM BTS must be permanently wired to a disconnectdevice (e.g. circuit breaker) in accordance with current local and nationalwiring standards.All ground connections must be secure and non-removable.All power cabling must meet the requirements of the appropriate nationalstandard.The Nokia MetroSite GSM BTS has three power supply options: 230 VAC, 110VAC and 36/48/60 VDC. The permitted voltage fluctuation for the differentoptions is presented in Table 5.It is recommended that the AC mains be protected with a lightning and transientovervoltage protector (mains wire-in protector). This protection is not included inthe Nokia MetroSite GSM BTS.3.6.1 Power consumptionThe power consumption of the Nokia MetroSite GSM BTS is dependent on thefollowing factors:Table 5.

Nokia MetroSite GSM Base Station, Requirements for Installation and Operation28 (38) © Nokia Networks Oy Internal Copy DN9913471Issue 1 en DRAFT 2 DraftCaution3.7 Painting the BTS coverIf desired, the BTS cover can be painted to make it better blend into thesurrounding environment.Nokia recommends that for painting the cover a primer-topcoat combination ofBeckers TD 130 primer (for priming) and Beckers TH 141 paint (for surfacepainting) be used. Other paints suitable for polycarbonate surfaces may also beused.Do not use any paint that contains alkalis, esters, ketones, aromatic, chlorinated,or fluorinated hydrocarbons, since these may damage the cover. Paint containingthese chemicals can only be used if approved by the manufacturer for paintingpolycarbonate objects.The selected paint must be UV and weather-resistant and suitable fortemperatures ranging from -40 °Cto+50°C (-40 °F to 122 °F). For environmentalconditions, refer to ETS 300 019-1-4:1992 class 4.1.To paint the BTS cover:1. Remove the BTS cover as instructed in Nokia MetroSite GSM BTS:Maintenance.2. Before painting, detach the cable cover and the cable cover support fromeach other to prevent them from stucking to each other by paint and toensure that paint is applied evenly. The cover top can also be detached fromthe cover by unscrewing the Torx T20 screws (see Figure 6).
Installation requirementsDN9913471 © Nokia Networks Oy Internal Copy 29 (38)Issue 1 en DRAFT 2 DraftFigure 6. Removing the cover top3. Remove stains and dust from the surface of the cover with an alcoholic oracidic wash, or wipe it clean with a piece of cloth moistened with water andmild washing agent. Do not use washing agents that contain alkalis,aromatic, chlorinated, or fluorinated hydrocarbons, esters or ketones.4. Rinse with water to remove residuals of cleaning chemicals.5. Dry the cover parts by blowing ionized air on them to remove electrostaticcharges and dust particles.6. Place a support under the cover and the cover top so that you do not haveto touch the parts during painting.7. Use a clamp or hook for holding the cable cover and the cable coversupport during painting. See Figure 7 for areas on which to place the clamp.

Areas used for holding the cable cover parts during painting8. Spray paint over the outside surface of the cover. Spraying should be doneat room temperature with relative air humidity of 50-65%.The maximum thickness of the paint should not exceed 100 µm.9. Dry the parts either in an oven or let the paint dry at room temperatureaccording to the paint manufacturer’s drying instructions.The temperature of the drying oven must not exceed 90 °C (194 °F).10. After the paint is dry, attach the cover top to the cover. Tighten the screwsto 1.6 Nm (1.18 ft-lb).
