This is to ensure that the mounting is strong enough to bearthe weight of the BTS (maximum 40 kg / 88.2 lb) in its operating environment.Pole mounting kitAn optional pole mounting kit is required for pole installations. This kit is orderedseparately if required. The pole diameter can be between 60 and 300 mm (2.36and 11.81 in.). Refer to Nokia MetroSite EDGE Base Station: Installation fordetailed information on pole mounting of the BTS.Anchor screwsAnchor screws are used for attaching the Nokia MetroSite EDGE Base Station tothe wall. These screws are not included in the delivery.The anchor screws must be M6 size, stainless steel, and with the minimumbreaking strength (Rm) of 800 N/mm2. An appropriate mounting counterpart forthe anchor screw (such as an anchor plug) must be selected according to the screwand the mounting base material. If the anchor screws are of a type other thanmetric, they must be selected to meet the strength requirements mentioned above.Wind loadFor pole mounting, a pole strong enough to withstand stormy conditions must beselected.

Installation requirementsDN9913471 © Nokia Corporation Draft 27 (44)Issue 3-0 en Nokia Proprietary and ConfidentialNoteNote3.5 GroundingTo protect the Nokia MetroSite EDGE Base Station from damaging over voltagesthrough antenna equipment, communication cables, or power supply lines,grounding cabling must be planned and installed before installation of the basestation. To avoid interference, it is recommended that large grounding systems bedesigned case-specifically.A electrical plug with a ground connection is not sufficient for the NokiaMetroSite EDGE Base Station. Grounding must have a fixed, non-removableconnection.Regulations issued by local authorities must be followed when planning thegrounding of a BTS site!In general, grounding is planned according to the following requirements:• The grounding cable is connected to the grounding point inside the BTScabinet.All Nokia MetroSite EDGE Base Stations are equipped with twogrounding point alternatives: a cable clamp location and a grounding stud.Selection is made in accordance with local regulations.• The minimum cross-section of the grounding cable’s copper (Cu)conductor is 16 mm2 (5 AWG) in outdoor installations. In indoorinstallations, the minimum cross-section of the copper conductor is 2.5mm2 (12 AWG).• The maximum cross-section of the grounding cable’s copper conductor is35 mm2 (2 AWG).• The maximum value for ground resistance is 10 mΩ.• The grounding cable must be connected to a main grounding bus bar.• The routing of the grounding cable must be as direct as possible.Unnecessary loops should be avoided.• The external antenna feeders must also be grounded if the antennas areexposed to the risk of lightning.A grounding cable can be ordered from Nokia.
