Installation requirements 3 Installation requirements This chapter specifies the preparatory requirements for the installation of the Nokia MetroSite GSM BTS. 3.1 Checking the site The cabinet installation phase requires that the site be properly surveyed and prepared, and that all required external services are correctly installed. The site survey must identify any special requirements for the installation. The site must meet the following requirements before the installation can be started: 3.2 1.
Nokia MetroSite GSM Base Station, Requirements for Installation and Operation 3.2.1 Nokia MetroSite BTS dimensions and weight Figure 1 presents the dimensions of the Nokia MetroSite GSM BTS. 870 mm (34.25 in) 114 mm (4.49 in) 310 mm (12.20 in) Figure 1. 215 mm (8.46 in) Dimensions of Nokia MetroSite BTS cabinet The Nokia MetroSite GSM BTS with four TRXs weighs approximately 40 kg (88.4 lb). The mounting rack weighs approximately 2 kg (4.4 lb).

Clearances around Nokia MetroSite BTS The packing cardboard provides a template for defining the clearances around the BTS and for marking the drilling holes needed for wall mounting.
Nokia MetroSite GSM Base Station, Requirements for Installation and Operation • For removing units on the right-hand side of the BTS • For removing the cover above the BTS • For hanging the cover on the left-hand side of the BTS • For cables and for cooling under the BTS Note In order to hang the cover on the side of the cabinet during installation and maintenance, a clearance of 250 mm (10 in) is required.
Installation requirements A) Vertical mounting Figure 3. B) Horizontal mounting Mounting of Nokia MetroSite BTS Note If there is a risk that lumps of snow or pieces of ice can fall onto the BTS (from the antenna or microwave radio pole, for example), an effectual roof must be mounted to shield the BTS.
Nokia MetroSite GSM Base Station, Requirements for Installation and Operation 3.4 Requirements for wall and pole installation Qualified personnel must inspect the installation wall and/or pole before mounting the BTS. Ensure that the installation wall or pole is strong enough to bear 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 is between 60 and 300 mm (2.36 and 11.81 in).
Installation requirements A power plug with protective ground connection is not sufficient for Nokia MetroSite BTS. Grounding must have a fixed, non-removable connection.
Nokia MetroSite GSM Base Station, Requirements for Installation and Operation 3.6 Mains power WARNING The power switch on the power supply unit of the Nokia MetroSite GSM BTS does not disconnect it from the power network (AC or DC), but leaves it in a stand-by mode. The switch has two positions: ON and stand-by. A separate main switch on the site is considered a disconnect device for safety and service purposes. Follow the national legislation when working with the power supply.
Installation requirements • BTS configuration • Ambient temperature • Direction of the temperature change The power consumption is higher when the ambient temperature is decreasing and the heating power of the BTS is increasing. When the ambient temperature is rising, the heating power is reducing. Consequently, the power consumption of the Nokia MetroSite GSM BTS in a given temperature varies according to the direction of temperature change.
Nokia MetroSite GSM Base Station, Requirements for Installation and Operation 3.6.2 Acoustic sound power The fan unit of the Nokia MetroSite GSM BTS generates acoustic noise. The level of acoustic sound power is dependent on the following factors: • Ambient temperature • Rate of the temperature change • Ouput power The acoustic sound power level is higher when the ambient temperature is changing rapidly. Refer to Figure 5 for the range of acoustic sound power level in different ambient temperatures.
Installation requirements 3.6.3 Connectors, cables and fuses for cable protection Note Prefabricated mains power cables can be ordered from Nokia. Note If you use the prefabricated mains power cable supplied by Nokia, make sure that the power distribution box (mains power supply) is located no further than 10 metres from the BTS’s power supply unit. Table 6 presents the requirements for power supply cables and the recommended mains fuses. Table 6.
Nokia MetroSite GSM Base Station, Requirements for Installation and Operation 3.7 Painting the BTS cover If desired, the BTS cover can be painted to make it better blend into the surrounding environment. Nokia recommends that for painting the cover a primer-topcoat combination of Beckers TD 130 primer (for priming) and Beckers TH 141 paint (for surface painting) be used. Other paints suitable for polycarbonate surfaces may also be used.
Installation requirements Figure 6. Removing the cover top 3. Remove stains and dust from the surface of the cover with an alcoholic or acidic wash, or wipe it clean with a piece of cloth moistened with water and mild 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.
Nokia MetroSite GSM Base Station, Requirements for Installation and Operation Figure 7. 8. Areas used for holding the cable cover parts during painting Spray paint over the outside surface of the cover. Spraying should be done at room temperature with relative air humidity of 50-65%. Note 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 temperature according to the paint manufacturer’s drying instructions.
