3.5 Grounding
To protect the Nokia MetroSite EDGE Base Station from damaging over voltages
through antenna equipment, communication cables, or power supply lines,
grounding cabling must be planned and installed before installation of the base
station. To avoid interference, it is recommended that large grounding systems be
designed case-specifically.
A electrical plug with a ground connection is not sufficient for the Nokia
MetroSite EDGE Base Station. Grounding must have a fixed, non-removable
connection.
Regulations issued by local authorities must be followed when planning the
grounding 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 BTS
cabinet.
All Nokia MetroSite EDGE Base Stations are equipped with two
grounding 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 indoor
installations, the minimum cross-section of the copper conductor is 2.5
mm2 (12 AWG).
• The maximum cross-section of the grounding cable’s copper conductor is
35 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 are
exposed to the risk of lightning.
A grounding cable can be ordered from Nokia.

WARNING
3.6 Mains power
The power switch on the power supply unit (PSU) of the Nokia MetroSite
EDGE Base Station 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 to be the
disconnect device for safety and service purposes.
Follow the national legislation when working with the power supply. The
Nokia MetroSite EDGE Base Station must be permanently wired to a
disconnect device (such as a circuit breaker) in accordance with your current
local and national wiring standards.
All ground connections must be secure and non-removable.
All power cabling must meet the requirements of the appropriate national
standard.
The Nokia MetroSite EDGE Base Station has four power supply options: 230
VAC, 110 VAC, -48 VDC and +24 VDC. The permitted voltage fluctuation for
the different options is presented in Table 5.
It is recommended that the AC mains be protected with a lightning and transient
overvoltage protector (mains wire-in protector). This protection is not included in
the Nokia MetroSite EDGE Base Station.
3.6.1 Power consumption
The power consumption of the Nokia MetroSite EDGE Base Station is dependent
on the following factors:

3.6.3 Connectors, cables, and fuses for cable protection
Prefabricated mains power cables can be ordered from Nokia.
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.

Note
In general, the fuses for cable protection must be rated according to the national
electrical safety regulations.
For information on the pin configurations for the different BTS power supply
connector types, refer to Nokia MetroSite EDGE Base Station: Product
Description.
3.7 Painting the BTS cover
If desired, the BTS cover can be painted to blend into the surrounding
environment, although some dark colours with high absorptivity may be
restricted because of heat retention.
For painting the cover, Nokia recommends a primer-topcoat combination of
Beckers TD 130 primer and Beckers TH 141 surface paint. Other paints suitable
for polycarbonate surfaces may also be used.

Caution
Do not use any paints that contains alkalis, esters, ketones, or aromatic,
chlorinated, or fluorinated hydrocarbons. These chemicals may damage the cover
and paint containing them can only be used if approved by the manufacturer for
painting polycarbonate objects.
The selected paint must be UV and weather resistant, and suitable for
temperatures ranging from -40°C to +50°C (-40°F to 122°F). For environmental
conditions, refer to ETS 300 019-1-4:1992 class 4.1.
Painting the BTS cover
1. Remove the BTS cover as instructed in Nokia MetroSite EDGE Base
Station: Maintenance.
2. Before painting, detach the cable cover and remove the cable cover
support. The cover top can also be detached from the cover by unscrewing
the Torx T20 screws (see Figure 6).

3. Remove any stains and dust from the surface of the cover with an alcoholic
or acidic wash, or with water and a mild washing agent. Do not use washing
agents that contain alkalis, esters, ketones, or aromatic, chlorinated, or
fluorinated hydrocarbons.
4. Rinse with water to remove any residue of cleaning chemicals.
5. Dry the cover parts by blowing ionized air on them to remove electrostatic
charges and dust particles.
6. Place a support under the cover and the cover top so that you do not have
to touch the parts during painting.
7. Use a clamp or hook for holding the cable cover and the cable cover
support during painting. See Figure 7 for areas on which to place the clamp.

8. Spray paint over the outside surface of the cover. Spraying should be done
at 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 temperature
according to the paint manufacturer’s drying instructions.
The temperature of the drying oven must not exceed 90°C (194°F).
10. When the paint is dry, attach the cover top to the cover. Tighten the screws
to 1.6 Nm (1.18 lb ft).
