System Requirements for Installation and Operation

4.4 Requirements for wall and pole installation

Qualified personnel must inspect the installation wall and/or pole or other vertical
support before mounting the MU, RU and mounting rack. The installation wall or
pole must be strong enough to bear the weight of each unit.

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). These dimensions are applicable to
the MU. The RU can be mounted on a thinner pole.

Anchor screws

The anchor “Fishers” screws are used for attaching the MU and mounting frame
and RU with the mounting rack to the wall.

The MU anchor screws must be M6 size, stainless steel with the minimum
breaking strength (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

the mounting base material. If the anchor screws are of other standard than the
metric standard, they must be selected so that they meet the requirement set to the
metric standard screws mentioned above.

4.5 Grounding

To protect the MU from damaging overvoltages through communication cables,
or power supply lines, grounding cabling must be planned and installed before the
installation of the MU. To avoid interference, it is recommended that large
grounding systems be designed case-specifically.

A power plug with protective ground connection is not sufficient for the MU.
Grounding must have a fixed, non-removable connection.

Note

Regulations issued by local authorities/legislation must be followed when

planning the grounding of a site!

In general, grounding is planned as follows:

• The grounding cable is connected with screws or with a nut to the
grounding point of the MU. The grounding cable must be fitted with an
appropriate lug.

• The minimum cross-section of the copper grounding conductor is 2.5 mm2

• The maximum cross-section of the copper grounding conductor is 35 mm

• The maximum value of ground resistance is 10 mΩ

2

• The ground cable must be connected to a main grounding busbar

4.7 Painting the Main Unit cover

If desired, the MU cover can be painted to make it better blend into the
surrounding environment. Some dark colours with higher absorptivity may be
restricted.

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.

Caution

Do not use any paint that contains alkalis, esters, ketones, aromatic, chlorinated,

or fluorinated hydrocarbons, since these may damage the cover. Paint containing
these chemicals 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.

To paint the Nokia InLite cover:

1. Remove the MU cover as instructed.

2. Before painting, detach the cable cover and the cable cover support from

each other to prevent them from sticking to each other by paint and to
ensure that paint is applied evenly. The cover top can also be detached from
the cover by unscrewing the Torx T20 screws (see Figure ).

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 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 for areas on which to place the clamp.
