Nokia FlexiHopper (Plus) installation

Caution

Never connect or disconnect the Flexbus cable when the power is on. Damage tothe equipment may result.

Before starting the installation, verify that you have the correct equipment(correct outdoor unit frequency and subband, correct antenna) and that theequipment has not been damaged during transport.

Also note the following prerequisites for installation:

. Transmission and installation have been planned.

. The far-end radio is installed or the installation space for the far-end radiohas been planned.

. If it is likely that moisture will condense in the outdoor unit, do not leave itoutdoors without power.

The following restrictions shall be considered before installing the outdoor unit:

. The weather conditions must be taken into account when installing theoutdoor unit. The maximum and minimum temperatures at the installationlocation must remain within the range given in the Technical specificationsfor Nokia FlexiHopper (Plus).

. The integrated antenna can be aligned 45 in a vertical direction and360 in a horizontal direction (fine adjustment 15).

. The mounting pole structure must be stable enough to keep the antennawithin its 3 dB beamwidth in all foreseeable wind conditions.

. Do not install the outdoor unit at a location where an unauthorised personcan have access to the antenna radiation region or to the equipment itself.

. When the outdoor unit is installed in regions where the temperature fallsbelow zero degrees Celsius during the winter, ice can accumulate oninstallation tower structures. Take precautions to avoid the breakage ofantennas due to falling ice. Suitable protection can be accomplished, forexample, by installing a metal grating above the antenna.

7 Grounding7.1 Grounding Nokia FlexiHopper (Plus)

Before you start

Caution

Ground electrostatic sensitive devices. Use an antistatic wrist strap or equivalentprotection when handling FIU 19 (E) plug-in units. Discharge of static electricitymay damage components.

A 16 mm2 grounding wire is used in grounding the outdoor unit.

Summary

To ensure safe installation conditions for both personnel and equipment, theequipment station must be grounded before installing the equipment. The purposeof protective grounding is to keep the potential of the equipment at the same levelas the potential of the surrounding ground. This prevents generation of dangerousvoltages between the equipment and the ground. Because of the high locations ofthe radio and base station equipment, equipment stations are particularlysusceptible to lightning strokes.

Ground the equipment according to rules and regulations issued by the localauthorities. Refer also to site level documentation, if applicable, and to documentInstalling DMR Radios to Base Station Sites, which is available in NOLS (NokiaOnline Services) Documentation Technical Documentation MicrowaveRadios Nokia DMR 8-15 Microwave Radio Customer Documentation.

For further information on protection against interference, refer to ITU-T K.27(Bonding configurations and earthing inside a telecommunication building) orcorresponding recommendations.
