The Nokia FlexiHopper (Plus) C2.3 product documentation covers both NokiaFlexiHopper and Nokia FlexiHopper Plus, which are henceforth referred to asNokia FlexiHopper and Nokia FlexiHopper Plus, respectively.
When the presented information refers to both Nokia FlexiHopper and NokiaFlexiHopper Plus, the marking Nokia FlexiHopper (Plus) is used.
1.1.1 Precautions
The radiation emitted by the antenna is low-power radiation and does not exceedthe safety regulations. If the radio is operated without the antenna, the safety limitis exceeded near the waveguide openings.
Warning
Do not look into an open waveguide while the equipment is operating, asdamage to the eye may result. The safety distance is 25 cm (0.1 mW/cm2).

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.

3.5 Installing a separate antenna
Before you start
It is possible to use an antenna that is separate from the outdoor unit. The outdoorunit and the antenna are connected by a flexible waveguide or an ellipticalwaveguide.
Large antennas (larger than 60cm) are mounted on the antenna manufacturersown alignment units. Small antennas (20, 30, and 60 cm) are mounted on theNokia alignment unit.
The outdoor unit is mounted on its own mounting unit (or alignment unit) and thewaveguide is connected to it with an adapter. The mounting unit is a simplifiedversion of the Nokia alignment unit.
The antenna feeder has threaded holes for the installation of the waveguide withscrews.
When used with a separate antenna, the Nokia FlexiHopper (Plus) outdoor unit isalways installed with the handle facing down.
Note
Always install the waveguide adapter with the guide hole facing up and the waterhole facing down.
Polarisation can be changed by turning the antenna feeder. For instructions, seeChanging polarisation for antennas.
Check the coarse alignment before installing the antenna.

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.
