HazardsFire

How to prevent fire:

Fire

Close cable ducts and fire doors as soon as possible.

Af l i h k l h bl After completing the work, seal the cable ducts according to the regulations for the building.

Minimize the amount of flammable materials.

Avoid storing empty packaging material on the site.

Use a powder or carbon dioxide type of fire extinguisher due to the electrical nature of the equipment on the site.

Hazards Laser

Fibre-optical cables considerations: Never view the exposed end of a fiber, fiber

connector or bulkhead connector.

E th t th ti l i ff b f i i Ensure that the optical source is off before viewing or inspecting any optical port or optical connector.

Use an approved microscope when examining any part of an optical system or optical connector. Never use a magnifying glass or any other optical device.

Always consider any fiber fiber connector or bulkhead Always consider any fiber, fiber connector or bulkhead connector to have laser light present unless you have verified the opposite.

Antenna System and Feeders InstallationFeeders Installation

PS: The installation of the GSM antennas and feeders will be described in this section.The Mini-Link system installation will be described further in different section.Th th t th t t b f ll dThese are the steps that are to be followed:1- Connecting the jumpers into the X polarized antennas (2 jumpers in each antenna)(2 jumpers in each antenna).2- If there’s any mechanical down tilting on the antenna, the upper base will be calibrated to get the tilting angle.If upper tilt, the lowerbase will be calibrated.3- Lifting the antennas up to their positions on the brackets.4 P iti i th t d ti ht th f b th d4- Positioning the antennas and tighten the screws of both up and down bases in the correct direction (azimuth).5- Connecting the feeders into the jumpers (upper part)5 Connecting the feeders into the jumpers (upper part).6- Tightening the feeders to the steps and the ladders and routing them properly to the shelter.

157- Earthing the feeders and marking them.8- Connecting the feeders into the jumpers (lower part).A.HAMMOUD

Positioning the antennas

Antenna bracket

Down base

The direction or the azimuth of each antenna will be mentioned in the site binder, soa compass is used to get some reference point on the same direction of the antenna in order to put it in the exact direction.

17And then, the screws of both down and upper bases will be tightened on the antennametal support.

Site Build form exampleA.HAMMOUD

Antenna Tilting

If there’s a mechanical down tilt, the uppersupport (tilt kit) should be calibrated on the ground before fixing the antenna according to a table.If there’s a mechanical up tilt, the lower base (tilt kit) should be calibrated.

18If there’s an electrical tilt. A screw on the lower side of the antenna is manipulated to get the demanded angle.A.HAMMOUD
