Safety Precautions

WORKING ON THE BUILDING’S ROOF

During stormy weather, do not perform any mechanical assembly or antenna beaming works on the building’s roof.

The metal structure of towers/ masts is prone to lightning.

PLUGGING/ UNPLUGGING COAXIAL CONNECTORS

Never plug (or unplug) the connector of the coaxial IF cables from theoutdoor transceiver boxes (BRBs), when the respective indoor equipmentis powered on and operating.

There is risk of equipment failure and/ or electrical shock, as the IF cable carriesthe DC operating voltage (-48 V) for the outdoor transceiver.

Before plugging or unplugging the IF cable in/ from the BRB box, you must firstextract or shut down the respective interconnected indoor unit.

PROPER GROUNDING

Ensure the effectiveness of the construction of the grounding systembefore powering up the WiBAS equipment at the Base Station.

In case of inappropriate grounding system, there is risk of equipment failure and/or electrical shock.

Ensure that the outdoor grounding system measures a path resistance of < 3 Ω.

Site Prerequisites, Continued

Outdoor groundingsystem

A dedicated, low-resistance grounding system (typically < 3 Ω) is required.

A grounding point (designated GND) should be located close to the mountingposition of the BRB radio boxes.

Each BRB will be connected to this grounding point, via the suppliedgrounding cable. This will provide protection of the equipment againstharmful lightning conditions.

Coaxial cables The coaxial cables, connecting the indoor units with the outdoor BRB boxes,should be of coaxial 75-ohm type.

The maximum length of these cables depends on their quality and the

degradation that they impose to the IF signal.Typical length of IF cable is 175 m (using RG-11 low-loss coaxial cable of 8.3dB/ 100 m at 420 MHz attenuation).

NOTE Under no circumstance should the total attenuation (imposedby the IF cable itself) exceed 15 dB.

Proximity toGSM (2G / 3G)installations

GSM Cables:

The WiBAS coaxial cables must be spaced from neighboring GSM cables

and antennas for at least 30 cm.The cable must be in good condition, without any visible breakings or deterioration and properly terminated, as instructed in this manual.

Also, extra care must be taken during the cable unrolling from the bin, asaccidental twists may affect cable’s performance.

GSM Antennas:

When WiBAS and GSM equipment is to be collocated, BRB / BRA must beinstalled on the same pole / mast, below or above the neighboring GSMantennas and at a distance no less than 4 m.

If a different pole / mast is the only option, then the BRB should be installedin such a way that it is located outside the -20 dB radiation pattern of allneighboring 2G / 3G antennas, with a minimum horizontal distance of 4 m

between the pole (where the BRB / BRA is installed) and the polesaccommodating GSM antennas.
