selecting suitable antennas.
Note
The antenna (ANT) connector of the FP310RAM-X must always connected to
antenna or be terminated in matched (50

) loads.
2-3.2.1 FP310RAM-X-to-Antenna Cabling
The maximum distance between the FP310RAM-X and its antenna is limited by cable signal loss.
Generally, the total signal loss between the antenna and the FP310RAM-X must be less than 3 dB. Any
losses on antenna patch panels must also be taken into consideration.
Cable routes should be carefully planned, to ensure they follow the shortest path yet are far from sources
of strong electrical interference such as electrical motors, air conditioning equipment, two-way radios, etc.
Make sure that cables are physically protected, for example, by routing them within cable ducts: sharp
bends, distortion of the cable outer shield, etc., may increase the attenuation by an unpredictable amount.
2-3.3 Communication Cables
The cables connecting the FP310RAM-X host port must be shielded. Communication-grade cables
consisting of twisted pairs with external shield should be used, and the shield must be grounded at one
end. Cables should be run through grounded conduits, to minimize external interference.
2-3.4 Grounding and Lightning Protection Requirements
All the FP310RAM-Xs, antenna, mounting pole, cabinet, cable conduits and cables must be properly
grounded in accordance with the applicable regulations, to prevent injury to personnel or damage to
equipment from lightning or other high voltage sources.
Ground bonding points must be free of paint and corrosion. Star washers should be placed on screws to
ensure good electrical contact.
For installations where a complete bonded ground connection is not possible for the entire antenna-to-
FP310RAM-X cabling, a separate lightning arrester must be installed at a point near the RF connection to
the FP310RAM-X cabinet.
2-4. Installation Procedure
2-4.1 Tools and Materials
Huber + Suhner 74Z-0-0-21 - SMA wrench with fixed torque.
Torque screwdriver to close the screws used to mount the FP310RAM-X unit to the cabinet.
2-4.2 Preparation for Installation
Refer to the site installation plan, and make sure all the required components, cables, and accessories are
available.
Identify the prescribed physical location of each system component, and find the grounding points.
Before installing any item (FP310RAM-X, cabinet, mounting accessory, antenna, cable conduit, etc.),
thoroughly clean the surface on which it will be mounted.
