Installation Guidelines     2-2   2-2.3  Mechanical Data Figure ‎2-2 provides mechanical data for planning the installation of an FP310RAM-X unit.  Figure ‎2-2. FP310RAM-X Mechanical Data 2-3.  Installation Guidelines The FP310RAM-X is intended for installation in protected cabinets that prevent direct exposure to sun radiation, rain, dust and dirt. It does not require forced air cooling. The unit does not have any surge protection units inside. 2-3.1  Power Requirements The FP310RAM-X operates on 9 to 30 VDC (nominal operation at 12Vdc), at an average power drain of 0.1W with instantaneous peak power of 0.3W. A suitable power source must be provided as part of the installation.  The FP310RAM-X does not have an ON/OFF power switch, and will start operating as soon as power is connected. Therefore, it is recommended to install a circuit breaker, which will also serve as an ON/OFF switch, to protect the supply line of each FP310RAM-X. 2-3.2  Antenna The type of  antenna  to  be used  with  the  FP310RAM-X  is generally  determined by the  FP310RAM-X application and communication zone requirements. The positioning of the antenna must be carefully set to achieve  the  required  communication  zone  pattern.  Contact  Telematics  Wireless  if  you  need  help  in
Installation Procedure     2-3   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.
