PTP 670 QUICK START GUIDEPAGE 13Ensure that the installation meets the requirements defined in thePTP 670 Series User Guide.Grounding cable installation methodsTo provide effective protection against lightning induced surges, observe these requirements: Grounding conductor runs must be as short, straight and smooth as possible, with bends and curves kept toa minimum. Grounding cables must not be installed with drip loops. All bends must have a minimum radius of 203 mm (8 in) and a minimum angle of 90°. A diagonal run ispreferable to a bend, even though it does not follow the contour or run parallel to the supporting structure. All bends, curves and connections must be routed towards the grounding electrode system, ground rod, orground bar. Grounding conductors must be securely fastened. Braided grounding conductors must not be used. Approved bonding techniques must be used for the connection of dissimilar metals.Siting ODUs and antennasODUs and external antennas are not designed to survive direct lightning strike. For this reason they must beinstalled in Zone B as defined inPTP 670 Series User Guide. Mounting in Zone A may put equipment, structuresand life at risk.Wind survival speedsEnsure that the ODU and the structure to which it is mounted can withstand the maximum wind speeds at aproposed site.Surface temperatureThe ODU enclosure may be hot to the touch when in operation.Equipment manufacturerCambium Networks Ltd, Unit B2 Linhay Business Park, Eastern Road, Ashburton, Devon, TQ13 7UP, UnitedKingdom.
