Install the Prism Remote Unit
3 Connectalightningsurgesuppressortotheantennaport;torqueto8±1in-lbstoensurefull
connection.
NOTE: Lightening surge suppressor(s) ship with every RF Module. If the RF modules are populated in
the PRU from the factory, the lightening surge suppressors are in the Prism shipping crate. If
the RF Module is shipped individually, the lightening surge suppressor is shipped within the
RF Module shipping container.
4 IfthePRUhasaaDual20WSMR800/PCS1900RFModule(FWP-441T841MOD),youmustinstall
aFlexWaveNotchFilter(FWP-SPRINTFILTER)betweenthePRUandtheantennatoprovide
protectionfromspuriousemissionsinthePublicSafetybandbelow861.35MHzandtheCellular
bandabove869.5MHz.ForinformationonhowtoinstallaNotchFilter,goto"FlexWaveNotchFilter
(FWP-SPRINTFILTER)”onpage108.
5 Ensurethatthechassisgroundwireisinstalledcorrectly(see"GroundthePRUChassis”on
page52).Formaximumprotection,thesystemgroundwiremustbeattachedtoalowimpedance
groundsystem.
6 RoutethecoaxialantennacablefromtheantennatotheundersideofthePRU.
7 CuttheantennacabletotherequiredlengthandterminatewithanN-typemaleconnector.
8 Connecttheantennacabletothelightningsurgesuppressorortotheantennaport;apply15in-lbs
(1.7Nm)oftorque.
CAUTION! The antenna cable connections must be weather proofed (sealed) for outdoor installations.
9 RepeattheStep2throughStep8fortheremainingantennacables.
CONNECT THE POWER WIRING
ThePRUsupportsbothACandDCpower.Followthestepsappropriatetoyoursystemconfiguration:
• "Option1:ConnecttheACPowerWiring”onpage70
• "Option2:ConnecttheDCPowerWiring”onpage73.
Option 1: Connect the AC Power Wiring
A15-foot,3-wirecablewithconnectorsisprovidedfortheACpowerconnections.Theconnectorend
ofthecableconnectstotheACpowerportlocatedonthebottomoftheunit.Thestubendofthecable
mustberoutedtoanexternaljunctionbox(notprovided)forpermanentconnectiontotheACpower
systemwiring.IfthecablemustbeterminatedwithaplugtoconnecttotheACadapter,theplugmust
beprovidedbytheinstaller.
TheACpowersourcemustsupplybetween100and240Vac,50or60Hz,single-phasepowerthrough
acircuitbreakerorfuse.TheACpowercableprovidesthreewireleadsforline,neutral,andground
connections.Thepowercableisratedforindoororoutdooruseandmustnotbeplacedwithinelectrical
conduitasthiswillimpedethecoolingofthecableduringusage.Theelectricaljunctionboxandany
conduit,wire,andfittingsrequiredmustbeprovidedbytheinstaller.
CAUTION! Use extreme caution when working with high voltage AC power. Ensure all power is
disconnected before working on power circuits.
