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76
• "Option2:ConnecttheD
CPowerWiring”onpage79.
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c
ircuit
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 w
orking with high voltage AC power. Ensure all power is disconnected
before working on power circuits.
NOTE: All electrical work must comply with local codes and requirements. A locally licensed electrical
contractor is best qualified to perform this work. For additional information, consult with the
CommScope Technical Support for Wireless Products team (see "DCCSGlobalTechnicalSupport”on
page124).
Usethefollowingprocedureto
installtheACpowerwiring:
1 Usetheinformationin"DeterminetheCircuitBreakerorFuseforthe
PRU”onpage72toensurethatthecorrectcircuitbreak
erorfuse
requiredforthisinstallationisinstalledi
nthecircuitbreakerpanel.
2 Locate
theACpowercablethatisprovidedseparatelywiththePRU.
3 Routethe
powercablebetweentheACpowerport,locatedonthe
undersideofthePRUandthenearestACpowerjunctionboxasshown
inthegraphictotheright.Itmaybenecessarytoinstallanewjunction
boxifanexistingjunctionboxisnotavailable.
4 S
ecurethecablebetweentheACpowerportandtheACpowerjunction
boxperlocalpractice.Leavesufficientslackinthecabletoallowittobe
easilyconnectedanddisconnectedfromtheACpowerport.
NOTE: 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 cable run distance to the AC power
source must not exceed 100 feet.
