SECTION2. KSUINSTALLATION
2.1Pre-Installation
Pleaseread thefollowing guidelinesconcerninginstallationandconnection beforeinstalling theIPLDK-20 System.
Besurealsotocomplywithapplicablelocalregulations.
2.1.1Safetyinstallation instructions
Wheninstalling thetelephone wiring,basicsafetyprecautionsshouldalways be followed toreducethe risk offire,
electricshock andpersonal injury, includingthefollowing:
•Neverinstallthe telephonewiring during alightning storm.
•Neverinstallthe telephonejackinwetlocationsunlessthejackisspecificallydesigned forwetlocations.
•Nevertouchuninsulatedtelephonewiresorterminalsunlessthetelephone line hasbeendisconnected atthe
networkinterface.
•Usecaution wheninstallingormodifyingtelephonelines.
•Anti-staticprecautionsshouldbetaken during installation.
2.1.2Installationprecautions
The IPLDK-20Systemisdesigned forwallmountingorafree-standingrack.Avoid installinginthefollowingplaces.
•Indirectsunlight andhot,cold,orhumid places.Temperaturerange: 0to40
•Placeswhereshocksorvibrationsarefrequent orstrong.
•Dustyplaces, orplaceswherewateroroilmaycomeintocontact withthe system.
•Nearhigh-frequency generatingdevicessuchassewingmachinesorelectricwelders.
•Onornearcomputers, faxmachines,orotherofficeequipment, aswellasmicrowaveovensorairconditioners.
•Donotobstructtheareaaroundthe IPLDK-20 System(forreasonsofmaintenanceandinspection)
•DonotblocktheopeningsonthetopoftheIPLDK-20 System.
•Donotstackuptheoptional serviceboards.
2.1.3Wiring precautions
Besuretofollowtheseprecautionswhenwiring.
•Donotwirethetelephone cableinparallel withanACpowersource,suchasacomputer,faxmachine,etc.Ifthe
cablesarerun nearthosewires,shieldthecableswithmetal tubing oruseshieldedcablesand groundtheshields.
•If thecablesarerun onthe floor,useprotectorstopreventthe wiresfrombeing stepped on.Avoidwiringunder
carpets.
•Avoidusingthesamepowersupplyoutletforcomputers,faxmachines,andotherofficeequipmenttoavoid
inductionnoiseinterruptionwhen using the IPLDK-20nearothermachines.
•Thepowerand batteryswitchesoftheIP LDK-20 Systemmustbe OFFduringwiring.Afterthewiringiscompleted,
the powerswitchmaybeturned ON.
•Incorrect wiring maycausethe IPLDK-20Systemtooperateimproperly.
•If anextension doesnotoperateproperly,disconnectthetelephone fromthe extensionline andthenre-connect,
orturnthepowerof the IPLDK-20SystemOFF andONagain.
