3.1Pre-Installation
Pleaseread thefollowingguidelinesconcerning installationandconnectionbeforeinstallingthe ipLDK-60 System.Be
suretocomplywithapplicablelocalregulations.
3.1.1 Safety InstallationInstructions
Wheninstallingthetelephonewiring,basicsafetyprecautionsshouldalwaysbefollowedtoreducetherisk offire,
electricshock andpersonal injury, including thefollowing:
§Neverinstallthe telephonewiring during alightning storm.
§Neverinstallthe telephonejackinwetlocationsunlessthejackisspecificallydesigned forwet
locations.
§Nevertouchun-insulatedtelephonewiresorterminalsunlessthe telephonelinehasbeen
disconnected atthe networkinterface.
§Usecaution wheninstallingormodifyingtelephonelines.
§Anti-staticprecautionsshouldbetakenduring installation.
3.1.2 Installation precautions
The ipLDK-60Systemisdesigned forwall mountingorafree–standingrack.Avoidinstalling inthe following places:
§Indirectsunlight andhot,cold,orhumid places.Temperaturerange= 0to40oC.
§Placeswhereshocksorvibrationsarefrequent orstrong.
§Dustyplaces, orplaceswherewateroroilmaycomeintocontact withthe System.
§Nearhigh-frequency generatingdevicessuchassewingmachinesorelectricwelders.
§Onornearcomputers, faxmachines,orotherofficeequipment, aswellasmicrowaveovensor
airconditioners.
§Donotobstructtheopeningsonthetop ofthe ipLDK-60 System.
§Donotstackuptheoptional serviceboards.
3.1.3 Wiring Precautions
Besuretofollowtheseprecautionswhenwiring:
§Donotwirethe telephonecableinparallelwithanACpowersource,suchasacomputer,fax
machine,etc.If thecablesarerunnearthosewire, shieldthecableswithmetal tubing oruse
shieldedcablesandgroundtheshields.
§If the cablesarerunonthefloor,useprotectorstopreventthewiresfrombeing stepped on.
Avoidwiringundercarpets.
§Avoidusingthesamepowersupplyoutletforcomputers, faxmachine,andotheroffice
equipment toavoidinductionnoiseinterruption whenusingthe ipLDK-60 nearothermachines.
§ThepowerandbatteryswitchesmustbeOFF duringwiring.Afterwiring iscompleted,thepower
switchmaybe turnedON.
§Incorrect wiring maycausethe ipLDK-60Systemtooperateimproperly.
§If anextensiondoesnot operateproperly, disconnect thetelephonefromtheextensionlineand
thenre-connect,orturnthe SystempowerOFFandthenONagain.
