Safety Precautions

Adheretothefollowingsafetyprecautionswheneveranytypeofconnectionismadetothemodule:
lConnectthegreensafety(earth)groundfirstbeforemakinganyotherconnections.
lWhenconnectingtoelectriccircuitsorpulse-initiatingequipment,opentheirrelatedbreakers.Donotmake
connectionstolivepowerlines.
lMakeconnectionstothemodulefirst;thenconnecttothecircuittobemonitored.
lRoutepowerwiresinasafemannerinaccordancewithgoodpracticeandlocalcodes.
lWearproperpersonalprotectiveequipmentincludingsafetyglassesandinsulatedgloveswhenmakingcon-
nectionstopowercircuits.
lEnsurehands,shoes,andfloorsaredrybeforemakinganyconnectiontoapowerline.
lMakesuretheunitisturnedOFFbeforemakingconnectiontoterminals.Makesureallcircuitsarede-ener-
gizedbeforemakingconnections.
lBeforeeachuse,inspectallcablesforbreaksorcracksintheinsulation.Replaceimmediatelyifdefective.

Mounting Procedures
Themechanicalinstallationgreatlyaffectstheoperation,safety,andappearanceofthesystem.Informationis
providedtomechanicallyinstalltheunitsuchascut-outsizes,mountingprocedures,andotherrecommendations
forthepropermechanicalinstallationoftheunit.XLE/XLTproductscanbemountedthroughapaneloronDINrail.
Oncethepaneldesignhasbeencompletedusingthecriteriaandsuggestionsinthefollowingsections,usethefol-
lowingstepstopanelmounttheXLE/XLT.
1. RemoveallconnectorsfromtheXLE/XLTunit.
2. PresstheDINrailclipuptomakepassingtheunitthroughthecutouteasier.
3. Makesurethegasketisinstalle`dontheXLE/XLTandisfreefromdustanddebris.Checkthatthecornersof
thegasketaresecure.
4. Passtheunitthroughthepanel.
5. Inserttheeachofthefour(4)mountingclipsintotheslotsintheXLE/XLTcase.Oneclipshouldbeinstalled
oneachcorner.Lightlytighteneachscrewsotheclipisheldinplace.
6. Tightenthescrewsontheclipssuchthatthegasketiscompressedagainstthepanel.Recommendedtorque
is7-10in-lbs[0.8-1.13Nm]).

Mounting Procedures (Installed on DIN Rail)

TheXLE/XLTisdesignedtoclipontostandard35mmDINrail.Ifyourinstallationrequiresliquidordustprotection,
makesuretheXLE/XLTisplacedinanappropriatesealedpanelwhenmountingonDINrail.Usethefollowing
stepstomounttheXLE/XLTonDINrail.
1. MovetheDINrailcliptothelowerposition.
2. Clipthe“TopClips”onthetopoftheDINrail.
3. PresstheunitintoplaceandpresstheDINrailclipup.Asmallflat-headscrewdrivercanbeusedintheslot
oftheDINrailclipifclearanceisanissue.

NOTE:TheDINrailconnectiondoesnotprovideanearthground.Refertothe"ElectricalInstallation"onpage21
forpropergroundinginformation.


Mounting Orientation

NOTE: For panel or DIN rail mounting–Theorientationshownaboveprovidesoptimumlegibilityofthescreen
andeaseofuseofthekeypad.

CAUTION: For DIN rail mounting–TopreventtheunitfromslippingofftheDINrail,doNOTinstalltheunitonits
sideasshown.BesuretheDINrailisinthehorizontalposition.

XLE/XLTmaybeinstalled.Iftheopeningistoolarge,watermayleakintotheenclosure,potentiallydam-
agingtheunit.Iftheopeningistoosmall,theOCSmaynotfitthroughtheholewithoutdamage.
3. Removeanyburrsandorsharpedgesandensurethepanelisnotwarpedinthecuttingprocess.
4. RemoveallRemovableTerminalsfromtheXLE/XLT.InserttheXLE/XLTthroughthepanelcutout(fromthe
front).ThegasketmustbebetweenthehostpanelandtheXLE/XLT.
5. Installandtightenthefourmountingclips(providedinthebox)untilthegasketformsatightseal(NOTE:Max
torque0.8to1.13Nm,7-10in-lbs).
6. ReinstalltheXLE/XLTI/ORemovableTerminalBlocks.Connectcommunicationscablestotheserialport,

Factors Affecting Panel Layout Design and Clearances
WARNING:Itisimportanttofollowtherequirementsofthepanelmanufactureandtofollowallapplicableelectrical
codesandstandards.
Thedesignerofapanellayoutmustassesstherequirementsofaparticularsystemandtoconsiderthefollowing
designfactors.

Clearance / Adequate Space
Installdevicestoallowsufficientclearancetoopenandclosethepaneldoor.
Minimum Clearance Requirements for Panel Box and Door
MinimumDistancebetweenbaseofdeviceandsidesofcabinet 2”(50.80mm)
MinimumDistancebetweenbaseofdeviceandwiringducts 1.5”(38.10mm)
If more than one device installed in panel box (or on door):
MinimumDistancebetweenbasesofeachdevice
4”(101.60mm)betweenbasesofeach
device
When door is closed:
Minimumdistancebetweendeviceandcloseddoor
(BesuretoallowenoughdepthfortheOCS.)

WARNING:Besuremeetthegroundrequirementsofthepanelmanufactuerandalsomeetapplicableelectrical
codesandstandards.

nPanel Box:Thepanelboxmustbeproperlyconnectedtoearthgroundtoprovideagoodcommonground
reference.
nPanel Door:Tiealowimpedancegroundstrapbetweenthepanelboxandthepaneldoortoensurethat
theyhavethesamegroundreference.


Temperature / Ventilation
Ensurethatthepanellayoutdesignallowsforadequateventilationandmaintainsthespecifiedambienttem-
peraturerange.Considertheimpactonthedesignofthepanellayoutifoperatingattheextremeendsoftheambi-
enttemperaturerange.Forexample,ifitisdeterminedthatacoolingdeviceisrequired,allowadequatespaceand
clearancesforthedeviceinthepanelboxoronthepaneldoor.


Noise
Considertheimpactonthepanellayoutdesignandclearancerequirementsifnoisesuppressiondevicesare
needed.BesuretomaintainanadequatedistancebetweentheXLE/XLTandnoisydevicessuchasrelays,motor
starters,etc.


Shock and Vibration
TheXLE/XLThasbeendesignedtooperateintypicalindustrialenvironmentsthatmayinflictsomeshockandvibra-
tionontheunit.Forapplicationsthatmayinflictexcessiveshockandvibrationpleaseuseproperdampeningtech-
niquesorrelocatetheXLE/XLTtoalocationthatminimizesshockand/orvibration.

Panel Layout Design and Clearance Checklist
Thefollowinglistprovideshighlightsofpanellayoutdesignfactors:
nMeetstheelectricalcodeandapplicablestandardsforpropergrounding,etc.?
nMeetsthepanelmanufacturer’srequirementsforgrounding,etc.?
nIsthepanelboxproperlyconnectedtoearthground?Isthepaneldoorproperlygrounded?Hastheappro-
priateprocedurebeenfollowedtoproperlygroundthedevicesinthepanelboxandonthepaneldoor?
nAreminimumclearancerequirementsmet?Canthepaneldoorbeeasilyopenedandclosed?Isthere
adequatespacebetweendevicebasesaswellasthesidesofthepanelandwiringducts?
nIsthepanelboxdeepenoughtoaccommodatetheXLE/XLT?
nIsthereadequateventilation?Istheambienttemperaturerangemaintained?Arecoolingorheatingdevices
required?
nArenoisesuppressiondevicesorisolationtransformersrequired?Isthereadequatedistancebetweenthe
baseoftheXLE/XLTandnoisydevicessuchasrelaysormotorstarters?Ensurethatpowerandsignalwires
arenotroutedinthesameconduit.
nArethereotherrequirementsthatimpacttheparticularsystem,whichneedtobeconsidered?
