
1. CarefullylocateanappropriateplacetomounttheEXL6/XL6PRIME.Besuretoleaveenoughroomatthe
topoftheunitforinsertionandremovalofthemicroSD™card.
2. Carefullycutthehostpanelperthediagram,creatinga131.9mmx175.0mm,witha+1mm/-0mmopening
intowhichtheEXL6/XL6PRIMEmaybeinstalled.Iftheopeningistoolarge,watermayleakintotheenclos-
ure,potentiallydamaging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EXL6/XL6PRIME.InserttheEXL6/XL6PRIMEthroughthe
panelcutout(fromthefront).ThegasketmustbebetweenthehostpanelandtheEXL6/XL6PRIME.
5. Installandtightenthefourmountingclips(providedinthebox)untilthegasketformsatightsealNOTE:Max
torqueis0.8to1.13Nm,or7to10in-lbs.
6. ReinstalltheEXL6/XL6PRIMEI/ORemovableTerminalBlocks.Connectcommunicationscablestothe
serialport,USBports,Ethernetport,andCANportasrequired.

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.)
2”(50.80mm)

Mechanical Installation
Grounding
Panel Box:Thepanelboxmustbeproperlyconnectedtoearthgroundtoprovideagoodcommongroundref-
erence.
Panel Door:Tiealowimpedancegroundstrapbetweenthepanelboxandthepaneldoortoensurethattheyhave
thesamegroundreference.

WARNING:Besuremeetthegroundrequirementsofthepanelmanufactuerandalsomeetapplicableelectrical
codesandstandards.


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OCSandnoisydevicessuchasrelays,motor
starters,etc.


Shock and Vibration
TheOCShasbeendesignedtooperateintypicalindustrialenvironmentsthatmayinflictsomeshockandvibration
ontheunit.Forapplicationsthatmayinflictexcessiveshockandvibrationpleaseuseproperdampeningtechniques
orrelocatetheOCS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controller?
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controller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?
