CAUTION:
If there is excessive condensate during normal operation
check the sealings of the switch cabinet.
We recommend that you install a door contact switch to
switch off the cooling unit, when the door of the switch ca-
binet is opened, in order to prevent excessive condensate.
8 Installation
8.1 General
• Theinstallationplacefortheswitchcabinetmustbeselected
such that proper ventilation of the cooling unit is ensured.
• Thesingleunitsortheunitsandthewallmustbeatadistance
of 200 mm at least.
• Aircirculationintheswitchcabinetmustnotbeimpededby
built-in parts.
• Theassemblyofthecoolingunitcanbecarriedoutwithand
withoutacover(external).(Theunitmustbedisconnected
fromthepowersupply!)
• Thesiteofinstallationmustbeprotectedagainstcontamination.
CAUTION
If the cooling unit is mounted on an switch cabinet door, it
mustbeconrmedthatthehingescansupporttheadditional
weight or that the switch cabinet will not topple over when
the door is opened
CAUTION: Chips may damage the switch cabinet.
If the required cutouts are only made in the switch cabinet
just before mounting of the cooling unit, make sure that swarf
is not allowed to enter the device hood by using a cover
sheet, for example.
Hint
To facilitate installation with heavy units, M8 lifting eyes can be
screwedintotheupperxingontheequipmenthousing.Simple
„onemaninstallation“istherebypossible.
8.2 Installation of side-mounted, bolt-on cooling unit
DTS
The mounting surface of the switch cabinet is to be provided with
cutout(s)andholesforairventilationopeningsandforsecuringthe
unit according to the accompanying sheet.
The drawing on the accompanying sheet also shows the location of
the electrical connections and ventilation openings.
1) Makecutout(s)anddrillingsforthecoolingunit,ifnotalready
providedintheswitchcabinet(seedrawingonaccompanying
sheet).
Remove burrs from the cut edges
2) Positiontheprolesealaroundtherimofthecutou(s)t.Position
the seal so that the impact ends are facing downwards.
3) Screwthetwothreadedstudsincludedinthecomponentpack
intotheupperxingpointofthecoolingunit.Suspendtheunit
from outside onto the switch cabinet using the threaded studs.
4) Usethescrews,nutsandwashersincludedinthecomponent
pack to secure the cooling unit on the inner side of the switch
cabinet.Tightenupxingssothatthesealiscompressedtoa
thickness of 2 mm.
5) Feedthecondensaterun-offtubethroughtheopeninginthe
base of the unit. Lay the tube with a downward fall. Shorten as
required.
6) Ifthecoolingunitismountedwithoutthedevicehood,plugthe
earth cable and the connecting cable to the display unit on the
hood and mount this on the cooling unit.
7) Clampthecableasshownintheconnectiondiagram(seeback
ofunit)totheplug(componentpack)andconnecttotheunit.
 -conductersize:0,5–2,5mm²orAWG20-AWG14(Intheselec-
tionofcablesize,therelevantregulationsmustbeobserved!)
8) Connecttheunittotheelectricalsupply(seeSection8.4).
8.3 Installation of built-in cooling unit DTI
The mounting surface of the switch cabinet is to be provided with a
rectangular cutout as shown on the accompanying sheet.
The drawing on the accompanying sheet shows the location of the
ventilation openings after mounting the unit as seen from the inside
of the switch cabinet.
1) Makecutoutforthecoolingunit,ifnotalreadyprovidedinthe
switchcabinet(seedrawingonaccompanyingsheet).
Remove burrs from the cut edges
2) Fromtheoutside,insertthecoolingunit(Pos.1)intothecutout
and push through until the unit seal engages with the switch
cabinet (Pos. 2). Close the snap-fasteners (Pos.4) with an
audible click from the unit or upper side and secure the unit
against falling out.

3) Ontheinsideoftheswitchcabinet,makesurethatthesecuring
springs(Pos.3)suppliedinthecomponentpackrestintheir
locations. To do this, compress the springs by hand so that the
securing bracket can be secured in the housing cutout.
In switch cabinets with reinforcing frames, insert the securing
springs in the rear of the housing cutouts.
4) Feedthecondensaterun-offtubethroughtheopeninginthe
base of the unit. Lay the tube with a downward fall. Shorten as
required.
5) Ifthecoolingunitismountedwithoutthedevicehood,plugthe
earth cable and the connecting cable to the display unit on the
hood and mount this on the cooling unit.
6) Clampcablesinaccordancewiththeconnectiondiagram(see
rearofunit)totheplug-inconnectors(enclosedpackage)and
connect to the unit.
