Assembly Instructions Manual
ACHTUNG!
Montage von
Schaltschrank-Kühlgeräten
Bei der Montage ist zu beachten, daß
Warmluftein- und Kaltluftaustritt nicht zu
verbauen sind. Eine ungehinderte Luft-
zirkulation im Innenkreislauf ist zu ge-
währleisten. Ein Abstand zu den Luft-
aus- und -eintrittsöffnungen von 200 mm
bis zur Installation ist einzuhalten. Wird
das Gerät vom Netz getrennt, darf ein
erneutes Einschalten erst nach einer
Wartezeit von > 5 min. erfolgen.
Einsatz von Türpositionsschaltern
bei Kühlgeräten
Serie .100 / .140: Die o.g. Wartezeit muß
z.B. durch die Verwendung eines
Zeitrelais sichergestellt werden.
Serie .500 / .540: Die o.g. Wartezeit wird
durch den integrierten Microcontroller
sichergestellt. Pro Gerät ist ein
potentialfreier Türpositionskontakt zu
verwenden; es dürfen auf keinen Fall
mehrere Geräte über einen Türend-
schalter betrieben werden.
In Umgebungen mit erhöhter elektro-
magnetischer Störung muß eine
geschirmte Leitung verwendet werden.
Der Türkontakt ist über zusätzliches
Relais, das in der Nähe des Gerätes pla-
ziert ist, zu schalten. Die Leitungen sind
getrennt von den Netzleitungen zu ver-
legen. Auf kurze Leitungswege achten!
Einsatz von Motor- bzw.
Trafoschutzschaltern bei Kühlgeräten
Drehstromgeräte sind über einen
Motorschutzschalter an ein TN-Netz mit
geerdetem Sternpunkt anzuschließen.
Beim Einsatz von Schaltschrank-Kühl-
geräten der Serie .140 / .540 mit
Transformatoren und Geräten in Sonder-
spannung, die ebenfalls mit Trafo
ausgerüstet sind, sind normale Motor-
schutzschalter von ihrer Einschalt-
charakteristik nicht mehr ausreichend.
Deshalb müssen kundenseitig Trafo-
schutzschalter installiert werden. Diese
sind auf den auf dem Typenschild
angegebenen Nennstrom einzustellen.
ATTENTION!
Installation of cooling units
Please make sure during installation that
warm air inlet and cold air outlet are not
obstructed. An unobstructed air circu-
lation in the inside circuit has to be
ensured. A distance of 200 mm from air
inlet and air outlet openings to the
installed equipment should be
respected. After disconnection of the
cooling unit, waiting period of > 5 min.
before reactivation.
Use of door operated switch with
cooling units
Series .100 / .140: The mentioned above
waiting period has to be ensured by
using a time relay.
Series .500 / .540: One potential-free
door operated contact has to be used
per unit, never operate more than one
unit via one door operated switch. In
environments with high electromagnetic
interference a shielded cable has to
be used. The door contact is to be
connected via an additional relay, which
is placed near the unit. The cables and
the supply line are to be laid separately.
Please ensure that the cables are as
short as possible.
Use of motor or transformer
protection switch with cooling units
Three-phase devices are to be
connected via a motor protection switch
to a TN network with earthed neutral. If
units of series .140 / .540 are used with
transformers and units with special
voltage, also equipped with transformer,
standard motor protection switches are
not sufficient due to their closed cricuit
condition. That is why transformer
protection switches have to be installed
by the customer, and have to be
adjusted to the rated current on the type
plate.
ATTENTION!
Montage des climatiseurs
d’armoires électriques
Veiller lors du montage à n’obstruer ou
gêner ni l’entrée de l’air chaud ni la
sortie de l’air froid. L’air doit pouvoir
circuler librement dans le circuit
intérieur. Respecter un écartement de
200 mm entre l’appareil installé et les
ouvertures d’entrée et de sortie d’air.
Lorsque l’appareil a été coupé du
secteur, attendre au moins 5 minutes
avant de le remettre en circuit.
Utilisation d’un interrupteur de porte
avec les climatiseur
Séries .100 / .140: La durée d’attente
mentionnée plus haut sera assurée en
installant un relais retardeur.
Séries .500 / .540: Utiliser un interrupteur
de porte sans potentiel pour chaque
appareil. Ne jamais faire fonctionner
plusieurs appareils avec un seul
interrupteur de porte.
Lorsque le milieu ambiant est soumis à
d’importantes interférences électro-
magnétiques, utiliser un câble avec
contacteur de protection. Monter le
contact de la porte avec un relais
supplémentaire placé à proximité de
l’appareil. Lors de la pose des conduc-
teurs, veiller à les séparer des lignes
d’alimentation et choisir la voie la plus
courte.
Utilisation d’un contacteur-disjoncteur
ou disjoncteur de protection pour
transformateur dans les climatiseurs
d’armoires électriques
Les appareils à courant triphasé doivent
être connectés par un contacteur-
disjoncteur au réseau TN avec neutre
mis à la terre. Dans le cas des climati-
seurs d’armoires électriques des séries
.140 / 540, équipés de transformateurs et
dans le cas des appareils avec tensions
spéciales également équipés de trans-
formateurs, les propriétés d’enclenche-
ment des disjoncteurs standard ne sont
pas suffisantes. Le client devra alors
prévoir des disjoncteurs de protection
pour transformateurs et les régler sur la
valeur du courant nominal indiquée sur
la plaque signalétique.
LET OP!
Montage van schakelkast-
koelaggregaten
Bij de montage dient erop te worden
gelet dat de aanzuigopeningen van de
warme lucht en de inblaasopeningen
van de koude lucht niet mogen worden
gemodificeerd. Anders kan geen
ongehinderde luchtcirculatie in het
binnencircuit worden gegarandeerd.
Tussen de luchtaanzuig-, luchtinblaas-
openingen en de installatie dient een
afstand van minimaal 200 mm te worden
aangehouden. Wordt het aggregaat van
het net gescheiden, dan mag het pas na
een wachttijd van tenminste 5 minuten
opnieuw worden ingeschakeld.
Toepassing van deurschakelaars bij
koelaggregaten
Serie .100 / .140: De hierboven genoem-
de wachttijd dient door toepassing van
bijv. een tijdrelais te worden zeker-
gesteld. Serie .500 / .540: Per aggregaat
dient één potentiaalvrij deurcontact te
worden toegepast; er mogen in geen
geval meerdere aggregaten op één
deurschakelaar worden aangesloten. In
omgevingen waar verhoogde elektro-
magnetische storingen voorkomen, dient
een afgeschermde kabel te worden
toegepast. Het deurcontact kan via een
extra relais, dat in de buurt van het
aggregaat is aangebracht, worden
geschakeld. De kabels diene geschei-
den van de netvoedingskabels te
worden gelegd. Let erop dat zo kort
mogelijke kabels worden gebruikt!
Inzet van motor respectievelijk
transformatorbeveiligingsschakelaar
bij koelaggregaten
Draaistroomaggregaten zijn via een
motorbeveiligingsschakelaar aan een
TN-stelsel met geaard sterpunt ann te
sluiten. Bij de toepassing van schakel-
kast-koelaggregaten van de serie .140 /
.540 met transformatoren en aggregaten
met afwijkende spanningen die ook
zijn voorzien van een transformator zijn
standaard motorbeveiligingsautoma-
ten niet voldoende als gevolg van hun
inschakelkarakteristiek. Daarom dienen
trafobeveiligingsschakelaars door de
klant zelf te worden geïnstalleerd en te
worden ingesteld volgens de op het type-
plaatje aangegeven nominale stroom.
VARNING!
Montering av
apparatskåpskylaggregat
Vid montering måste beaktas att
varmluftsintag och kalluftsutblås inte är
spärrade. En fri luftcirkulation inuti
skåpet måste garanteras. Utrymmet
mellan luftintag, utblåsöppningar och
installationerna måste vara 200 mm.
Efter att kylaggregatet stängts av kan
det startas först efter 5 minuter.
Användning av dörrkontakt med
kylaggregat
Vid serierna .100 / .140 måste den ovan
nämnda väntetiden åstadkommas
genom ett tidrelä.
Vid serierna .500 / .540 måste en
potentialfri dörrkontakt användas per
enhet, det får heller aldrig användas mer
än en enhet per dörrkontakt. I miljöer
med hög elektromagnetisk påverkan
måste en skärmad kabel användas.
Dörrkontakten ska kopplas via ytterligare
ett relö, vilket placeras nära enheten.
Kablage dras skiljt från nätledningen. Se
till att kablarna är så korta som möjligt!
Användning av motor- resp transfor-
matorskyddsbrytare med kylaggregat
Trefasaggregat ansluts via en
motorskyddsbrytare till ett TN-nät med
jordad nollpunkt. Om kylaggregat ur
serierna .140 / .540 används med
transformatorer och enheter med
specialspänning, även de utrustade
med transformatorer, räcker inte
standard motorskyddsbrytare beroende
på deras slutna kretsar. Därför måste
transformatorskyddsbrytare installeras,
Dessa ska ställas in på den på
typskylten angivna nätströmmen.
ATTENZIONE!
Installazione di condizionatori
Durante il montaggio accertarsi che
l’entrata aria calda e l’uscita aria fredda
non siano ostruite. Occorre assicurare la
libera circolazione dell’aria nel circuito
interno, nonchè rispettare una distanza
di 200 mm dalle aperture di entrata e
scarico aria al luogo di installazione.
Una volta disinserito l’apparecchio è
possibile riavviarlo soltanto dopo
> 5 min. di attesa.
Impiego di interruttori di posiziona-
mento porta nei condizionatori
Serie .100 / .140: il suddetto tempo di
attesa prima di riavviare l’apparecchio
deve essere rispettato utilizzando ad es.
un relais a tempo.
Serie .500 / .540: il tempo di attesa
sopra indicato viene assicurato dal
microcontroller integrato. Si deve
utilizzare un interruttore di posiziona-
mento porta per ogni apparecchio; non
è possibile in nessun caso azionare più
apparecchi con un interruttore.
In ambienti particolarmente soggetti ad
interferenze elettromagnetiche occorre
utilizzare un cavo schermato.
L’interruttore per la porta dovrà essere
collegato ad un ulteriore relais, situato
vicino all’apparecchio. I cavi e le linee
elettriche devono essere posati in sede
separata. Prevedere linee di connes-
sione con lunghezza limitata.
Impiego di interruttori di protezione
trasformatore nei condizionatori
I normalli interruttori di protezione dei
motori, per le loro caratteristiche, non
sono più sufficienti per essere impiegati
su condizionatori della serie .140 / .540
con trasformatori e apparecchiature a
tensione speciale, dotate anch’esse di
trasformatore: Il cliente dovrà quindi
installare interruttori di protezione del
trasformatore, da tarare in base al valore
della corrente nominale indicato sulla
targhetta.

1. Application
Enclosure cooling units are designed and built
to dissipate heat from enclosures, by cooling
the air inside the enclosure and protecting tem-
perature sensitive components. Enclosure cool-
ing units are particularly suitable for the
temperature range of + 40
°
C to + 55
°
C.
2.Technical Data
(see table 2.1)
3. Assembly
The cooling unit can be mounted either inter-
nally, partially internally or externally.
Make cutouts and drill holes at the mounting
position (see fig. 3.1). Cut the enclosed seal to
the required length and attach it to the unit (see
fig. 3.2). In the case of external mounting screw
set-screws M8 x 30 into the blind nuts at the
rear face of the unit and fix them by means of
washers A 8.4 and nuts M8. In the case of parti-
ally internal mounting the unit has to be divided
by removing the lamella grille and unscrewing
the nuts M8. For external, partially internal and
internal mounting see fig. 3.2.
Prior to mounting, ensure that:
v
the site for the enclosure, and hence the
arrangement of the cooling unit, is selected
so as to ensure good ventilation;
v
the location is free from excessive dirt and
moisture;
v
the round cut-out for air extraction is located
in the upper area of the enclosure;
v
the mains connection ratings, as stated on
the name plate, are available;
v
the ambient temperature is no higher than
+55
°
C;
v
the packaging shows no signs of damage;
v
the enclosure is sealed on all sides.
Condensation will occur if the enclosure is
leaky;
v
the separation of the units from one another
and from the wall should not be less than
200 mm;
v
air inlet and outlet are not obstructed on the
inside of the enclosure;
v
units are only fitted vertically in the specified
position. Max. deviation from true vertical: 2
°
;
v
condensate discharge must be made up by
means of the material provided in the dis-
patch bag. The discharge tube must be free
from kinks and must be arranged sloping
away from the unit;
v
electrical connection and repair are carried
out only by authorized specialist personnel.
Use only original replacement parts!
v
To avoid an increase in condensation, a door
operated switch (e.g. PS 4127.000) should
be used which will switch the cooling unit off
when the enclosure door is opened (see
5.2.3.3).
4.Electrical Connection
The connected voltage and frequency must corre-
spond to the values stated on the name plate. The
cooling unit must be connected to the mains via
an isolating device, which ensures at least 3 mm
contact opening when switched off. The unit must
not have any additional temperature control con-
nected before it. Line protection should be provid-
ed by means of the pre-fuse specified on the
name plate. Observe the relevant regulations
during installation!
Connect the mains connection to the plug-in ter-
minal strip X10, see page 35.
Version .....500 / .540
Door limit switch, see 5.2.3.3
v
Collective fault signal connection, see 5.2.3.1
v
Note the designations on the terminal strip (see
wiring diagram).
v
The unit must be disconnected prior to
checking the protective earth conductor, high
voltage and the insulation in the enclosure.
5. Commencing Operation
and Control Behaviour
Following the completion of mounting and a
waiting period of approximately 30 minutes (to
allow oil to collect in the compressor in order to
ensure lubrication and cooling) electrical connec-
tion can be made.
5.1 Control by Thermostat
Version .....100 / .140
The cooling unit operates automatically, i.e. follow-
ing the electrical connection, the evaporator fan
will run continuously to circulate the air inside the
enclosure. This provides a uniform temperature
distribution in the enclosure. The built-in tempera-
ture controller (setting the desired internal tempe-
rature) effects automatically controlled switch-off
of the cooling unit by the value of the fixed
switching difference setting of 5 K. This is set at
the factory to + 35
°
C.
5.1.1 Temperature Setting at the Controller

2. Remove locking plate.
3. Replace the setting knob and set the desired
temperature. Setting range + 20

5.2 Control by Microcontroller
Version .....500 / .540
Fig. 5.2
Microcontroller
After electrical connection the internal fan turns on
and circulates the enclosure air. This helps assure
even temperature distribution within the enclosure.
The condensor fan and compressor are controlled
by the microcontroller. The minimum run time is
90 seconds. The switching difference is 5 – 10 K
and is set at the factory. In order to maximize
energy efficiency the thermostat should be set to
the highest enclosure temperature as allowed by
the electronics.
5.2.1 Operation of the Microcontroller
The display terminal H1 consists of a 3 position
7-segment display which indicates the enclosure
internal temperature in
°
C or
°
F (changeable, see
section 5.2.2) as well as any fault codes. The
actual enclosure internal temperature is con-
stantly displayed. If a fault occurs then the fault
number is indicated in the left position. When pro-
gramming the microcontroller the program level
and parameter value is indicated on the display.
When the “TEST” button is pushed the compres-
sor and the fans will run for 5 minutes regardless
of the internal temperature or door limit switch.
This allows for a system test after an extended
shutdown period (e.g. after the winter).
5.2.2 Programming
(see diagram 5.1 page 39)
In the EEPROM of the microcontroller various
parameters are stored which can be changed
through using the “ENTER” and “ ” buttons,
9 different parameters are changeable as outlined
in table 5.1. To access the programming mode
push both the “ENTER” and “ ” buttons simulta-
neously for 10 seconds. The left digit will then
indicate the program level and the LED for the
“ENTER” and “ ” buttons will blink. By pushing
the “ ” button the program level can be advan-
ced to the next level. In order to access levels
5 through 9 a security code must be entered. If no
buttons are pushed for 60 seconds the display will
return to the standard mode which displays the
enclosure temperature. Programming of the para-
meters is made easy with diagram 5.1 on page
39. A description of the parameters to be pro-
grammed can be found in table 5.1. All parame-
ters are stored in the EEPROM and are retained
when power is shut off to the air conditioner.

5.2.3 Fault Signalling Facility
All faults on the cooling unit are registered and
indicated by H1 as a fault number. The display is
by means of the left-hand number. The display
cycles through all pending fault messages in a
2 second cycle, starting with the internal tempera-
ture of the enclosure.
H1 indicates the following faults as a fault number.
1 = Enclosure internal temperature too high
(5 K above setpoint value)
2 = Current monitor, condenser
3 = Evaporator (no collective fault indication).
4 = High-pressure monitor
5 = Current monitor, condenser fan
6 = Current monitor, evaporator fan
7 = Filter mat soiled
8 = Temperature sensor cable break/short-circuit
5.2.3.1 Fault Signal Contact
(K1, potential-free)
The fault signal relay is pulled in at normal condi-
tion. Any faults will cause the relay to drop out
(except low-pressure monitor, fault number 3).
Any failure of the control voltage will also lead to
drop-out of the relay and can thus be registered.
The connection is made on the terminal strip X10.
For contact data and assignment, see wiring dia-
gram.
5.2.3.2 Filter Mat Monitoring
The specified filter mat has large pores and filters
coarse dust and lint from the air. Oil condensate is
partially separated out. Fine dust is drawn through
the filter mat and the external circuit of the unit
due to the high suction power of the fan. It does
not have any damaging effect on the function of
the unit.
Fig. 5.3
Filter Mat Replacement
Function of the Filter Mat Monitor:
The filter mat is monitored for soiling by meas-
uring the temperature difference in the external
circulation of the cooling unit. In the event of any
filter mat soiling, the temperature difference will
increase. The setpoint value of the temperature
difference in the external circulation is adapted to
various air conditioner operating conditions. This
eliminates the need for subsequent adjustment of
the setpoint value for different operating points of
the unit. (For the setting of the filter mat replace-
ment see table 5.1 and fig. 5.1).
5.2.3.3 Door Limit Switch S 2
(supplied by costumer)
Where a door limit switch is used and the enclo-
sure door is open (contact is closed when door is
open), the cooling unit (fans and condenser) will
switch off after approx. 10 s, thereby avoiding an
increase in condensation while the door is open.
To avoid cyclic operation, switch-on of condenser
and external fan is delayed by about 3 minutes
after the door has been closed. The internal fan
will start up immediately on closure of the door.
Connection is made at the terminal strip X10, ter-
minals 1 and 2. The extra low voltage is supplied
by the internal power pack, current is approx.
30 mA DC (no extra low safety voltage). Connect
the door limit switch free from potential only, no
external voltage! The display will flash during the
door delay time. The system message “1010” is
transmitted via the PLC interface.
5.2.3.4 PLC Interface X2 (Option)
The interface is used for the transmission of the
actual internal temperature of the enclosure and
any system messages of the cooling unit to the
PLC. The transmitted information can be dis-
played by means of the output facilities (e.g.
plain text display) which are connected to the
PLC, or by means of the serial interface to a
higher order computer.
Construction of the PLC interface:
The construction is potential separated via opto-
coupler (wiring diagram fig. 5.4). Connection is
made by the customer to the 15-pin socket on the
control board (fig. 5.4) to the PLC input card.
Attention!
The electrical signals at the interface are of an
extra-low voltage (not extra-low safety voltages
according to EN 60335).
Fig. 5.4
PLC Interface
Max. loading of the outputs:
30 V/10 mA, direct current
Connection: screened 15-core control cable
The possibility exists to access this information
over the PLC interface (level 8, table 5.1 or
fig. 5.1).
a) Standard mode (Level 8 = “0”)
Communication of the enclosure internal tempera-
ture and of the fault messages is made succes-
sively in 2 s cycle. Since this is an 8-bit parallel
transmission, input signals should not be accept-
ed as valid in the PLC until they have been pres-
ent for 0.5 s. This ensures that no invalid input in-

System messages:
The system messages are transferred by means
of identification (4 bit) and a fault number
(1 digit BCD). The identification is structured as
follows:
In the event of a fault XXXX (BCD), the identifica-
tion is transmitted cyclically. This information
can be used to store the fault message in the
PLC.
This identification is transferred once, as soon
as the fault with the number XXXX/BCD has
been rectified. This information can be used to
delete the fault message in the PLC.
Evaluation of the interface signals in the PLC:
Messages:
If bit 1 and bit 3 of the input byte have a 1 signal,
the transmitted information is a system mes-
sage. In this case, the meaning of bit 0 is either
the information “store fault message” (bit 0 = 0)
or “cancel fault message” (bit 0 = 1).
Bit 4 to 7 represent the appropriate message
number (BCD).
Temperature:
If the AND operation of bit 1 and bit 3 is not fulfil-
led, the input information represents the actual
internal temperature of the enclosure. In this
case, both BCD digits have valid values (< = 9).
b) Parallel fault codes (Level 8 = “1”).
This can be accessed as follows:
Every one of the eight outputs stands for a cer-
tain system message (see below). It is not pos-
sible to display the internal temperature at the
same time as the system messages.

7.4 General
Storage temperature: The cooling units must not
be subjected to temperatures above + 70
°
C
during storage. Transport attitude: The cooling
units must always be transported upright. Waste
disposal: The closed cooling circuit contains cool-
ant and oil which must be correctly disposed of
for the protection of the environment. The disposal
can be carried out at Rittal-Werk.
Technical modifications reserved.
8. Maintenance
As a maintenance-free, hermetically sealed
system, the cooling circuit has been filled in the
factory with the required amount of coolant, and
tested for leaks and subjected to a function trial
run. The installed maintenance-free fans use bull
bearings, they are protected against moisture and
dust, and are fitted with a temperature monitor.
The life expectancy is at least 30,000 operating
hours. The cooling unit is thus largely mainte-
nance-free.
All that may be required from time is that the com-
ponents of the external air circuit are cleaned by
compressed air. The use of a filter mat is recom-
mended only if large particles of lint are present in
the air, so that blockage of the condenser is pre-
vented.
(Filter mat replacement, fig 5.3)
Caution: Prior to any maintenance work, the
power to the cooling unit must be disconnected.

6.BUS System
(Model No. SK 3124.000)
6.1 General
The BUS system allows a maximum of 7 cooling
units to be interconnected. As a result, the follow-
ing functions are available to the operator:
v
Parallel unit control
(the cooling units in the network can be
simultaneously switched on and off).
v
Parallel door status messages (“door open”).
v
Collective fault message.
The data exchange is carried out using cables
(shielded two-wire leads).
All units are assigned an address. This address
also includes the ID for “Master” or “Slave”.
The BUS system cannot be used to link the
cooling units to a PC.
The PLC interface is switched to parallel error
encoding.
NOTE
The following restrictions must be heeded:
only 6 outputs (0 to 5) are available;
outputs 5, 6 and 7 are routed in parallel to
output 5.
6.2 Notes Regarding Installation
ATTENTION!
The electrical signals at the interface are of an
extra-low voltage (not extra-low safety voltages
according to EN 60335).
Always heed the following notes!
v
De-energise the cooling units to be
connected.
v
Ensure proper electrical insulation.
v
Make sure the cables are not laid in parallel
to power lines.
v
Make sure that the lines are short.
6.3 Programming the Cooling Unit
See diagram 5.1 for details on programming.
IDs:
NOTE
Only one unit may be configured as master;
the address ID must match the number of slave
units.
The individual slave units must have different
addresses; the addresses must be in ascending
order (without gaps in between).
Example:
1 master cooling unit with 2 slave cooling units

7.Technical Information
The cooling unit (compression refrigeration unit)
consists of four main components: the coolant
compressor, evaporator, condenser, and the con-
trol or expansion valve, which are connected by
suitable pipework. This circuit is filled with a
readily boiling substance, the coolant. The
R134a (CH
2
FC
3
) coolant is free from chlorine. It
has an ozone destroying potential (ODP) of 0 and
is therefore environmentally friendly. A filter dryer
which is integrated in the hermetically sealed
cooling circuit, provides effective protection
against moisture, acid, dirt particles, and foreign
bodies within the cooling circuit.
7.1 Operation of the Cooling Unit
Fig. 7.1
Cooling Circuit
When a coolant compressor is put into operation,
the coolant vapour evaporates from the evapora-
tor. The heat required for the evaporation of the
coolant is drawn from the evaporator environment
(internal circuit of the enclosure), causing it to
cool down. The heat fed to the coolant in the
evaporator is its environment (assisted by fans),
making the coolant once more liquid due to the
condensation which takes place. In the thermo-
statically controlled expansion valve, the liquid
coolant is reduced to the particular evaporator
pressure required. The cooling which occurs due
to the reduction of pressure, releases the heat
from the liquid, which evaporates part of the cool-
ant flow. The mixture of cold liquid and throttle
vapour is returned to the evaporator. The cooling
cycle is thus completed, the aforementioned pro-
cess of the heat transfer starts afresh.
7.2 Safety Equipment
The cooling circuit of the cooling unit embodies
a component tested high-pressure monitor to
VBG 20.7.1 which is set to maximum operating
pressure and operates via an automatic reset
device at recurring pressure drop. Temperature
and low-pressure monitoring will prevent the eva-
porator from icing up. If there is a risk of icing up,
the condenser is switched off and automatically
switched on again at higher temperatures.
The coolant compressor and the fans are equip-
ped with thermal winding protection against
excess current and excess temperature.
7.3 Condensate Discharge
Condensate which may form on the evaporator
(under high air humidity, low enclosure tempera-
tures) is discharged through a hose at the eva-
porator partition, at the bottom of the unit. A
connection through the condensate support piece
is used to make this selection (see fig. 7.3, take off
the louvred grille if necessary). Blockage of con-
densate must be avoided.
