Safety instructions
– Work on electrical systems or equipment may only be
carried out by an electrician or by trained personnel
under the guidance and supervision of an electrician.
All work must be carried out in accordance with elec-
trical engineering regulations.
– The cooling unit may only be connected after the
aforementioned personnel have read this information!
– Use only insulated tools.
– Follow the connection regulations of the appropriate
electrical supply company. Otherwise, there is risk of
injury from electric shock if the connection to the unit
is defective or connected incorrectly in any way.
– The cooling unit must be connected to the mains via
an all-pole disconnecting device to overvoltage cate-
gory III (IEC 61058).
– Do not strip too much insulation from the connection
cable, otherwise the admissible clearance/creepage
distances from the terminal point may not be met.
– Pin 4 on the signal connector should not be used. Oth-
erwise, the admissible clearance/creepage distance
between the alarm relay and door contact connec-
tions will not be met.
– The cooling unit is not de-energised until all of the volt-
age sources have been disconnected!
– Do not assemble and re-activate the device until it is
completely dry.
Please note the maximum weights that may be lifted
by individuals. It may be necessary to use lifting gear.
During assembly, the cooling unit is at risk of dropping
through the mounting cut-out.
Always wear the required personal safety equipment
when working on this device.
Please be sure to observe the applicable regulations
governing electrical installations of the country in
which the device is installed and operated as well as
national regulations for accident prevention. Please
also observe any internal company regulations, such
as work, operating and safety regulations.
The technical specifications and limit values stated
must not be exceeded under any circumstances. In
particular, this applies to the specified ambient tem-
perature range and IP protection category.

Siting location requirements
When choosing the installation site for the enclosure,
please observe the following:
– The site for the enclosure, and hence the positioning
of the cooling unit, must be carefully selected so as to
ensure good ventilation (distance between cooling
units at least 200 mm, distance from wall see distance
"y" in fig. 7 or tab. 2).
– The cooling unit must be installed and operated with a
maximum deviation of 2° from the vertical.
– The installation site must be free from excessive dirt,
aggressive ambient conditions and moisture.
– The ambient temperature must not exceed 60 °C.
– It must be possible to fit a condensate water discharge
(see section 5.3.6 "Connect the condensate water
discharge").
– The mains connection data as stated on the rating
plate of the cooling unit must be guaranteed.
Electromagnetic interference (EMI)
– Interfering electrical installations (high frequency) must
be avoided.
– Signal cables must be laid separately from live cables.

Assembly procedure
5.3.1
Assembly instructions
Before starting assembly, please ensure that the fol-
lowing tools are available:
– Allen key SW4
– Open-end spanner SW13
– Phillips-head screwdriver
Before assembling, please ensure that the enclosure
is sealed on all sides (IP 54). Increased condensation
will occur later during operation if the enclosure is not
airtight.
If applicable, additionally fit a door limit switch (such as
4127010) to the enclosure which switches off the
cooling unit when the enclosure door is opened to pre-
vent excessive condensation (see section 3.1.7 "Door
limit switch").
Please ensure that the electronic assemblies in the en-
closure allow the even circulation of air.
Measure the distance "x" (fig. 7) from electronic com-
ponents and other installed equipment inside the en-
closure so that the required air circulation is not
obstructed.
