1 Notes on documentation
1.1 CE labelling
Rittal GmbH & Co. KG confirms the conformity of the
cooling unit with the European Union's Machinery Direc-
tive 2006/42/EC and EMC Directive 2014/30/EU. A sim-
plified declaration of conformity can be found in the as-
sembly and installation instructions enclosed with the
device (see also the Rittal website). These are the origi-
nal operating instructions.
1.2 Storing the documents
The assembly and operating instructions as well as all
other applicable documents are an integral part of the
product. They must be issued to everyone who works
with the unit and must always be available and on hand
for operating and maintenance personnel.
1.3 Symbols used in these operating in-
structions
The following symbols are used in this documentation:
This symbol indicates an "action point" and shows that
you should perform an operation or procedure.
1.4 Other applicable documents
Paper copies of the assembly and operating instructions
are available for the unit types described here and are
enclosed with the equipment.
We cannot accept any liability for damage associated
with failure to observe these instructions.
Please also observe the instructions for any accesso-
ries used.
Warning!
A dangerous situation which may cause
death or serious injury if the instructions
are not followed.

2 Safety instructions
2.1 General safety instructions
Please observe the following general safety instructions
for the installation and operation of the system:
– Always wear the required personal safety equipment
when working on this device.
– Before removing the hood, allow the unit to cool for at
least 10 minutes to eliminate the risk of burns from hot
surfaces.
– Please do not make any changes to the cooling unit
that are not described in these operating instructions
or other applicable assembly and operating instruc-
tions.
– The products should only be combined and operated
with the prescribed Rittal system accessories.
– Other than these general safety instructions, it is also
vital to observe the specific safety instructions when
carrying out the tasks described in the following chap-
ters.
2.2 Safety instructions for transportation
– Please observe the maximum permissible weight to be
lifted by one person. Use suitable lifting devices, if
needed.
– Cooling units must be transported in an upright posi-
tion and secured to prevent them from tipping over.
– Shipping braces (such as a structure made from
square timbers or boards) must be used when trans-
porting cooling units already mounted on the enclo-
sure. These braces support the cooling unit and pre-
vent it from slipping in case of impact.
– Use a sufficiently large pallet to prevent it tipping over.
– If the cooling unit has been mounted on a door, close
the door and keep it closed during transportation.
2.3 Safety instructions for assembly
– During assembly, the cooling unit is at risk of dropping
through the mounting cut-out.
– Do not assemble and re-activate the device until it is
completely dry.
2.4 Safety instructions for installation
– 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 connection regulations of the appropriate power
supply company are to be followed. Otherwise, there
is risk of injury from electric shock if the connection to
the unit is defective or connected incorrectly in any
way.
– Do not strip too much insulation from the connection
cable, otherwise the admissible clearance/creepage
distances from the terminal point may not be met.
– The cooling unit must be connected to the mains via
an all-pole disconnect to overvoltage category III (IEC
61058-1).
– 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.
2.5 Safety instructions for operation
– The operational safety of the cooling unit is only war-
ranted if used as intended. The technical specifica-
tions and limit values stated must not be exceeded un-
der any circumstances. In particular, this applies to the
specified ambient temperature range and IP protec-
tion category.
– Operating the cooling unit in direct contact with water,
aggressive materials or inflammable gases and va-
pours is prohibited.
2.6 Safety instructions for maintenance
– The device must only be cleaned by trained special-
ists. De-energise the device prior to cleaning.
– Never use flammable liquids for cleaning.
2.7 Operating and technical staff
– The assembly, installation, commissioning, mainte-
nance and repair of this cooling unit may only be per-
formed by qualified, trained personnel.
– Only properly instructed personnel may operate a
cooling unit with the system operational.
– Children and persons with limited cognitive/coordina-
tive abilities must not operate, maintain or clean the
unit or be allowed to use it as a toy.
2.8 Other dangers when using the cooling
unit
When installing the cooling unit (see section 5 "Installa-
tion"), there is a risk that the enclosure could become
unbalanced and tip over.
In such cases, the enclosure should be bolted to the
floor as a precaution.
If the air inlet or outlet of the cooling unit is obstructed,
there is a risk of air short-circuits, resulting in inadequate
climate control.
Please ensure that the electronic assemblies in the en-
closure are installed in accordance with section 5.3.1
"Assembly instructions".
Where applicable, use suitable components to divert
the air.
Please observe the prescribed minimum distances at
the installation site as outlined in section 5.3.1 "As-
sembly instructions".
2.9 IT safety instructions
To ensure the availability, confidentiality and integrity of
data, products, networks and systems must be protect-
ed against unauthorised access.
