Rittal GmbH & Co. KG confirms the conformity of the
cooling unit with the European Union's Machinery Di-
rective 2006/42/EC and EMC Directive 2014/30/EC. A

sued. This can be found at the end of this document, or

2 Safety notes
Please observe the following general safety notes when
assembling and operating the unit:
– Assembly, installation and servicing may only be per-
formed by properly trained specialists.
– Screw the enclosure to the floor to prevent it from tip-
ping over when the cooling unit is installed.
– Do not obstruct the air inlet and air outlet of the cooling
unit inside and outside the enclosure (see sec-
tion4.2.2 "Layout of the electronic components in the
enclosure").
– To ensure problem-free opening and closing of the en-
closure door, use a ride-up door roller (refer to the ac-
cessories in the Rittal Catalogue). This raises the door
slightly and balances out the weight of the cooling unit,
to prevent buckling of the door and associated seal
problems.
– The heat loss of the components installed in the enclo-
sure must not exceed the useful cooling power of the
cooling unit.
– Cooling units with item numbers: 3303.xxx, 3361.xxx,
3304.xxx, 3305.xxx, 3328.xxx, 3329.xxx and
3332.xxx must be transported in an upright position
and protected from tipping over.
– Units with item numbers 3302.xxx and 3366.xxx must
be transported lying flat.
– Shipping braces must be used when transporting a
unit that has already been mounted (on the enclosure).
A wooden structure made from square timbers or
boards to support the cooling unit at the bottom (see
fig. 1) is suitable for this purpose. The pallet should be
big enough to prevent the enclosure and cooling unit
overturning. If the cooling unit is mounted on a door,
ensure the door is kept closed during transport.
– Use only original spare parts and accessories
– Do not make any changes to the cooling unit other
than those described in these instructions or associat-
ed instructions.
– Risk of burns! On cooling units with automatic con-
densate evaporation, the surface of the thermal ele-
ment will get very hot during operation, and will remain
so for some time afterwards.
– The mains connector of the cooling unit must only be
connected and disconnected with the system de-en-
ergised. Connect the protective device specified on
the rating plate.
Danger!

comply with the instructions will result in
death or severe injury.
Warning!
A dangerous situation which may cause
death or serious injury if the instructions
are not followed.
Caution!
