2. Safety instructions
2.1 Intended use
The VX IT is a high-quality enclosure for accommodating 482.6 mm (19˝)
hardware to industry standard EIA-310, which includes various types of
server, data storage devices, network and internet components as well
as emergency power supplies and the infrastructure components
needed to operate them. Please only use approved terminal equipment
with connectors and equipment intended for this type of installation
which is suitable for installation and operation by untrained staff .
The VX IT is only intended for stationary use. Castors included with the
supply or available as accessories are only suitable for moving empty or
pre-installed racks on fl at surfaces without any obstacles on site up to
the point of installation.
The VX IT is suitable for baying to other VX IT and TS IT racks with an
identical enclosure height and depth. To this end, further accessories are
required (see page 65).
Depending on the design, some VX IT enclosures are fi re-resistant and
resistant to splashed water and dust.
Please observe the information in the technical specifi cations, the RiCS
confi guration documents and the rating plate of the respective product.
Restrictions to admissible use:
◾ Not to be used as an enclosure which needs to off er signifi cant
protection against access to live parts and which serves as an earthed
enclosure for Class 1 devices.
Rittal accessories may be used to upgrade the VX IT to meet more
stringent requirements.
In this regard, the specifi cations for the accessories must be observed.
2.2 User groups to IEC 62 368
◾ Skilled persons as defi ned in IEC 62 368 (familiar with the specifi ca-
tions, technical limitations and safety instructions):
A skilled person is able to perform the following tasks (not an
exhaustive list): transportation, assembly/dismantling, installation,
retrofi tting, operation and servicing.
◾ Instructed persons as defi ned in IEC 62 368 (instructed by a skilled
person and/or with access to the assembly and operating instruc-
tions):
An individual who has been instructed by a skilled person or an
individual capable of applying information from the operating and
assembly instructions and who is equipped with the necessary tools
and protective clothing. An instructed person is limited to the following
tasks: Installation, retrofi tting, operation and servicing.
◾ Ordinary persons as defi ned in IEC 62 368 (able to identify warning
signs, without access to the installation and operating instructions,
use of the VX IT is not authorised):
Individuals working in the vicinity, including but not restricted to IT
personnel, cleaning staff , data centre staff , visitors, offi ce personnel.
2.3 Safety instructions
These installation and operating instructions contain important informa-
tion which must be followed when installing and modifying the enclo-
sure. In the following chapters, a warning symbol will alert you to relevant
safety instructions and other important information (explanation of safety
symbols, see page 30 – 37).
◾ In the basic confi guration, not all electrically conductive parts are
conductively connected to one another and no central earthing point
is fi tted.
◾ Preinstalled VX IT on castors may only be moved if the centre of
gravity of the installation is below the 13th height unit. The fi rst height
unit in the VX IT is at the bottom of the rack. This requirement should
be taken into account when populating the VX IT with installed
castors.

◾ Note: Where there is an asymmetrical distribution of weight, the
stability of the VX IT is at risk. Never simultaneously open the doors
and a hinged, divided side panel mounted on the same side as the
door hinge without fi rst securing the VX IT to the fl oor.
◾ Caution when using telescopic slides: The VX IT must be secured
to the fl oor or bayed to other VX IT or the stabiliser (5301.325) must be
used before extending devices on telescopic slides.
Only one device at a time may be in the set forward position.
If for some reason more than one device is extended at the same time,
the stability of the VX IT may be at risk.
◾ Caution: Never stand on the roof plate!
Failure to follow these instructions may lead to serious injury, damage to
property or, in a worst case scenario, even death.
