The Rittal Micro Data Centre Level E consists of indi-
vidual elements that are combined with a positive-
engagement connection system. The special connec-
tion system permits a subsequent dismantling and so
also an expansion of the system or its installation at a
different location.
High-temperature, expansion and water-resistant
seals are provided between the joints of the cell ele-
ments.
The cell elements themselves consist of a heat-insu-
lating special insulation with steam diffusion barriers
mounted in sheet steel modules.
In its standard variant, the modular safety cell consists
of a top and a floor element, two side elements, oper-
ator and service door as well as two mounting frames.
As standard, different locks are installed in both
doors. The two side elements are equipped with a ca-
ble duct.
The Micro Data Centre is equipped with a potential
equalisation rail that the customer must earth toa cen-
tral earthing point.
The customer must connect the frame correctly with
the potential equalisation rail. If a Rittal ITframe is

used, the scope of supply includes a central earthing
point that should be used for this purpose.
The split unit used for the cooling prevents dust and
corrosive combustion gases from entering the Micro
Data Centre. Several variants and power ranges
adapted to the heat loss and the customer conditions
can be chosen.
The CMC can optionally be used as network-compat-
ible monitoring system for monitoring the interior.
An early fire detection as well as fire alarm and extin-
guishing system can also be integrated as 482.6 mm
(19") components and offer a high degree of safety.
Various busbars adapted to the power distribution re-
quirements are available.
3.3 Standard system components
3.3.1 Cable duct
Note:
The connection of the cable ducts and also
expansions in a previously closed cable
duct may only be performed by authorised
service personnel otherwise the warranty
will be voided! If further lines or cables
should be inserted in a cable duct, the
manufacturer must be informed.
Soft duct
The soft duct consists of flexible material that can be
installed around the data and supply lines to be intro-
duced into the Micro Data Centre. The cables to be in-
troduced must be distributed separately to the individ-
ual positions. To ensure the guaranteed characteris-
tics against external danger potentials, no bundled
cables may be introduced into the Micro Data Centre.
After introduction of all cables, the complete area of
the cable duct is sealed externally and internally.
The soft duct has the dimension W x H 165 x 267 mm
and may be occupied with cables to the maximum
level of 60%.
The following cables and supply lines may be inserted
through the duct:
– Copper / steel tubes to max. 18 mm diameter
(min. 1 mm wall thickness)
– Cables to max. 15 mm diameter
When steel tubes are inserted, an additional cable
duct protection box must be placed in front of the soft
duct.
Cable box
The cable box for the introduction of data and supply
cables consists of a sheet steel enclosure lined on all
sides with alkaline-silicate blocks. In case of fire or
temperatures above 100°C, this material swells and
closes the cable opening. EN
On the face side, the cable box is closed smoke-tight
with plastic end caps. After the introduction of all ca-
bles and supply lines, the cable entrance must be
sprayed to become smoke tight.
The cable box is divided into two areas:
The dimension of each area is W x H: 214 x 33 mm
To permit the passage of larger connector plugs, the
centre bar can be removed but must be replaced be-
fore being sealed.
The cable box can beoccupied 100%.
The cable box may be occupied with cables with max-
imum 15 mm diameter. The cable box may be occu-
pied with 3311.040 water supply and return hoses for
the LCP. No steel tubes may be fed through the cable
box.
Hard duct
To guarantee large manipulation assurance in the ca-
ble duct area, a hard duct can be deployed optionally.
Each cable is laid with a filler piece matched to the ca-
ble diameter. An end seal ensures the pressing-in of
the complete system.
For stabilisation, the duct system is inserted in a con-
struction frame that absorbs the pressure.
The following cables and supply lines may be inserted
through the duct:
– Copper / steel tubes to max. 18 mm diameter
(min. 1 mm wall thickness)
– Cables to max. 15 mm diameter
When copper or steel tubes are inserted, an
additional cable duct protection box must be placed in
front of the soft duct and the tubes have to be
insulated with ArmaFlex Protect outside of the Micro
Data Center.
3.4 Proper use, foreseeable misuse
The unit may be used only for the acceptance of IT
components while also providing protection against
dangers, such as fire, water or unauthorised access.
Any other use is not permitted.
The unit is state of the art and built according to rec-
ognised safety regulations. Nevertheless, improper
use can present a hazard to life and limb of the user
or third parties, or result in possible damage to the

Installation and commissioning Components of the Micro Data Centre
Note:
The Micro Data Centre may be installed
and commissioned only by trained special-
ists certified by Rittal GmbH & Co. KG.
Note:
The installation and commissioning of the
Micro Data Centre is described in a sepa-
rate installation user's guide.
Caution:
482.6 mm (19") adjustment
There is danger caused by falling devices.
No devices may be installed on the internal
mounting rails when they are adjusted. The
failure to adhere to this rule can lead to se-
vere injuries and/or damage to devices.
Note:
The Rittal Micro Data Centre is designed
only for use with officially approved units.
The safety of the configuration must be
checked for the installation of units without
officialapproval.Theinstallation oftheunits
must conform with the associated provi-
sions for the installation of electrical units
and data-processing units.
The installation may be performed only by
trained specialists with the appropriate ap-
proval.
Prior to equipping the Micro Data Centre,
you should specify the placement of all
components.
The factors of the associated components,
such as weight, accessibility as well as the
requirements placed on the power supply,
temperature and air circulation, affect the
order and the location where you place
components in the rack.
Always place the heaviest components at
the bottom of the Micro Data Centre. At
least two persons are required for the as-
sembly and disassembly of assemblies or
components that weigh more than 22.5 kg.
A correct fastening and the safe positioning
of all components and rack assemblies
must always be assured.

7 Operation
7.1 Handling the doors
Observe the following notes when you open and close
the doors of the Micro Data Centre:
Danger of becoming trapped
Injuries can occur when the safety doors
are opened or closed.
Ensure that you do not reach between
the door and frame while opening and
closing thedoors. Maintain an adequate
safety clearance.
Confinement of persons
The confinement of persons in the not-
fully equipped Micro Data Centre can
lead to injuries.
Before closing the not-fully equipped
Micro Data Centre, ensure that no per-
sons are still present inside it.
Caution!
There is the danger of tipping when the
doors are opened 180° and the housing
is empty!
Ensure that the Micro Data Centre does
not tip. If necessary, secure it to a solid
surface.
Note:
The safety doors of the Micro Data Centre
can be opened only to a limited extent. Do
not attempt to force the doors open further
because this would damage the Micro Data
Centre.
Note:
Before you close the doors, thesafety bolts
must be retracted.
Otherwise the Micro Data Centre will be
damaged.
Note:
Before you lock the Micro Data Centre, en-
sure that no key is still contained within it
(not even an emergency key)!
The interior of the Micro Data Centre must
not be entered! The safety doors do not
have any panic unlocking on the inside.
7.1.1 Mechanical key lock EN
Note:
Two keys are supplied as standard. All
keys must be retained at a safe place not
accessible to unauthorised persons. If a
key is lost, the lock must be replaced!
Protect the key from dirt accumulation. The
lock must not be oiled or greased.
Opening the Micro Data Centre (DIN right-hand side)
Fig. 2: Door lock
◼Turn the lock cover upwards.
◼Insert the key in the key guide and turn it clockwise.
◼Turn the handle down until the limit is reached
and open the Micro Data Centre door.
Closing the Micro Data Centre
◼Slowly close the Micro Data Centre door by pressing
at the side opposite of the hinges.
◼Turn the door handle until it is in the hori- zontal
position.
If the Micro Data Centre door is closed too fast, this
produces an air buffer that prevents the Micro Data
Centre door from closing.
◼Turn the inserted key counter-clockwise until the lim-
it is reached.
◼Remove the key.
◼Close the lock cover downwards.
Note:
After the commissioning of the Micro Data
Centre, donot have any keys duplicated by
akeyservice.Ifyourequire additionalkeys,
please contact the Rittal service depart-
ment.
If keys get lost, the lock must be replaced
without delay.

7.1.2 Electronic combination lock Combi B 90
The Combi B 90 electronic combination lock is
equipped with a inspection key (for opening in an
emergency).
Read the operating instructions carefully before you
commission the lock and observe the safety in-
structions.
Fig. 3: Operator unit with key lock (optional)
Key lock (option)
Scope of supply / properties:
– Electronic lock
– Max. 90 six-digit codes can be programmed
– Battery operation with 2x AAA / LR03 1.5 V
batteries (batteries not included in the scope
of supply)
– Lock with integral battery compartment
– Acoustic and optical operator support
– Input unit: Die cast chrome plated
– Only for RC 2
The following information is taken from the operating
instructions of the Combi B lock. We reserve the right
to make technical and functional changes.
In case of doubt, the operating instructions of the
Combi B lock is valid.
Notes
After closing the lock by turning the actuation knob
counter clockwise, it has to be checked by turning the
knob clockwise to the stop, that the lock is correct
locked. The knob has to turn maximally 45°!
The enclosed inspection key allows full access to the
lock and its configurations even in case of code loss.
Thus, it is at the highest hierarchy level of the lock.
Therefore, it must be stored in a safe place, but not in
the secure storage unit.
For security reasons programming and battery
replacement should always be performed and then
tested with the secure storage unit open.
Every correct key stroke recognized by the lock is
confirmed by an acoustic signal.
You have max. 10 sec. for each individual key stroke.
If no key is pressed during these 10 seconds, the
electronics shuts down automatically. Uncompleted
operations must be restarted after that. The only
exceptions to this are the code status query and the
programming mode with 30 seconds response time
until automatic shutdown.
Code inputs resp. all further functions (e.g.
programming operations) can be cancelled until the
last key stroke by pressing the “P” key twice.
Do not use for your code personal or similar known
data which are easy to find out.
If the set code(s) is(are) not available, the lock can be
opened or reset using the enclosed inspection key.
The lock is designed for use in the temperature range
from +10° C to +50° C and with humidity of 30% to
80% (non-condensing).
The lock must never be greased with or contact other
lubricants or aggressive liquids, it must be cleaned
only with a moist cloth only (no aggressive cleaning
agents).
