3.3 Standard system components
3.3.1 Cable duct
Soft duct
The soft duct consists of flexible material that can be in-
stalled around the data and supply lines to be intro-
duced into the Micro Data Center. The cables to be in-
troduced must be distributed separately to the individual
positions. To ensure the guaranteed characteristics
against external danger potentials, no bundled cables
may be introduced into the Micro Data Center.
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:
– Steel tubes to max. 18 mm diameter
– 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 ca-
bles consists of a sheet steel enclosure lined on all sides
with alkaline-silicate blocks. In case of fire or tempera-
tures above 100 °C, this material swells and closes the
cable opening.
On the face side, the cable box is closed smoke-tight.
After the introduction of all cables and supply lines, the
cable entrance must be sprayed to become smoke
tight.
The cable box is divided into two areas:
– Dimension area 1: 26 x 214 mm
– Dimension area 2: 44 x 214 mm
To permit the passage of larger connector plugs, the
centre bar can be removed but must be replaced before
being sealed.
The cable box can be occupied 100%.
The cable box may be occupied with cables with maxi-
mum 15 mm diameter. The cable box may be occupied
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 cable
duct area, a hard duct can be deployed optionally. Each
cable is laid with a filler piece matched to the cable di-
ameter. An end seal ensures the pressing-in of the com-
plete 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:
– Cables to max. 15 mm diameter
3.4 Proper use, foreseeable misuse
The unit may be used only for the acceptance of IT com-
ponents while also providing protection against dan-
gers, such as fire, water or unauthorised access. Any
other use is not permitted.
The unit is state of the art and built according to recog-
nised 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 system and
other property.
Consequently, the unit must only be used properly and
in a technically sound condition! Any malfunctions which
impair safety should be rectified immediately! Observe
the operating instructions!
The intended use also includes the observance of the
provided documentation and fulfilling the inspection and
maintenance conditions.

Danger of collapse
The failure of the building structure can
cause severe injuries and death.
Prior to the assembly of the Micro Data
Center, check the requirements placed
on the building statics.
The Micro Data Center may be posi-
tioned only where the building structure
is dimensioned adequately.

6 Installation and commissioning Components of the Micro Data Center
Note:
The Micro Data Center may be installed and
commissioned only by trained specialists
certified by Rittal GmbH & Co. KG.
Note:
The installation and commissioning of the Mi-
cro Data Center is described in a separate in-
stallation 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 Center is designed only
for use with officially approved units.
The safety of the configuration must be
checked for the installation of units without
official approval. The installation of the units
must conform with the associated provisions
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 Center, you
should specify the placement of all compo-
nents.
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 or-
der and the location where you place compo-
nents in the rack.
Always place the heaviest components at the
bottom of the Micro Data Center. At least two
persons are required for the assembly and
disassembly of assemblies or components
that weigh more than 22.5 kg. A correct fas-
tening and the safe positioning of all compo-
nents and rack assemblies must always be
assured.

7.1 Handling the doors
Observe the following notes when you open and close
the doors of the Micro Data Center:
7.1.1 Mechanical key lock
Opening the Micro Data Center (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 counter-clockwise until the limit is
reached and open the Micro Data Center door.
Closing the Micro Data Center
Press slowly the Micro Data Center door at the side
opposite the hinges.
Turn the door handle clockwise until it is in the horizon-
tal position.
If the Micro Data Center door is closed too fast, this
produces an air buffer that prevents the Micro Data
Center door from closing.
Turn the inserted key counter-clockwise until the limit
is reached.
Remove the key.
Turn the lock cover downwards.
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 the doors. Maintain an adequate
safety clearance.
Confinement of persons
The confinement of persons in the not-
fully equipped Micro Data Center can
lead to injuries.
Before closing the not-fully equipped
Micro Data Center, 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 Center does
not tip. If necessary, secure it to a solid
surface.
Note:
The safety doors of the Micro Data Center
can be opened only to a limited extent. Do
not attempt to force the doors open further
because this would damage the Micro Data
Center.
Note:
Before you close the doors, the safety bolts
must be retracted.
Otherwise the Micro Data Center will be
damaged.
Note:
Before you lock the Micro Data Center, en-
sure that no key is still contained within it (not
even an emergency key)!
The interior of the Micro Data Center must
not be entered! The safety doors do not have
any panic unlocking on the inside.
Note:
Two keys are supplied as standard. All keys
must be retained at a safe place not accessi-
ble 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.
Note:
After the commissioning of the Micro Data
Center, do not have any keys duplicated by a
key service. If you require additional keys,
please contact the Rittal service department.
If keys get lost, the lock must be replaced
without delay.

Important safety instructions
Programming tasks should be performed only with
opened lock and opened safety doors!
Every correct key activation recognised by the lock is
confirmed with an acoustic signal. These confirmation
signals are not discussed in the following descriptions.
You have maximum 20 seconds for each individual key
input. If you do not operate any key within these 20 sec-
onds, the electronics switch off automatically. Any in-
complete operator actions must then be restarted.
Code inputs can be cancelled by pressing the Pkey.
The factory code setting for the lock is 123456. For safe-
ty reasons, change this factory code setting immediately
to your own personal code.
Do not use any personal or well-known number combi-
nations for your code.
If the battery is not accessible externally, the lock must
be opened using the inspection key for a discharged or
defective battery.
The inspection key must be kept in a safe place (but nev-
er inside the Micro Data Center).
The lock is designed for use in the temperature range
between +10 °C and +50 °C.
It must be cleaned only using a moist cloth (do not use
aggressive solvents).
The lock must not be greased.
Never open the lock housing. If the fittings need to be
dismantled, such work must conform to the specifica-
tions contained in these operating instructions. The non-
observance of these specifications can cause loss of
warranty claims.
If necessary, also refer to the operating instructions for
the Code-Combi B lock that accompany these operat-
ing instructions.

Operating modes
The lock can be opened with one code (primary code),
with two codes (primary or secondary code) or with a
dual code (primary and secondary subcode). Only the
holder of the higher-level primary code can release the
secondary and dual codes.
– Primary code: 6-digit secret number
– Secondary code: Additional 6-digit secret number for
other users
– Dual code: 12-digit secret number for two users of the
Micro Data Center formed from two 6-digit subcodes.
Both users must enter their 6-digit subcode to open
the lock (four-eyes principle).
For operating the lock, three operating modes are differ-
entiated. The opening authorisation of the different
modes is shown below. Parallel mode is the factory set-
ting.
The 1 2 3 4 5 6 factory code is programmed as primary
code.
