Installation site requirements
Customer requirements:
The items listed below are the standard requirements
placed on the siting of the Micro Data Center Level E and
must be satisfied by the customer.
1. Transport path
An adequately dimensioned transport path for com-
ponents as large as 1300 x 2400 mm as well as ad-
equate storage and mounting area in the immediate
vicinity of the installation site area.
2. Fire-resistance class of the installation site surface
Fire-resistance class of the floor F 90 in accordance
with DIN 4102 for carrying or solid components.
3. Floor flatness
The installation site of the safety safe must be con-
structed level in accordance with DIN 18203
(smooth surface).
4. Room height
The clear height at the installation site of the Micro
Data Center must be at least 15 cm higher than the
height of the Micro Data Center. If the Micro Data
Center is equipped with cable entry in the top ele-
ment, appropriate additional space must be provid-
ed for the bending radiuses of the cables to be intro-
duced.
5. Traffic area / escape and rescue routes
The traffic area at the installation site of the Micro
Data Center must be adequately dimensioned not
only for the service and maintenance work and for
connecting the required cables. Accessibility from all
sides must be ensured. The escape and rescue
routes must remain free.
6. Room ventilation / climate control of the installation
site
The temperature at the installation site of the Micro
Data Center must lie in the range +10 °C to +35 °C.
If the external unit of the air-conditioner is mounted
directly on the Micro Data Center, the installation site
must be ventilated or air-conditioned appropriately.
7. Power supply / guaranteed climate control
– 3311.490 Liquid Cooling Unit LCU DX 3 kW:
operational voltage 230 V, 1 Ph/50 Hz/N/PE; line-
side time delay fuse 16 A
– 3311.491 Liquid Cooling Unit LCU DX 3 kW redun-
dant:
operational voltage 2 x 230 V, 1 Ph/50 Hz/N/PE;
line-side time delay fuse 16 A 2 x
– 3311.492 Liquid Cooling Unit LCU DX 6,5 kW:
operational voltage 230 V, 1 Ph/50 Hz/N/PE; line-
side time delay fuse 20 A
– 3311.493 Liquid Cooling Unit LCU DX 6,5 kW re-
dundant:
operational voltage 2 x 230 V, 1 Ph/50 Hz/N/PE;
line-side time delay fuse 20 A 2 x
– Power for the LCU DX must be supplied at the ex-
ternal unit.
8. Cut-outs
The customer is responsible for creating and closing
of the drilled tapped holes and cut-outs as well as
the opening and closing of the existing intermediate
floors and floors.
9. The customer must ensure that the protective con-
ductor is fed from outside and connected correctly
with the potential equalisation rail in the Micro Data
Center. This connection must be labelled (symbol
60417-ICE-5019). Always ensure that the protective
conductor has an adequate current-carrying capac-
ity.
10. Built-in components
Note that the selected built-in components (e.g.
CMC III monitoring system, DET-AC III fire alarm and
extinguishing system, etc.) require height units in the
482.6 mm (19") level.
The fire alarm and extinguishing system must be in-
stalled at the top in the 482.6 mm (19") level.
11. Requirements placed on the customer building
weight loadings
The floor at the installation site of the Micro Data
Center must be adequately dimensioned to accept
the static load of the Micro Data Center, including all
components.
The Micro Data Center must be installed on a level and
load-bearing bare reinforced-concrete floor in accord-
ance with Eurocode 2
[1]
as well as the associated Ger-
man national Appendix
[2]
for Eurocode 2. The floor
must be able to carry the uniformly distributed charac-
teristic live load of q
k
5.0 kN/m² (corresponds to
500 kg/m²) in the area of the Micro Data Center instal-
lation area at least with a two-axis construction.
If the floor construction does not conform to the speci-
fied European regulations or the Micro Data Center is in-
itially positioned on a floor covering or a floating floor, a
static calculation must be made prior to installation of
the Micro Data Center to check whether the floor-cover-
ing construction can handle the special loading for the
overall Micro Data Center load, also when it is fully
equipped.
If the floor construction conforms to the specified Euro-
pean regulations for a bare reinforced-concrete floor and
a uniformly distributed live load of
q
k
5.0 kN/m² is involved, the Micro Data Center may
also be installed without static calculation in the following
rooms in accordance with Eurocode 1
[3]
.
The bare floor loadings of q
k
5.0 kN/m² in accordance
with
[3]
