2.2 Safety Requirements for the Installation Locations
2.2.1 General
● Install the C-hub and the E-hub indoors only as a stationary system in weather-protected
and temperature-controlled locations. Sole exception are the HPRUs which are IPxx
protected.
● Comply with the permissible ambient conditions stated in the data sheets of the
K-BOWplatform2 components.
●
Ensure that only authorised personnel are allowed access to the installation location(s) of
the system rack (main rack and extension racks).
2.2.2 Installation Location of System Racks
● The static loading calculations must ensure that a rack up to 500kg in weight can be
erected and operated.
● The permissible ambient temperature range of the system is –10to +45°C(ambientair)
1)
,
the permissible maximum humidity is 85%. For more details, see the data sheets of the
individual devices.
● If required, install active cooling (air conditioning) to ensure the permissible ambient
temperature of the system is satis ed.
● For proper ventilation, the clearance above and below each C-hub or E-hub must be at
least 2HU.
● The installation location must be larger than 1000×800×2500mm.
● The safety clearance between rack and adjacent walls must be at least 200mm.
● The safety clearance between adjoining systems must be complied with. See the
speci cations of the companies operating the adjoining systems.
● If you use racks other than those recommended by Kathrein, make sure that the
following conditions are satis ed:
– All height units not used must be blanked off.
– The door must permit the passage of air over its entire surface, for instance by
perforation.
– The cooling air must ow through the rack from the front between the K-BOW
components, upwards and to the back where it is exhausted.
– The cooling air fans at the top of the rack must be capable of a throughput of
≥960m

The permissible ambient temperature range applies to the racks recommended by Kathrein.
These racks ensure optimum dissipation of heat.
