2.2 Safety Requirements for the Installation Locations
2.2.1 General
● Install the K-BOW system indoors only and as a stationary system in weather-protected
and temperature-controlled locations.
● Comply with the permissible ambient conditions stated in the data sheets of the K-BOW
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 installation location of system racks must satisfy the following requirements:
● 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 –5 to +55°C (ambient air).
1)
● If required, install active cooling (air conditioning) to ensure the permissible ambient
temperature of the system is satis ed.
● 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
3
/h unimpeded air ow.
1)
The permissible ambient temperature range applies to the racks recommended by Kathrein.
These racks ensure optimum dissipation of heat.
