4 Installing the C-Hub
4.1 Requirements and General Installation Instruction
Warning
Risk of electric shock.
► Do not connect the unit to the power supply during installation.
Connection to the power supply must be performed by a trained, quali ed and author-
ised specialist.
Warning
Crushing hazard. 19" racks can be very heavy.
► At least two persons are required to carry 19" racks to avoid injuries.
4.1.1 Requirements for the C-Hub
Kathrein offers racks with the necessary characteristics. If other racks are used, these
must also satisfy the following required characteristics.
● The K-BOW system rack must be installed upright. This can be done by adjusting the
height-adjustable rack feet, using a spirit level.
● A 5-pin CEE socket and distributor according to DIN 60309 is required for the power
supply of each circuit in the power distribution bars. Two sockets are required for each
42-HU rack. One socket is required for the 24-HU rack. Each 5-pin CEE socket must
be protected by a D curve miniature circuit breaker (Europe) with 3 × 10 A (delay fuse).
● For the installation of the components, the rack must be accessible from at least one
side. To make installation of the components in the rack easier, we recommend that
the rack is accessible from two sides.
● The rear panel and side panels must contain lockable access doors. The doors must
extend over the entire rear and side panels.
● If you use racks which are not recommended by Kathrein, these racks must comply
with the following specications:
– 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.
