4.2 Power Distribution Bars
Notice
Risk of reduced operational reliability because of power failure. Make sure that the
230 VAC power supply to the K-BOW system rack satises the following conditions:
● 3 or 6 power distribution modules are used in order to ensure redundancy of the power
supply; see the planning document. Furthermore:
– For reasons of operational reliability (redundancy), each power distribution module
must be connected to a different phase.
– Each of the 3 PSUs of the PDU, BSR, FSR is connected to its own power distri-
bution module.
– A maximum of 4 PSUs may be connected to each power distribution module.
● The power available must correspond to the power consumption of the K-BOW
system. The required amount of power supplies is specied in the rack layout plan
depending on the system design.
● The electrical fuses and protective elements in the power supply must match the
power consumption of the K-BOW system and satisfy the national regulations.
● The grounding conductors (potential equalisation) and data conductors (incl. hybrid
cables) must at all points be at least 50 mm apart. Therefore, use separation strips
in cable ducts and on cable trays.
A. Install the power distribution modules to the power distribution bar on the left-hand side
of the rack (① in Fig. 6). In doing so, install the rst three modules with the red arrow ②
facing upwards, and the next three modules (if required) with the black arrow facing
upwards.
B. Plug in the power cable on the top of the power distribution bar:
– For the three modules in the red circuit (red arrow faces upwards), use the
connection on the left side (① in Fig. 7).
– For the tree modules in the black circuit, use the connection on the right side (②).
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.
