2.2 Planning guide lines
2.2.1 Power supply principles
The FOX615 is designed for single or dual DC power supply. For the dual
power supply the DUPF1 dual power supply connection box (option) is
required. Both power feeding circuits are terminated in the DUPF1.
To cope with the high power capabilities of the FOX all power supply inter-
faces and the FOX power cabling use
• 2 conductors for the U
T
(-48/-60 V
DC
)
• 2 conductors for the 0 V and system ground
(subrack construction)
The cable tray can provide 1 or 2 connector blocks for external power supply
circuit(s) each able to connect 2 x 2 conductors for power feeding and power
return. The connector blocks can handle conductors with cross sections of
up to 4 mm
2
.
The paragraphs below describe recommended implementations of the power
supplies for the FOX.
2.2.2 Power supply circuits
The power supply circuits for the FOX615 power supply can be
• directly connected to the remote DC power distribution point:
Each remote power distribution point has its own circuit breaker to fuse
the supply circuit up to the FOX subrack. The circuit breaker is also used
as a disconnect device for the subrack.
This rack wiring diagram, without the remote DC power distribution point,
is shown on the left side of
Figure 1 .
• connected to a power connection block in the rack.
The power distribution points for all the equipment in the rack are imple-
mented in the rack. Each power distribution point has its own circuit
breaker “CB 1” to fuse the supply circuit up to the FOX615 subrack. The
circuit breaker is also used as a disconnect device for the subrack.
This rack wiring diagram is shown on the right side of
Figure 1 .
For single power supply of the FOX only the power supply circuit “PSC
1
” is
implemented. For dual power supply with the DUPF1 the power supply cir-
cuits “PSC
1
” and “PSC
2
” are implemented.
For details of the DUPF1 installation, refer to section Installing DUPF1
(option) (on page 51).
