Starting Up
The KBox C-103-NGSF must be operated only with the nominal voltage of
24V DC of type SELV. For details refer to the chapter 11/ “Technical
Specifications”.
8.1.
Connecting to DC Main Power Supply
The DC input connector (Figure 9 and Figure 11 marked X101) is located on the front side
of the KBox C-103-NGSF. The
KBox C-103-NGSF will be connected to a DC main power supply via the supplied Phoenix
power plug terminal (see Figure 31) and corresponding power wires (prepared as described
in the subsection 7.3.1 “Cabling”).
Before using your system, become familiar with the system components
and check that everything is properly connected. Following a proper
cabling procedure will prevent a false power-on condition, which could
result in unit operational failure.
When you install/disconnect the unit, the functional earth connection
must always be made first and disconnected last.
Also, it is recommended that the last connections attached to the
system should be the power wires!
The KBox C-103-NGSF must be connected to a DC mains power supply
complying with the requirements of IEC 61010-1 and IEC 60950-1
standard or better. It must be observed that wiring and short-
circuit/overcurrent protection is performed according to the
applicable standards, regulations and respect to the electrical
specification of the KBox C-103-NGSF.
Even when the system is turned off via the power button (Figure 9 and
Figure 12, marked PWR) parts of the system are still energized.
The disconnecting device (fuse/circuit backer) rating must be in
accordance with the wire cross-section and the rated current of the
KBox C-103-NGSF.
The wires used for power connections must be clearly marked (+/-
/functional earth) to ensure that they will be proper connected to the
DC IN connector of the KBox C-103-NGSF and to the main power source,
corresponding to signals marked; refer to Figure 11 and Figure 31.
In addition, the cables must have some form of support so as to
minimize the strain on the unit’s connectors.
Only connect to an external power supply delivering the specified
input rating and compling with the requirements of Safety Extra Low
Voltage (SELV) and Limited Power Source (L.P.S.) of UL/IEC 60950-1 or
(PS2) of UL/IEC 62368-1.
To connect the KBox C-103-NGSF to a corresponding DC main power supply, please perform
the following steps:
