Starting Up
The QBOX-100P Series must be only operated with the nominal voltage of 12 V DC of
type SELV. For details refer to the chapter 10/ “Technical Specifications”.
8.1.
Connecting to DC Power Supply
The Phoenix connector (Figure 1, pos. 1) is located on the front side of the QBOX-100P Series. The QBOX-100P Series
will be connected to a AC-to-DC power adapter via the supplied Phoenix power plug terminal (see Figure 11) and
corresponding power cable attached to the adapter, or be connected to s DC main power supply via the supplied
Phoenix power plug terminal (see Figure 11) and corresponding power wires (prepared as described in the subsection
7.2.1 "Cabling").
Before using your system, become familiar with the system components and check that
everything is connected properly. 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 QBOX-100P Series must be connected DC main power supply complying with the
SELV (Safety Extra Low Voltage) requirements of EN 60950-1 standard. 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 QBOX-100P Series.
Even when the system is turned off via the power switch (Figure 1, pos. 2) 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 QBOX-100P Series.
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 QBOX-100P
Series and to the main power source, corresponding to signals marked; refer to Figure
11 and Table 5.
In addition, the cables must have some form of support so as to minimize the strain on
the unit’s connectors.
To connect the QBOX-100P Series to a corresponding DC main power supply, please perform the following steps:
For coonection to the supplied AC-to-DC power adapter:
1.
Connect the power adapter cable with Phoenix power plug terminal to the Phoenix connector (DC IN, Figure 1, pos.
1) of the QBOX-100P Series.
2.
Connect the power cable to the power adapter.
3.
Connect the power cable to a power outlet.
