Starting Up
The SmartClient-BSW must be only operated with the nominal voltage of 12 V DC of
type SELV. For details refer to the chapter 9/ “Technical Specifications”.
7.1.
Connecting to DC Power Supply
The DC power input connector (Figure 1, pos. 1) is located on the rear side of the SmartClient-BSW. The SmartClient-
BSW will be connected to a DC main power supply via the supplied Phoenix power plug terminal (see Figure 11) and
corresponding power wired (not included).
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 SmartClient-BSW must be connected DC 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
SmartClient-BSW.
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 SmartClient-BSW.
The cables must have some form of support so as to minimize the strain on the unit’s
connectors.
To connect the SmartClient-BSW to a corresponding DC power supply, please perform the following steps:
1.
Ensure that the DC power source is switched off via a disconnecting device (circuit breaker), in order to ensure
that no power is flowing from the external DC power source during the connection procedure.
2.
Connect the Phoenix power terminal prepared as described in the subsection 6.2.1 "Cabling" to the DC input
connector (Figure 1, pos. 1) of the SmartClient-BSW. The DC input connector is located on the rear side.
3.
Connect the other ends of the DC power wires to the connections of the DC main power supply. Pay attention to
the polarity of the connections.
4.
Switch on the disconnecting device (circuit breaker) in order to apply voltage to the terminals of the power wires.
5.
Press the power switch (Figure 1, pos. 2) on the rear panel to turn on the system.
