Starting Up
The NWA-6500 Series must be only operated with the nominal voltage of 12V ~ 19V DC
or 19V ~ 36V of type SELV. For details refer to the chapter 10/ “Technical
Specifications”.
8.1.
Connecting to DC Power Supply
The DC power input jack (Figure 2, pos. 1) or Phoenix connector (Figure 2, pos. 2) is located on the rear side of the
NWA-6500 Series. The NWA-6500 Series will be connected to a AC-to-DC power adapter via the supplied male DC
power plug and corresponding power cable attached to the adapter, or be connected to a DC main power supply via
the supplied Phoenix power plug terminal (see Figure 11) and corresponding power wires (prepared as described in
the subsection 7.1.1 "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 NWA-6500 Series 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
NWA-6500 Series.
The disconnecting device (fuse/circuit backer) rating must be in accordance with the
wire cross-section and the rated current of the NWA-6500 Series.
The cables must have some form of support so as to minimize the strain on the unit’s
connectors.
To connect the NWA-6500 Series to a corresponding DC power supply, please perform the following steps:
For model with DC jack:
1.
Connect the power adapter cable to the DC jack (DC IN, Figure 2, pos. 1) of the NWA-6500 Series.
2.
Connect the power cable to the power adapter.
3.
Connect the power cable to a power outlet.
For model with Phoenix connector:
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 plug terminal prepared as described in the subsection 7.1.1 "Cabling" to the DC input
Phoenix connector (Figure 2, pos. 2) of the NWA-6500 Series. The DC input connector is located on the rear side.
