Start Up
The KBox E-420-R1K/V1K must be only operated with the nominal voltage of 12 V DC of
type SELV for models with DC jack or of 19 V ~ 36 V DC for models with Phoenix
connector. 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 3, pos. 1) is located on the rear side of the KBox
E-420-R1K/V1K. The KBox E-420-R1K/V1K will be connected to a AC-to-DC power adapter via the attached male DC
power plug or supplied Phoenix power plug terminal (Figure 18) as well as corresponding power cable to couple
together the adapter and the AC power outlet, or be connected to a DC main power supply via the supplied Phoenix
power plug terminal (Figure 18) 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 KBox E-420-R1K/V1K 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
KBox E-420-R1K/V1K.
Even when the system is turned off via the power button (Figure 1, pos. 1) 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 E-420-R1K/V1K.
The wires used for power connections must be clearly marked (+/-) to ensure that they
will be proper connected to the DC IN connector of the KBox E-420-R1K/V1K and to the
main power source, corresponding to signals marked; refer to Figure 18 and Subsection
11.1.
The cables must have some form of support so as to minimize the strain on the unit's
connectors.
To connect the KBox E-420-R1K/V1K to a corresponding power supply, please perform the following steps:
For connection to the supplied AC-to-DC power adapter (models with DC jack) or optional AC-to-DC power adapter
(models with Phoenix connector in case of ordering the power adapter from Kontron):
1.
Connect the power adapter cable with DC power plug or Phoenix power plug terminal to the DC jack (DC IN, Figure
2, pos. 1) or the Phoenix connector (DC IN, Figure 3, pos. 1) of the KBox E-420-R1K/V1K.
2.
Connect the power cable to the power adapter.
