7.2. DC Power Connection

Depending on the ordered configuration, the KBox F-420-WLU is connected by a 2-pin Phoenix connector (Figure 2,

pos. 1) via a DC power supply wiring or a DC power input jack (Figure 3, pos. 1) to a DC power source.

For the model with DC jack, the KBox F-420-WLU is delivered with a power adapter to convert AC voltage into DC 12 V

and a power cord to carry AC power to the power adapter.

For the model with 2-pin Phoenix connector, the KBox F-420-WLU is delivered with a 2-pin Phoenix power plug

terminal (Figure 21) attached on the system or a power adapter with a 2-pin Phoenix power plug terminal attached to

the adapter as well as a power cord depending on the ordered configuration.

In case of not ordering a power adapter from Kontron, prepare the connecting wires using the supplied Phoenix

power plug terminal for DC power connection. DC power voltage should be 19 V ~ 24 V.

In case of ordering a power adapter from Kontron, use the power cord and power adapter to carry AC power from AC

power source and then convert it into DC 12 V.

In case the supplied power adapter and Phoenix plug terminal are separated from each

other per your ordered configuration, the white wire of the adapter carries the positive

(+) end while the black one carries the negative (-) end.

1 Slotted pan head screw for securing the wire

2 Location for inserting the positive (+) input wire
