8.1. Connecting to DC Power Supply

The AC-in power socket (Figure 2, pos. 1) is located on the rear side of the RAK-120S. The RAK-120S is supplied with a
AC power cord.
Power cable and power connectors must always remain easily accessible.
The RAK-120S is only completely disconnected from the mains power supply when the
power cable is disconnected, either from the mains power socket, or the system's input
power socket (Figure 2, pos. 1).
If the end environment restrict access to power cable, disconnection must be
guaranteed using a separate cut-off fixture.
Ensure that the mains power supply socket (power outlet) is properly grounded and
the power cable is in perfect condition with no visible damage.
The rated mains voltage range must agree with the voltage specified on the type label.
Do not disconnect the power from the system while the system is powered up!
Performing a forced shut down can lead to loss of data or other undesirable effects!

supply socket using the electrical plug for the region.
2. Press the power switch (Figure 1, pos. 1).
