Requirements for connecting the supply voltage
The following requirements apply without restrictions:
All of the following requirements are complied with:
The supply voltage corresponds to the voltage specified on the type plate of the device.
The power supply conforms to overvoltage category I or II.
The power supply has an easily accessible disconnecting device (e.g., a switch or a plug).
This disconnecting device is clearly identified. So in the case of an emergency, it is clear
which disconnecting device belongs to which power supply cable.
The power supply cable is suitable for the voltage, the current and the physical load.
Hirschmann recommends a wire diameter of at least 0.75 mm² (AWG18).
The following requirements apply alternatively:
Alternative 1
The power supply complies with the requirements for a limited power source
(LPS) as per EN 60950-1.
Alternative 2
Relevant for North America:
The power supply complies with the requirements as per NEC Class 2
Alternative 3
All of the following requirements are complied with:
The power supply complies with the requirements for a safety extra-low
voltage (SELV) as per IEC/EN 60950-1.
A fuse is located in the plus conductor of the power supply.
The minus conductor is on ground potential. Otherwise, a fuse is also
located in the minus conductor.
Regarding the properties of this fuse:

Lightning protection
The installation of the device occurs in accordance with valid
standards (such as VDE 0185 and IEC 62305), and in accordance
with the lightening protection procedures recognized and proven for
the application and the environment.
Refer to the information in the "WLAN Outdoor Guide" on "lightening
and overvoltage protector".
Protect antennas installed outside with lightening protection devices
(e.g. lightening conductors).
Take lightening protection measures which mitigate the effects of
lightning strikes.
