The overvoltage adapter AirLancer Extender SA-5L is the central com-
ponent for protecting the interior electronics of WLAN systems with out-
door antennas. The employment of the AirLancer Extender SA-5L is
essential under all circumstances
—despite outer lightning-protec-
tion measures, partial discharges can still give rise to overvoltage that
can damage sensitive WLAN modules. The AirLancer Extender SA-5L is
always mounted between the Access Point and the antenna, preferably
as near as possible to the Access Point.
Additionally, the AirLancer Extender SA-LAN overvoltage adapter can
be employed to counter potential overvoltage from the Ethernet or PoE
cable.
Further information on lighting and overvoltage protection for
outdoor WLAN systems can be found in the WLAN Outdoor
Guide, available as a download from www.lancom.de.
AirLancer Extender SA-5L connectors
The AirLancer Extender SA-5L has two connectors for connecting to the
Access Point and the antenna:
쐃
N connector for connection to the antenna (unprotected area)
쐇
N socket for connection to the Access Point (protected end marked
in red)
Connecting to the Access Point
For connection to an Access Point, you first connect the end of the
adapter cable (supplied with the antenna) to the N connector of the
AirLancer Extender SA-5L. Then connect the other end of the adapter
cable to the Access Point's antenna output.
Depending on the model, the AirLancer Extender SA-5L can
also be connected directly to the antenna output of the Access
Point, and in this case no adapter cable is necessary.
When mounting the Access Point outdoors, ensure that the
screw connections are waterproof. A secure seal will be provi-
ded by teflon tape or self-vulcanizing tape, for instance.
Connecting to the antenna
For connection to the antenna, first connect the end of the antenna
cable (making sure that this is long enough) to the N socket of the
AirLancer Extender SA-5L. Then connect the other end of the antenna
cable to the antenna's input.
You may require an adapter or adapter cable depending on the
type of connector.
When connecting the antenna, ensure that all connections to
the antenna are water-resistant screw connectors. A secure seal
will be provided by teflon tape or self-vulcanizing tape, for
instance.
Earthing the AirLancer Extender SA- 5L
The mounting of the AirLancer Extender SA-5L must be sufficiently
earthed in order for any overvoltages can be conducted away to the
building's earthing system.
To earth the AirLancer Extender SA-5L, a cable lug should be fixed with
a nut to the protected side of the overvoltage adapter. Earthing can be
implemented as follows depending on the application:
쮿
For an Access Point mounted indoors, potential equalization is con-
ducted via the building's earthing system with the aid of a PE lead
(Protected Earth, 1.5 mm² Cu).
쮿
For an Access Point mounted outdoors, its earth and the earth of the
AirLancer Extender SA-5L are connected via the potential-equaliza-
tion lead (16 mm² Cu) of the mast or of the antenna, e.g. via the
antenna mounting clamps.
