Mounting Instructions
The surge arrester Air Lancer Surge Protect is a vital component for providing
lightning protection to the interior electronics of WLAN systems that are
connected to outdoor antennas. Whatever the circumstances, the deployment of
the Air Lancer Surge Protect is essential – despite outdoor lightning-
protection measures, partial discharges can still give rise to overvoltage
that can damage sensitive WLAN modules. The Air Lancer Surge Protect is always
mounted between the access point and the antenna, preferably as near as
possible to the access point.
In addition to this, an Air Lancer Extender SN-LAN surge arrester can also be
used to reduce possible surges in the Ethernet or PoE cable.
Connectors of the Air Lancer Surge Protect
The Air Lancer Surge Protect has two connectors and is positioned between the
access point and the antenna:
- N-jack for connection to the antenna (unprotected section)
- N-plug for connection to the access point (protected section)
- Connection for grounding cable
Connecting to the access point
Connect the Surge Protect to an access point by connecting the protected
section of the SurgeProtect directly to the antenna connector of the access
point.
- The Air Lancer AN-RPSMA-NJ adapter (available as an accessory) can be used to connect to LANCOM indoor access points.
- When mounting the access point outdoors, ensure that the screw connections are water-proof. A secure seal will be provided 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 as long/short as needed) to the N-jack of the
AirLancer Surge Protect. Then connect the other end of the antenna cable to
the antenna itself.
- 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 provi-ded by teflon tape or self-vulcanizing tape, for instance.
Grounding the AirLancer SurgeProtect
The mounting of the AirLancer SurgeProtect must be sufficiently grounded so
that any overvoltages can be conducted away to the building’s earthing system.
To earth the AirLancer SurgeProtect, connect the earthing ring and cable lug
supplied to a suitable earth cable. Earthing can be implemented as follows
depending on the application:
- For access points installed indoors, the potential load is equalized via the building’s grounding line by PE cable (protective-earth cable, min. 4 mm² Cu).
- For an access point mounted outdoors, its ground and the ground of the AirLancer SurgeProtect are connected via the protective-earth cable (min. 6 mm² Cu) of the pole or of the antenna, e.g. via the antenna mounting clamps.
