4.3.1
Safety
The installation must comply with EN 60728-11 (Cabled distribution systems standard -
Security).
Earthing is a key parameter for a secure installation.
Earthing of the installation is mandatory for:
-
Indoor installation parts: mains supply, PoE injector
-
Outdoor installation parts: tower, pole, Wirnet iBTS mounting kit, antennas.
Note:
none of the earthing cables required for the installation are provided by KERLINK.
A second key parameter for a secure installation is the lighting protection.
In its standard configuration, the Wirnet iBTS is provided with nominal internal surge
protections. The Wirnet iBTS gateways are not warranted by KERLINK in case of
deterioration due to lighting. Additional surge protections are recommended in harsh
environments.
A lighting rod with a down conductor to earth is strongly recommended in most of the
applications to avoid direct impacts on the aerials (antennas and Wirnet iBTS).
The following picture describes all the required cables connections required for the
installation, including power supply cables, data cables, RF coaxial cables and earthing
connections.
