2.1.3. Lightening Protection
Warning: Never install the equipment during stormy weather and lightening.
WipLL devices comply with the Surge Immunity standard: EN 61000-4-5.
WipLL devices are protected from lightening surges as the outdoor devices (BSRs
and SPRs) are encased in a plastic chassis. Therefore, if lightening strikes the
device, an electrical circuit cannot be completed, and hence, no electrical surge can
occur.
In addition, WipLL outdoor and indoor (SDA) devices provide high-speed data line
protection against direct and induced transient over-voltages surges on the cables.
This capability is provided by the fact that all WipLL devices are designed with
TVS (transient voltage suppressor) components that maintain potential differences.
However, for geographical areas that have above normal lightening activity, Airspan
can supply a surge protector composed of a 15-pin D-type adapter with a grounding
wire.
