2.3.2. Grounding
Only certain ASWipLL devices require additional grounding. ASWipLL devices
that do not require additional grounding provide grounding at the main electrical
outlet. The following table lists the ASWipLL devices' grounding requirements.
Table 2-1: ASWipLL grounding requirements
Site ASWipLL device Grounding
BSR/PPR Through the mains (via BSDU), i.e. no additional
grounding required
BSDU Additional grounding required (grounding lug at rear
end of chassis)
Base Station
BSPS (third-party) Additional grounding required (grounding lug at rear
end of chassis)
SPR Through the mains (via SDA), i.e. no additional
grounding required CPE
IDR Through the mains, i.e. no additional grounding
required
2.3.3. Lightning Protection
Warning: Never install the equipment during stormy weather or lightning.
ASWipLL devices comply with the Surge Immunity standard: EN 61000-4-5 .
ASWipLL devices are protected from lightning surges as the outdoor devices (BSRs
and SPRs) are encased in a plastic covering. Therefore, if lightning strikes the
device, an electrical circuit cannot be completed, and hence, no electrical surge can
occur.
In addition, ASWipLL outdoor and indoor (i.e. SDA) devices provide high-speed
data line protection against direct and induced transient over-voltage surges on the
cables. This capability is provided by the fact that all ASWipLL devices are
designed with transient voltage suppressor (TVS) components that maintain
potential differences.
