3.3 Installation guidelines for lightning protection
When using the IQ S
ENSOR

ET
instrumentation, particularly in outdoor
areas, adequate protection against (electrical) surges must be
provided. A surge is a summation phenomenon of surge voltage and
surge current. It is generated through the indirect effect of a lightning
event or switching operation in the mains, in the grounding system and
in information technology lines.
To be adequately protected against the damaging effects of surges, an
integrated concept of the following protective measures is required:

internal device-related protective measures and

external protective measures of the installation environment.
The internal device-related protective measures are already integrated
in the WTW online measuring technology as so-called 'lightning
protection' (see chapter 10 T
ECHNICAL DATA
).
