3.2 Requirements of the measurement location
The measurement location must meet the environmental conditions
specified in section 9.1 IQ S
ENSOR N ET .
3.3 Installation guidelines for lightning protection
When using the IQ S ENSOR N 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 YSI online measuring technology as so-called 'lightning
protection' (see chapter 9 T
ECHNICAL DATA ).
The external protective measures of the installation environment can
be carried out with respect to the following guidelines:
1 All lines of the IQ S ENSOR N ET system must be
a) installed inside (or else close to) the grounded metallic mounting
constructions, e.g. handrails, pipes and posts if possible
