Note
How to connect the DIQ/S 182-MOD to the Modbus master is
described in detail in the chapter 7 M
ODBUS CONNECTION .
3.1 Scope of delivery
The following parts are included in the scope of delivery of the DIQ/
S 182-MOD:
 DIQ/S 182-MOD Universal Transmitter
 Accessory kit with:
– Contact carrier with screws
– ISO cap nuts with screws and ring washers
– Cable glands with sealing gaskets
 Operating manual.
3.2 Requirements of the measurement location
The measurement location must meet the environmental conditions
specified in section 10.1 DIQ/S 182-MOD.
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 10 T
ECHNICAL DATA ).
