2.1.2 Personnel Qualifications
All sequences implemented on WAGO-I/O-SYSTEM 750 devices may only be
carried out by electrical specialists with sufficient knowledge in automation. The
specialists must be familiar with the current norms and guidelines for the devices
and automated environments.
All changes to the coupler or controller should always be carried out by qualified
personnel with sufficient skills in PLC programming.

2.1.3 Use of the WAGO-I/O-SYSTEM 750 in Compliance with
Underlying Provisions
Fieldbus couplers, fieldbus controllers and I/O modules found in the modular
WAGO-I/O-SYSTEM 750 receive digital and analog signals from sensors and
transmit them to actuators or higher-level control systems. Using programmable
controllers, the signals can also be (pre-) processed.
The devices have been developed for use in an environment that meets the IP20
protection class criteria. Protection against finger injury and solid impurities up to
12.5 mm diameter is assured; protection against water damage is not ensured.
Unless otherwise specified, operation of the devices in wet and dusty
environments is prohibited.
Operating the WAGO-I/O-SYSTEM 750 devices in home applications without
further measures is only permitted if they meet the emission limits (emissions of
interference) according to EN 61000-6-3. You will find the relevant information
in the section “Device Description” > “Standards and Guidelines” in the manual
for the used fieldbus coupler/controller.
Appropriate housing (per 2014/34/EU) is required when operating the WAGO-
I/O-SYSTEM 750 in hazardous environments. Please note that a prototype test

install the system and its components exclusively in appropriate housings,
cabinets or in electrical operation rooms. Allow access to such equipment and
fixtures to authorized, qualified staff only by means of specific keys or tools.

Protect the components against materials having seeping and insulating
properties!
The components are not resistant to materials having seeping and insulating
properties such as: aerosols, silicones and triglycerides (found in some hand
creams). If you cannot exclude that such materials will appear in the component
environment, then install the components in an enclosure being resistant to the
above-mentioned materials. Clean tools and materials are imperative for handling
devices/modules.

The Analog Input Module 750-481/003-000 (2AI RTD Ex i) processes signals
from resistance sensors that are operating in hazardous environments of Zones 0
and 1. Resistance thermometers (RTD), as well as resistors and potentiometers can be
connected.
Depending on the operating mode, the resistance value is converted to a
temperature or directly sent out by the module. A microprocessor within the
module is used for converting and linearizing the measured resistance value into a
numeric value proportional to the temperature of the selected resistance sensor.
