2.1.3 Use of the 750 Series in Compliance with Underlying
Provisions
Fieldbus couplers, 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 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 or controller.

Power from SELV/PELV power supply only!
All field signals and field supplies connected to this XTR fieldbus
coupler/controller (750-333/040-000) must be powered from SELV/PELV power
supply(s)!
Do not touch hot surfaces!
The surface of the housing can become hot during operation. If the device was
operated at high ambient temperatures, allow it to cool off before touching it.
Ensure proper contact with the DIN-rail!
Proper electrical contact between the DIN-rail and device is necessary to
maintain the EMC characteristics and function of the device.
Replace defective or damaged devices!
Replace defective or damaged device/module (e.g., in the event of deformed
contacts).
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.
Clean only with permitted materials!
Clean housing and soiled contacts with propanol.

Do not use any contact spray!
Do not use any contact spray. The spray may impair contact area functionality in
connection with contamination.
Do not reverse the polarity of connection lines!
Avoid reverse polarity of data and power supply lines, as this may damage the
devices involved.
Avoid electrostatic discharge!
The devices are equipped with electronic components that may be destroyed by
electrostatic discharge when touched. Please observe the safety precautions
against electrostatic discharge per DIN EN 61340-5-1/-3. When handling the
devices, please ensure that environmental factors (personnel, work space and
packaging) are properly grounded.
Use only direct current (DC) for insulation testing!
Both the system voltage and field voltage side are capacitively coupled to the
DIN-rail. If an I/O module is mounted on the DIN-rail, application of an AC voltage
between the DIN-rail and at least one of these two potentials can lead to the
destruction of the module.
Use only direct current (DC) for insulation testing. To avoid destroying the I/O
module, you must discharge it completely before applying the test voltage again.

3 System Description
The 750 XTR Series is part of the WAGO I/O SYSTEM 750.
The WAGO I/O SYSTEM 750 is a modular, fieldbus-independent input/output
system (I/O system). The configuration described here consists of a fieldbus
coupler/controller (1) and the modular I/O modules (2) for any signal shapes that
form the fieldbus node together. The end module (3) completes the node and is
required for correct operation of the fieldbus node.
Figure 1: Fieldbus Node (Example)
Fieldbus couplers/controllers are available for different fieldbus systems.
The extended ECO fieldbus couplers contain the fieldbus interface, electronics
and a power supply terminal. The fieldbus interface forms the physical interface
to the relevant fieldbus. The electronics process the data of the bus modules and
make it available for the fieldbus communication. The 24 V system supply and
the 24 V field supply are fed in via the integrated power supply terminal.
The fieldbus coupler/controller communicates via the relevant fieldbus. The
programmable fieldbus controller (PFC) enables the implementation of additional
PLC functions. Programming is done with the WAGO-I/O-PRO in accordance
with IEC 61131-3.
I/O modules for diverse digital and analog I/O signals as well as special functions
can be connected to the fieldbus coupler/controller. The communication between
the fieldbus coupler/controller and the I/O modules is carried out via a local bus.
The components of the WAGO I/O SYSTEM 750 have clear termination points,
light emitting diodes for status display, plug-in mini WSB tags and group marker
cards for labeling.
The 1, 2 or 3 wire technology supplemented by a ground wire connection allows
for direct sensor or actuator wiring.

Version 1.4.0
The distinctiveness of the 750 XTR Series lies in its area of application in
extreme environmental conditions. It is extremely temperature-resistant, immune
to interference, as well as insensitive to vibrations and impulse voltages.
The components of the 750 XTR Series are easily recognizable by their dark-
gray housing color.
