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.

Only connect or disconnect lines when power is safely isolated!
The lines to the device can carry hazardous voltages and currents. Contact with
the lines when live can result in severe injury or death. Therefore, read and
observe the following safety rules before you perform work on the device:
1. Disconnect the respective system component from the power supply.
2. Secure the system component against unintentional restart.
3. Check if the voltage is positively isolated.

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.

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.

Perform insulation tests with direct current (DC)!
Both the supply voltage and control voltage side are capacitively coupled to the
DIN rail. If the modules are mounted on the DIN rail, application of an AC
voltage between the two potentials can lead to the destruction of the device.
Use only direct current (DC) for insulation testing.
To avoid destroying the device, discharge the device completely before applying
the test voltage again.

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 standard fieldbus couplers/controllers 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 I/O
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 exchanges process data with the respective control
via the respective fieldbus. The programmable fieldbus controllers (PFC) allow
implementation of additional PLC functions. WAGO-I/O-PRO is used to program
the fieldbus controllers according to 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 an internal
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.

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.

3.2 Component Update
For the case of an update of one component, the lateral marking on each
component contains a prepared matrix.
This matrix makes columns available for altogether three updates to the entry of
the current update data, like production order number (NO), update date (DS),
software version (SW), hardware version (HW) and the firmware loader version
(FWL, if available).

If the update of a component took place, the current version data are registered
into the columns of the matrix.
Additionally with the update of a fieldbus coupler or controller also the cover of
the configuration and programming interface of the fieldbus coupler or fieldbus
controller is printed on with the current manufacturing and production order
number.
The original manufacturing data on the housing of the component remain thereby.

3.3 Storage, Assembly and Transport
Whenever possible, the components are to be stored in their original packaging.
Likewise, the original packaging provides optimal protection during transport.
When assembling or repacking the components, the contacts must not be soiled or
damaged. The components must be stored and transported in appropriate
containers/packaging. Thereby, the ESD information is to be regarded.
