750-471 4AI U/I Diff Galv
Manual
Version 1.0.0
2 Important Notes
This section includes an overall summary of the most important safety
requirements and notes that are mentioned in each individual section. To protect
your health and prevent damage to devices as well, it is imperative to read and
carefully follow the safety guidelines.
2.1 Legal Bases
2.1.1 Subject to Changes
WAGO Kontakttechnik GmbH & Co. KG reserves the right to provide for any
alterations or modifications. WAGO Kontakttechnik GmbH & Co. KG owns all
rights arising from the granting of patents or from the legal protection of utility
patents. Third-party products are always mentioned without any reference to
patent rights. Thus, the existence of such rights cannot be excluded.
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

12 Important Notes WAGO-I/O-SYSTEM 750
750-471 4AI U/I Diff Galv
Manual
Version 1.0.0
prototype test certificate must be obtained that confirms the correct installation of
the system in a housing or switch cabinet.
The implementation of safety functions such as EMERGENCY STOP or safety
door monitoring must only be performed by the F-I/O modules within the modular
WAGO-I/O-SYSTEM 750. Only these safe F-I/O modules ensure functional
safety in accordance with the latest international standards. WAGO's
interference-free output modules can be controlled by the safety function.
2.1.4 Technical Condition of Specified Devices
The devices to be supplied ex works are equipped with hardware and software
configurations, which meet the individual application requirements. These
modules contain no parts that can be serviced or repaired by the user. The
following actions will result in the exclusion of liability on the part of WAGO
Kontakttechnik GmbH & Co. KG:
•Repairs,
•Changes to the hardware or software that are not described in the
operating instructions,
•Improper use of the components.
Further details are given in the contractual agreements. Please send your
request for modified and new hardware or software configurations directly to
WAGO Kontakttechnik GmbH & Co. KG.
2.1.4.1 Disposal
Recycle metals, plastics and packaging materials.
Automation components used in the professional sector (B2B) must be properly
disposed of once no longer in use in accordance with the respective national
guidelines (e.g., European Community Directive WEEE 2012/19/EU).
Packaging of all types must be disposed of in such a way that a high level of
recovery, reuse and recycling is possible. PPWD 94/62/EU and 2004/12/EU
packaging guidelines apply throughout Europe.

Manual
Version 1.0.0
2.2 Safety Advice (Precautions)
For installing and operating purposes of the relevant device to your system the
following safety precautions shall be observed:
Do not work on devices while energized!
All power sources to the device shall be switched off prior to performing any
installation, repair or maintenance work.
Install the device only in appropriate housings, cabinets or in electrical
operation rooms!
The WAGO-I/O-SYSTEM 750 and its components are an open system. As such,
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.
Power from SELV/PELV power supply only!
All field signals and field supplies connected to this I/O module (750-471) must
be powered from SELV/PELV power supply(s)!
Replace defective or damaged devices!
Replace defective or damaged device/module (e.g., in the event of deformed
contacts), since the long-term functionality of device/module involved can no
longer be ensured.
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.

14 Important Notes WAGO-I/O-SYSTEM 750
750-471 4AI U/I Diff Galv
Manual
Version 1.0.0
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.

750-471 4AI U/I Diff Galv
Manual
Version 1.0.0
3 Device Description
The 750-471 I/O Module 750-471 (4AI U/I Diff Galv) processes differential current
and voltage signals from the field:
•0 … 10 V
•± 10 V
•± 200 mV
•0 … 20 mA
•3,6 … 21 mA NE43
•4 … 20 mA
•± 20 mA
The I/O module has four electrically isolated input channels for differential
signals. The sensors are connected to the CAGE CLAMP® terminals +AI1 and
−AI1, +AI2 and −AI2, +AI3 and −AI3, +AI4 and −AI4.
The assignment of the connections is described in the “Connectors” section.
Connection examples are shown in section “Connect Devices” > … >
“Connection Example(s)”.
The input signal is electrically isolated and transmitted with a resolution of 16 bits.
The operational readiness and the trouble-free local bus communication of the
channels are indicated via a green function LED.
A red fault LED per channel indicates that the signal is outside the measuring
range and depending on the type of signal additionally an overload or a wire
break.
Details about the individual signal types are described in the “Process Image” >
“Process Data” section.
With consideration of the power jumper contacts, the individual modules can be
arranged in any combination when configuring the fieldbus node.
An arrangement in groups within the group of potentials is not necessary.
Power to the internal electronics is supplied via internal data bus.
The 750-471 module can be used with the fieldbus couplers and controllers of
the WAGO-I/O-SYSTEM 750 of the specified version or higher listed in the
“Compatibility list” table.
