Manual
Version 1.1.0, valid from FW Version 03.08.07(20)
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 GmbH & Co. KG reserves the right to provide for any alterations or
modifications. WAGO 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 Compact 751 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 Intended Use
Controllers of the modular WAGO I/O System Compact 751 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.
This product fulfills the requirements of protection type IP20 and is designed for
use in dry interior spaces. There is protection against finger injury and solid
impurities up to 12.5 mm diameter is assured; protection against water damage is
not ensured.
The product represents an open-type device. It may only be installed in
enclosures (tool-secured enclosures or operating rooms) which fulfil the listed
requirements specified in the safety instructions in chapter “Safety Advice
(Precautions)”. Use without additional protective measures in environments within
which dust, corrosive fumes, gases or ionized radiation can occur is considered
improper use.
The product is intended for installation in automation systems. It does not have
its own integrated separator. A suitable separator must therefore be created on
the plant side.

EN 61000-6-3. Please observe the installation regulations!
You will find the relevant information in the section “Device Description” >
“Standards and Guidelines” in the manual for the used product.
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 GmbH
& Co. KG:

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 device in only one suitable enclosure!
The device is an open system. Install the device in a suitable enclosure. This
enclosure must:
• Guarantee that the max. permissible degree of pollution is not exceeded.
• Offer adequate protection against contact.
• Prevent fire from spreading outside of the enclosure.
• Offer adequate protection against UV irradiation.
• Guarantee mechanical stability
• Restrict access to authorized personnel and may only be opened with tools
Ensure disconnect and overcurrent protection!
The device is intended for installation in automation technology systems.
Disconnect protection is not integrated. Connected systems must be protected by
a fuse.
Provide suitable disconnect and overcurrent protection on the system side!
Ensure a standard connection!
To minimize any hazardous situations resulting in personal injury or to avoid
failures in your system, the data and power supply lines shall be installed
according to standards, with careful attention given to ensuring the correct
terminal assignment. Always adhere to the EMC directives applicable to your
application.

Power from SELV/PELV power supply only!
All field signals and field supplies connected to the controller „Compact Controller
100“ (751-9301) must be powered from SELV/PELV power supply(s)!
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.
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.
Do not use in telecommunication circuits!
Only use devices equipped with ETHERNET or RJ-45 connectors in LANs.
Never connect these devices with telecommunication networks.

2.4 Special Use Conditions for ETHERNET Devices
If not otherwise specified, ETHERNET devices are intended for use on local
networks. Please note the following when using ETHERNET devices in your
system:
• Do not connect control components and control networks directly to an
open network such as the Internet or an office network. WAGO
recommends putting control components and control networks behind a
firewall.
• In the control components (e.g., for WAGO I/-CHECK and CODESYS)
close all ports and services not required by your application to minimize the
risk of cyber attacks and to enhance cyber security.
Only open ports and services during commissioning and/or configuration.
• Limit physical and electronic access to all automation components to
authorized personnel only.
• Change the default passwords before first use! This will reduce the risk of
unauthorized access to your system.
• Regularly change the passwords used! This will reduce the risk of
unauthorized access to your system.
• If remote access to control components and control networks is required,
use a Virtual Private Network (VPN).
• Regularly perform threat analyses. You can check whether the measures
taken meet your security requirements.
• Use “defense-in-depth” mechanisms in your system's security configuration
to restrict the access to and control of individual products and networks.
• Please note the risks of using cloud services!
If you use third-party cloud services, sensitive data is transferred to the
cloud service provider at one's own responsibility. External access may
result in manipulated data and/or unwanted control commands affecting the
performance of your control system.
Use encryption methods to protect your data and observe the information
provided by the Federal Office for Information Security – “Cloud: Risks and
Security Tips”.
Observe comparable publications of the competent, public institutions of
your country.
