2 Safety
2.1 Intended Use
The WAGO-I/O-SYSTEM 750 is used to receive digital and analog signals from sensors and output them to actuators.
The WAGO-I/O-SYSTEM 750 and the assembled I/O modules were developed for a working environment that
complies with the IP20 degree of protection. It is equipped with a finger guard and protection against solid foreign
objects ≥ 12.5mm; however it is not protected against water.
In order to operate the product in potentially explosive atmospheres, corresponding enclosure protection is required in
accordance with the Directive 2014/34/EU. Furthermore, please note that a type examination certificate must be
obtained that confirms the correct installation of the system in the enclosure or switch cabinet.
The product is designed for indoor use only.
Use SMA products only in accordance with the information provided in the enclosed documentation and with the
locally applicable laws, regulations, standards and directives. Any other application may cause personal injury or
property damage.
Alterations to the SMA products, e.g., changes or modifications, are only permitted with the express written permission
of SMA Solar Technology AG. Unauthorized alterations will void guarantee and warranty claims and in most cases
terminate the operating license. SMA Solar Technology AG shall not be held liable for any damage caused by such
changes.
Any use of the product other than that described in the Intended Use section does not qualify as the intended use.
The enclosed documentation is an integral part of this product. Keep the documentation in a convenient, dry place for
future reference and observe all instructions contained therein.
This document does not replace and is not intended to replace any local, state, provincial, federal or national laws,
regulations or codes applicable to the installation, electrical safety and use of the product. SMA Solar Technology AG
assumes no responsibility for the compliance or non-compliance with such laws or codes in connection with the
installation of the product.
The type label must remain permanently attached to the product.
2.2 IMPORTANT SAFETY INSTRUCTIONS
SAVE THESE INSTRUCTIONS
This section contains safety information that must be observed at all times when working.
The product has been designed and tested in accordance with international safety requirements. As with all electrical
or electronical devices, there are residual risks despite careful construction. To prevent personal injury and property
damage and to ensure long-term operation of the product, read this section carefully and observe all safety
information at all times.
DANGER
Danger to life due to electric shock when live components or cables are touched
High voltages are present in the conductive components or cables of the product. Touching live parts and cables
results in death or lethal injuries due to electric shock.
• Do not touch non-insulated parts or cables.
• Disconnect the product from voltage sources and make sure it cannot be reconnected before working on the
device.
• Observe the prescribed minimum clearance between the network cable and live installation components, or
use suitable insulation.
• Observe all safety information on components associated with the product.
• Wear suitable personal protective equipment for all work on the product.
• Always perform all work in accordance with the locally applicable standards, directives and laws.

2 Safety SMA Solar Technology AG
Installation ManualEDMM-WAGO-IO-IA-en-118
NOTICE
Damage to the product due to condensation
If the product is moved from a cold environment to a warm environment, condensation may form in the product. This
can damage the product or impair its functionality.
• When there are large temperature differences, wait until the product has reached room temperature to connect
the voltage supply.
• Make sure the product is dry.
NOTICE
Damage to electronic components due to electrostatic discharge
Electrostatic discharge can damage or destroy electronic components.
• Observe the ESD safety regulations when working on the product.
• Wear suitable personal protective equipment for all work on the product.
• Discharge electrostatic charge by touching grounded elements. Only then is it safe to touch electronic
components.
NOTICE
Damage to the product due to cleaning agents
The use of cleaning agents may cause damage to the product and its components.
• Clean the product and any dirty contacts on the product with Propanol.
• Do not treat dirty contacts on the product with contact cleaners.
DHCP Server is recommended.
The DCHP server automatically assigns the appropriate network settings to your nodes in the local network. A
manual network configuration is therefore not necessary. In a local network, the Internet router is usually the
DHCP server. If the IP addresses in the local network are to be assigned dynamically, DHCP must be activated in
the Internet router (see the Internet router manual). In order to receive the same IP address by the internet router
after a restart, set the MAC address binding.
In networks where no DHCP server is active, proper IP addresses must be assigned from the free address pool of
the network segment to all network participants to be integrated during commissioning.

Installation Manual 9EDMM-WAGO-IO-IA-en-11
Use of Ethernet devices
Please observe the following information if you use Ethernet devices in your system:
• Do not connect the control components and control networks with an open network such as the Internet.
Always install control components and control networks behind a firewall.
• Restrict physical and electronic access to all automation components to a group of authorized persons.
• Be sure to change any automatically generated passwords before initial commissioning. This will reduce the
risk of unauthorized persons gaining access to your system.
• Regularly change your passwords. This will reduce the risk of unauthorized persons gaining access to your
system.
• If remote access to control components and control networks is required, use a virtual private network (VPN)
whenever possible.
• Carry out regular threat assessments. This will allow you to make sure that the measures in place match your
protection needs.
• When it comes to the safety-oriented design of your system, use defense in depth mechanisms to restrict
access to and control of individual products and networks.
