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. 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. 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.

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 soiled contacts using oil-free compressed air or with ethyl alcohol and leather cloths. 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 /-3. When handling the devices, please ensure that environmental factors (personnel, work space and packaging) are properly grounded.

The reliable positioning and connection is made using a tongue and groove system. Due to the automatic locking, the individual devices are securely seated on the rail after installation. Starting with the fieldbus coupler/controller, the I/O modules are mounted adjacent to each other according to the project design. Errors in the design of the node in terms of the potential groups (connection via the power contacts) are recognized, as the I/O modules with power contacts (blade contacts) cannot be linked to I/O modules with fewer power contacts. Risk of injury due to sharp-edged blade contacts! The blade contacts are sharp-edged. Handle the I/O module carefully to prevent injury. Insert I/O modules only from the proper direction! All I/O modules feature grooves for power jumper contacts on the right side. For some I/O modules, the grooves are closed on the top. Therefore, I/O modules featuring a power jumper contact on the left side cannot be snapped from the top. This mechanical coding helps to avoid configuration errors, which may destroy the I/O modules. Therefore, insert I/O modules only from the right and from the top. Don't forget the bus end module! Always plug a bus end module onto the end of the fieldbus node! You must always use a bus end module at all fieldbus nodes with WAGO-I/O- SYSTEM 750 fieldbus couplers/controllers to guarantee proper data transfer.

If more than one conductor must be routed to one connection, these must be connected in an up-circuit wiring assembly, for example using WAGO feedthrough terminals.

Very often, these transients exceed the permissible limits specified in the EMC standards. They must therefore be limited by using external protective circuits. Furthermore, they cause an arc, which may destroy the switching contact, and has a significant impact on the lifetime and safety of the relay. The following protective circuits, which are directly connected to the source of the interference in parallel with the consumer, have proved successful in practice: Table 14: Protective Circuits for Contacts of Relay Modules Protective Circuits Additional Off-Delay Figure 15: Diode Figure 16: Zener Diode and Diode Figure 17: Suppressor Diode Figure 18: Varistor Defined Induction Voltage Limitation Bipolar Effective Attenuation long yes (U D ) no medium to short medium to short medium to short yes (U ZD ) yes (U ZD ) yes (U VDR ) no yes yes Advantages and Disadvantages Advantages: easy implementation cost-effective and reliable uncritical dimensioning low induction voltages Disadvantages: attenuation only via load resistor long off-delay Advantages: uncritical dimensioning Disadvantages: attenuation only above U ZD Advantages: cost-effective uncritical dimensioning limitation of positive and negative peaks suitable for AC voltage Disadvantages: attenuation only above U ZD Advantages: high power absorption uncritical dimensioning suitable for AC voltage Disadvantages: attenuation only above U VDR
