1.4 Safety Information
When connecting the device to your installation and during operation, the fol­lowing safety notes must be observed:
Danger The WAGO-I/O-SYSTEM 750 and its components are an open system. It must only be assembled in housings, cabinets or in electrical operation rooms. Access is only permitted via a key or tool to authorized qualified per­sonnel.
Danger All power sources to the device must always be switched off before carrying out any installation, repair or maintenance work.
Warning
Replace defective or damaged device/module (e.g. in the event of deformed contacts), as the functionality of fieldbus station in question can no longer be ensured on a long-term basis.
Warning
The components are not resistant against materials having seeping and insu­lating properties. Belonging to this group of materials is: e.g. aerosols, sili­cones, triglycerides (found in some hand creams). If it cannot be ruled out that these materials appear in the component environment, then the compo­nents must be installed in an enclosure that is resistant against the above men­tioned materials.

12 • The WAGO-I/O-SYSTEM 750 System Description

2 The WAGO-I/O-SYSTEM 750
2.1 System Description
The WAGO-I/O-SYSTEM 750 is a modular, fieldbus independent I/O system. In this description, it is comprised of an ECO fieldbus coupler (1) and up to 64 connected fieldbus modules (2) for any type of signal. Together, these make up the fieldbus node. The end module (3) completes the node.
Fig. 2-1: Fieldbus node g0xxx14x
ECO Couplers for fieldbus systems such as PROFIBUS, INTERBUS, CANopen and DeviceNet are available.
The ECO coupler contains the fieldbus interface, electronics and a power sup­ply for the system. The fieldbus interface forms the physical interface to the relevant fieldbus. The electronics process the data of the bus modules and make it available for the fieldbus communication. The 24 V system supply is fed in via the voltage supply.
The ECO coupler is primarily conceived for applications with digital I/O func­tions. In addition, modules for most different digital and analog I/O functions as well as special functions can be connected to the ECO coupler. The com­munication between the ECO coupler and the bus modules is carried out via an internal bus.
The WAGO-I/O-SYSTEM 750 has a clear port level with LEDs for status in­dication, insertable mini WSB markers and pullout group marker carriers. The 3-wire technology supplemented by a ground wire connection allows for direct sensor/actuator wiring.

2.6.3 Assembly onto Carrier Rail
2.6.3.1 Carrier rail properties
All system components can be snapped directly onto a carrier rail in accor­dance with the European standard EN 50022 (DIN 35).
Warning WAGO supplies standardized carrier rails that are optimal for use with the I/O system. If other carrier rails are used, then a technical inspection and ap­proval of the rail by WAGO Kontakttechnik GmbH should take place.
Carrier rails have different mechanical and electrical properties. For the opti­mal system setup on a carrier rail, certain guidelines must be observed:
• The material must be non-corrosive.
• Most components have a contact to the carrier rail to ground electro-
magnetic disturbances. In order to avoid corrosion, this tin-plated carrier rail contact must not form a galvanic cell with the material of the carrier rail which generates a differential voltage above 0.5 V (saline solution of
0.3% at 20°C) .
• The carrier rail must optimally support the EMC measures integrated into the system and the shielding of the bus module connections.
• A sufficiently stable carrier rail should be selected and, if necessary, sev­eral mounting points (every 20 cm) should be used in order to prevent bending and twisting (torsion).
• The geometry of the carrier rail must not be altered in order to secure the safe hold of the components. In particular, when shortening or mounting the carrier rail, it must not be crushed or bent.
• The base of the I/O components extends into the profile of the carrier rail. For carrier rails with a height of 7.5 mm, mounting points are to be riveted under the node in the carrier rail (slotted head captive screws or blind riv­ets).

2.6.4 Spacing
The spacing between adjacent components, cable conduits, casing and frame sides must be maintained for the complete field bus node.
Fig. 2-4: Spacing g01xx13x
The spacing creates room for heat transfer, installation or wiring. The spacing to cable conduits also prevents conducted electromagnetic interferences from influencing the operation.

2.6.5 Plugging and Removal of the Components
Warning Before work is done on the components, the voltage supply must be turned off.
In order to safeguard the ECO coupler from jamming, it should be fixed onto the carrier rail with the locking disc. To do so, push on the upper groove of the locking disc using a screwdriver.
To pull out the ECO fieldbus coupler, release the locking disc by pressing on the bottom groove with a screwdriver and then pulling the orange colored unlocking lug.
Fig. 2-5: Coupler and unlocking lug g0xxx18e
It is also possible to release an individual I/O module from the unit by pulling an unlocking lug.

2.6.6 Assembly Sequence
All system components can be snapped directly on a carrier rail in accordance with the European standard EN 50022 (DIN 35).
The reliable positioning and connection is made using a tongue and groove system. Due to the automatic locking, the individual components are securely seated on the rail after installing.
Starting with the ECO coupler, the bus modules are assembled adjacent to each other according to the project planning. Errors in the planning of the node in terms of the potential groups (connection via the power contacts) are recog­nized, as the bus modules with power contacts (male contacts) cannot be linked to bus modules with fewer power contacts.
Attention Always link the bus modules with the ECO coupler, and always plug from above.
Warning Never plug bus modules from the direction of the end terminal. A ground wire power contact, which is inserted into a terminal without contacts, e.g. a 4-channel digital input module, has a decreased air and creepage distance to the neighboring contact in the example DI4.
Always terminate the fieldbus node with an end module (750-600).

2.6.7 Internal Bus / Data Contacts
Communication between the ECO coupler and the bus modules as well as the system supply of the bus modules is carried out via the internal bus. It is com­prised of 6 data contacts, which are available as self-cleaning gold spring con­tacts.
Fig. 2-7: Data contacts p0xxx07x
Warning Do not touch the gold spring contacts on the I/O modules in order to avoid soiling or scratching!
ESD (Electrostatic Discharge) The modules are equipped with electronic components that may be destroyed by electrostatic discharge. When handling the modules, ensure that the envi­ronment (persons, workplace and packing) is well grounded. Avoid touching conductive components, e.g. gold contacts.

2.6.8 Power Contacts
Self-cleaning power contacts , are situated on the side of some components which further conduct the supply voltage for the field side. These contacts come as touchproof spring contacts on the right side of the bus modules. As fitting counterparts the module has male contacts on the left side.
Danger The power contacts are sharp-edged. Handle the module carefully to prevent injury.
Attention Please take into consideration that some bus modules have no or only a few power jumper contacts. The design of some modules does not allow them to be physically assembled in rows, as the grooves for the male contacts are closed at the top.

2.6.9 Wire connection
All components have CAGE CLAMP® connections. The WAGO CAGE CLAMP® connection is appropriate for solid, stranded
and fine–stranded conductors. Each clamping unit accommodates one conduc­tor.
Fig. 2-9: CAGE CLAMP® Connection g0xxx08x
The operating tool is inserted into the opening above the connection. This opens the CAGE CLAMP
®
. Subsequently the conductor can be inserted into the opening. After removing the operating tool, the conductor is safely clamped.
More than one conductor per connection is not permissible. If several conduc­tors have to be made at one connection point, then they should be made away from the connection point using WAGO Terminal Blocks. The terminal blocks may be jumpered together and a single wire brought back to the I/O module connection point.
Attention If it is unavoidable to jointly connect 2 conductors, then a ferrule must be used to join the wires together. Ferrule: Length 8 mm Nominal cross section

2.7.1 Isolation
Within the fieldbus node, there are three electrically isolated potentials.
• Operational voltage for the fieldbus interface.
• Electronics of the ECO coupler and the bus modules (internal bus).
• All bus modules have an electrical isolation between the electronics (inter-
nal bus, logic) and the field electronics. Some analog input modules have each channel electrically isolated, please see catalog.

Attention The ground wire connection must be present in each group. In order that all protective conductor functions are maintained under all circumstances, it is recommended that a ground wire be connected at the beginning and end of a potential group. (ring format, please see chapter "2.8.3"). Thus, if a bus mod­ule comes loose from a composite during servicing, then the protective con­ductor connection is still guaranteed for all connected field devices.
When using a joint power supply unit for the 24 V system supply and the 24 V field supply, the electrical isolation between the internal bus and the field level is eliminated for the potential group.

2.7.2 System Supply
2.7.2.1 Connection
The WAGO-I/O-SYSTEM 750 requires a 24 V direct current system supply (-15% or +20 %). The power supply is provided via the ECO coupler and, if necessary, in addition via the internal system supply modules (750-613). The voltage supply is reverse voltage protected.
Attention
The use of an incorrect supply voltage or frequency can cause severe damage to the component.
Fig. 2-11: System Supply g0xxx16e
The direct current supplies all internal system components, e.g. ECO coupler electronics, fieldbus interface and bus modules via the internal bus (5 V sys­tem voltage). The 5 V system voltage is electrically connected to the 24 V sys­tem supply.

Attention Resetting the system by switching on and off the system supply, must take place simultaneously for all supply modules (ECO coupler and 750-613).
2.7.2.2 Alignment
Recommendation A stable network supply cannot be taken for granted always and everywhere. Therefore, regulated power supply units should be used in order to guarantee the quality of the supply voltage.
The supply capacity of the ECO coupler or the internal system supply module (750-613) can be taken from the technical data of the components.
Internal current consumption*)
Residual current for bus termi­nals*)
*) cf. catalogue W4 Volume 3, manuals or Internet Example ECO Coupler:
Current consumption via system voltage: 5 V for electronics of the bus modules and ECO coupler
Available current for the bus modules. Provided by the bus power supply unit. See ECO coupler and internal system supply module (750-613)
internal current consumption:350 mA at 5V residual current for bus modules : 650 mA at 5V sum I
: 1000 mA at 5V
(5V) total
The internal current consumption is indicated in the technical data for each bus terminal. In order to determine the overall requirement, add together the val­ues of all bus modules in the node.
Attention If the sum of the internal current consumption exceeds the residual current for bus modules, then an internal system supply module (750-613) must be placed before the module where the permissible residual current was ex­ceeded.
Example:
WAGO-I/O-SYSTEM 750 DeviceNet
A node with a PROFIBUS ECO Coupler consists of 10 relay modules (750-517) and 20 digital input modules (750-405).
Current consumption: 10* 90 mA = 900 mA 20* 2 mA = 40 mA Sum 940 mA
The ECO coupler can provide 650 mA for the bus modules. Conse­quently, an internal system supp ly module (750-613), e.g. in the mid­dle of the node, should be added.

Recommendation With the WAGO ProServe® Software smartDESIGNER, the assembly of a fieldbus node can be configured. The configuration can be tested via the inte­grated accuracy check.
The maximum input current of the 24 V system supply is 260 mA. The exact electrical consumption (I

Note If the electrical consumption of the power supply point for the 24 V-system supply of the ECO coupler exceeds 260 mA or 500 mA for the 750-613, then the cause may be an improperly aligned node or a defect.
During the test, all outputs, in particular those of the relay modules, must be active.

2.7.3 Field Supply
2.7.3.1 Connection
Sensors and actuators can be directly connected to the relevant channel of the bus module in 1-/4 conductor connection technology. The bus module supplies power to the sensors and actuators. The input and output drivers of some bus modules require the field side supply voltage.
The power supply modules provide field side power (DC 24V). In this case it is a passive power supply without protection equipment. Power supply mod­ules are available for different potentials, e.g. DC 24 V, AC 230 V or others. Likewise, with the aid of the power supply modules, various potentials can be set up. The connections are linked in pairs with a power contact.
Fig. 2-13: Field Supply (Sensor / Actuator) g0xxx17e
Note The 24 V field supply can be connected also directly to a bus module, if the connection points are not needed for the peripheral device supply. In this case, the connection points need the connection to the power jumper contacts
.
The supply voltage for the field side is automatically passed to the next mod­ule via the power jumper contacts when assembling the bus modules .
The current load of the power contacts must not exceed 10 A on a continual basis. The current load capacity between two connection terminals is identical to the load capacity of the connection wires.
