20 • The WAGO-I/O-SYSTEM 750 Power Supply 2.6.2 System Supply 2.6.2.1 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 coupler / controller and, if necessary, in addition via the internal system supply modules (750-613). The voltage supply is reverse voltage protected. Fig. 2-11: System Supply g0xxx02e The direct current supplies all internal system components, e.g.
The WAGO-I/O-SYSTEM 750 • 21 Power Supply 2.6.2.2 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 coupler/controller or the internal system supply module (750-613) can be taken from the technical data of the components.
22 • The WAGO-I/O-SYSTEM 750 Power Supply The maximum input current of the 24 V system supply amounts to 500 mA. The exact electrical consumption (I(24 V)) can be determined with the following formulas: Coupler/Controller I(5 V) total = Sum of all current consumptions of the connected bus modules + internal current consumption coupler / controller 750-613 I(5 V) total = Sum of all current consumptions of the connected bus modules Input current I(24 V) = 5 V / 24 V * I(5 V) total / h h = 0.
The WAGO-I/O-SYSTEM 750 • 23 Power Supply 2.6.3 Field Supply 2.6.3.1 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 coupler/controller provides field side power (DC 24V). Power supply modules are available for other potentials, e.g. AC 230 V.
24 • The WAGO-I/O-SYSTEM 750 Power Supply Attention Some bus modules have no or very few power contacts (depends on the I/O function). Due to this, the passing on of the relevant potential is disrupted. If a field supply is required for subsequent bus modules, then a power supply module must be used. Note the data sheets of the bus modules. In the case of a node setup with different potentials, e.g. the alteration from DC 24 V to AC 230V, a spacer module should be used.
The WAGO-I/O-SYSTEM 750 • 25 Power Supply Warning In the case of power supply modules with fuse holders, only fuses with a maximal dissipation of 1.6 W (IEC 127) must be used. For UL approved systems only use UL approved fuses. In order to insert or change a fuse, or to switch off the voltage in succeeding bus modules, the fuse holder may be pulled out. In order to do this, use a screwdriver for example, to reach into one of the slits (one on both sides) and pull out the holder. Fig.
26 • The WAGO-I/O-SYSTEM 750 Power Supply Alternatively, fusing can be done externally. The fuse modules of the WAGO series 281 and 282 are suitable for this purpose. Fig. 2-18: Fuse modules for automotive fuses, Series 282 pf66800x Fig. 2-19: Fuse modules with pivotable fuse carrier, Series 281 pe61100x Fig.

This is demonstrated by complying with the standards of influential classification companies such as Germanischer Lloyd and Lloyds Register. Filter modules for 24-volt supply are required for the certified operation of the system. Item No.
28 • The WAGO-I/O-SYSTEM 750 Power Supply 2.6.5 Supply example Note The system supply and the field supply should be separated in order to ensure bus operation in the event of a short-circuit on the actuator side.
The WAGO-I/O-SYSTEM 750 • 29 Power Supply 2.6.6 Power Supply Unit The WAGO-I/O-SYSTEM 750 requires a 24 V direct current system supply with a maximum deviation of -15% or +20 %. 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. A buffer (200 µF per 1 A current load) should be provided for brief voltage dips. The I/O system buffers for ca. 1 ms.
30 • The WAGO-I/O-SYSTEM 750 Grounding 2.7 Grounding 2.7.1 Grounding the DIN Rail 2.7.1.1 Framework Assembly When setting up the framework, the carrier rail must be screwed together with the electrically conducting cabinet or housing frame.

The WAGO-I/O-SYSTEM 750 • 31 Grounding 2.7.2 Function Earth The function earth increases the resistance capacity against disturbances from electro-mechanical influences. Some components in the I/O system have a carrier rail contact that dissipates electro-magnetic disturbances to the carrier rail. Fig. 2-23: Carrier rail contact g0xxx10e Attention Care must be taken to ensure the flawless electrical connection between the carrier rail contact and the carrier rail. The carrier rail must be grounded.
32 • The WAGO-I/O-SYSTEM 750 Grounding 2.7.3 Protective Earth For the field level, the ground wire is placed onto the lower connection terminals of the power supply terminals and further reached through the lower power contacts to the neighboring bus terminals. If the bus terminal has the lower power contact, then the ground wire connection of the field devices can be directly connected to the lower connection terminals of the bus terminals.
The WAGO-I/O-SYSTEM 750 • 33 Shielding (screening) 2.8 Shielding (screening) 2.8.1 General The shielding of the data and signal conductors reduces the electromagnetic influences thereby increasing the signal quality.
