4 Mounting

4.1 Mounting Sequence

Fieldbus couplers/controllers and I/O modules of the WAGO-I/O-SYSTEM
750/753 are 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 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 (750-600) onto the end of the fieldbus node! You
must always use a bus end module at all fieldbus nodes with WAGO-I/O­SYSTEM 750 fieldbus couplers/controllers to guarantee proper data transfer.

4.2 Inserting and Removing Devices

Perform work on devices only if they are de-energized!

Working on energized devices can damage them. Therefore, turn off the power
supply before working on the devices.

4.2.1 Inserting the I/O Module

1. Position the I/O module so that the tongue and groove joints to the fieldbus
coupler/controller or to the previous or possibly subsequent I/O module are
engaged.

Figure 7: Insert I/O Module (Example)

2. Press the I/O module into the assembly until the I/O module snaps into the
carrier rail.

Figure 8: Snap the I/O Module into Place (Example)

With the I/O module snapped in place, the electrical connections for the data
contacts and power jumper contacts (if any) to the fieldbus coupler/controller or to
the previous or possibly subsequent I/O module are established.

5.1 Connecting a Conductor to the CAGE CLAMP®

The WAGO CAGE CLAMP® connection is appropriate for solid, stranded and
finely stranded conductors.

Select conductor cross sections as required for current load!

The current consumed for field-side supply may not exceed 10 A. The wire cross
sections must be sufficient for the maximum current load for all of the I/O
modules to be supplied with power.

Only connect one conductor to each CAGE CLAMP® connection!

Only one conductor may be connected to each CAGE CLAMP® connection.
Do not connect more than one conductor at one single connection!

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.

1. To open the CAGE CLAMP® insert the actuating tool into the opening
above the connection.

2. Insert the conductor into the corresponding connection opening.

3. To close the CAGE CLAMP® simply remove the tool - the conductor is
then clamped firmly in place.

5.2.1 Supplementary Power Supply Regulations

The overvoltage protection module 750-626, which is equipped with surge
suppression for the 24 V DC field side power supply and used to filter the 24 V
DC field power supply, is required for the certified operation of the supply
module 750-613 in shipbuilding or offshore and onshore applications.

Figure 14: Power Supply Concept GL/LR

5.2.2 Power Supply Unit

The WAGO-I/O-SYSTEM 750 requires a 24 VDC voltage (system supply).

Recommendation

A stable power supply cannot always be assumed everywhere. Therefore, you
should use regulated power supplies to ensure the quality of the supply voltage.

For brief voltage dips, a buffer (200 µF per 1 A load current) must be provided.

Buffer for system power supply!

The system power supply must be buffered to bridge power outages. As the power
demand depends on the respective node configuration, buffering is not
implemented internally.
To achieve power outages of 1 ms to 10 ms according to IEC61131-2, determine
the buffering appropriate for your node configuration and structure it as an
external circuit.

Manual
Version 1.1.0

32 Connect Devices WAGO-I/O-SYSTEM 750
750-613 24V DC Power Supply (Bus)

The power demand must be determined individually depending on the entry point
of the field supply. All loads through field devices and I/O modules must be taken
into account. The field supply also impacts the I/O modules because the input and
output drivers of some I/O modules require the voltage of the field supply.

System and field supply must be isolated!

The system supply and field supply must be isolated to ensure bus operation in the
event of short circuits on the actuator side.

Power supply units are available in the eShop.

You can find suitable power supply units, e. g. from the EPSITRON series, in the
eShop on www.wago.com.
