2.1.1 Subject to Changes

WAGO Kontakttechnik GmbH & Co. KG reserves the right to provide for any
alterations or modifications that serve to increase the efficiency of technical
progress. WAGO Kontakttechnik GmbH & Co. KG owns all rights arising from
the granting of patents or from the legal protection of utility patents. Third-party
products are always mentioned without any reference to patent rights. Thus, the
existence of such rights cannot be excluded.

2.1.2 Personnel Qualifications

All sequences implemented on WAGO-I/O-SYSTEM 750 devices may only be
carried out by electrical specialists with sufficient knowledge in automation. The
specialists must be familiar with the current norms and guidelines for the devices
and automated environments.

All changes to the coupler or controller should always be carried out by qualified
personnel with sufficient skills in PLC programming.

2.1.3 Use of the WAGO-I/O-SYSTEM 750 in Compliance with
Underlying Provisions

Fieldbus couplers, fieldbus controllers and I/O modules found in the modular
WAGO-I/O-SYSTEM 750 receive digital and analog signals from sensors and
transmit them to actuators or higher-level control systems. Using programmable
controllers, the signals can also be (pre-) processed.

The devices have been developed for use in an environment that meets the IP20
protection class criteria. Protection against finger injury and solid impurities up to

12.5 mm diameter is assured; protection against water damage is not ensured.
Unless otherwise specified, operation of the devices in wet and dusty
environments is prohibited.

Operating the WAGO-I/O-SYSTEM 750 devices in home applications without
further measures is only permitted if they meet the emission limits (emissions of
interference) according to EN 61000-6-3. You will find the relevant information
in the section “Device Description” > “Standards and Guidelines” in the manual
for the used fieldbus coupler/controller.

10 Important Notes WAGO-I/O-SYSTEM 750

4.1 Mounting Sequence

Fieldbus couplers/controllers and I/O modules of the WAGO-I/O-SYSTEM 750
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.

Pos: 22.2 /S erie 750 (WAGO-I/O-SYSTEM)/Wi c htige Erläut er u ng e n/Sicherhei ts - und sonstige Hinweise/Achtung/Achtung: Busklemmen nur in vorgesehener Reihenfolge stecken! @ 6\mod_1256194177073_21.docx @ 43429 @ @ 1

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.

4.2.1 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 3: Insert I/O modu le (sample)

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

carrier rail.

Figure 4: Snap the I/O module into place (sample)

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.

enclosure that fulfils the requirements of the applicable standards (see the
marking) EN 60079-0, EN 60079-11, EN 60079-15 and EN 60079-31.
For use as group I electrical apparatus M2 the apparatus shall be erected in
an enclosure that ensures a sufficient protection according to EN 60079-0
and EN 60079-1 and the degree of protection IP64.
The compliance of these requirements and the correct installation into an
enclosure or a control cabinet of the devices shall be certified by an ExNB.

2. Measures have to be taken outside of the device that the rating voltage is not

3. Dip-switches, binary-switches and potentiometers, connected to the module

may only be actuated when explosive atmosphere can be excluded.

4. The connecting and disconnecting of the non-intrinsically safe circuits is

only permitted during installation, for maintenance or for repair purposes.
The temporal coincidence of explosion hazardous atmosphere and
installation, maintenance resp. repair purposes shall be excluded.
This is although and in particular valid for the interfaces “Memory-Card”,
“USB”, “Fieldbus connection”, “Configuration and programming interface”,
“antenna socket”, “D-Sub”, “DVI-port” and the “Ethernet interface”. These
interfaces are not energy limited or intrinsically safe circuits. An operating
