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

2.1.2 Personnel Qualifications

All sequences implemented on Series 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 750 Series in Complianc e wit h Unde rlying Provisions

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

The components 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 components in wet and
dusty environments is prohibited.

Operating 750 Series components 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
on "WAGO-I/O-SYSTEM 750"  "System Description"  "Technical Data" in
the manual for the used fieldbus coupler/controller.

Protect the components against materials having seeping and insulating
properties!

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.

Avoid electrostatic discharge!

The devices are equipped with electronic components that you may destroy by
electrostatic discharge when you touch. Pay attention while handling the devices
to good grounding of the environment (persons, job and packing).

The I/O module inputs provide high-side switching. If the 24V potential for field
power is switched to an input connection, the signal status for the corresponding
input channel is set to "high."

The I/O module receives the 24 V voltage supply for the field level from an
upstream I/O module or from the fieldbus coupler/controller via the power
contacts used as blade contacts. It then provides this potential to subsequent I/O
modules via the power contacts used as spring contacts.

Do not exceed maximum current via power contacts!

The maximum current to flow through the power contacts is 10 A.
Greater currents can damage the power contacts.
When configuring the system, ensure that this current is not exceeded. If
exceeded, an additional potential feed module must be used.

Use potential feed module for Ground (earth)!

The I/O module has no power contacts for PE intake and transfer. Use a potential
feed module when a PE feed is needed for the subsequent I/O modules.

With consideration of the power jumper contacts, the individual modules can be
arranged in any combination when configuring the fieldbus node. An arrangement
in groups within the group of potentials is not necessary.
