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 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 Compliance with Underlying

Provisions

Couplers, 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 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.

Installation only in appropriate housings, cabinets or in electrical operation

rooms!

The WAGO-I/O-SYSTEM 750 and its components are an open system. As such,

install the system and its components exclusively in appropriate housings,

cabinets or in electrical operation rooms. Allow access to such equipment and

fixtures to authorized, qualified staff only by means of specific keys or tools.

Replace defective or damaged devices!

Replace defective or damaged device/module (e.g., in the event of deformed

contacts), since the long-term functionality of device/module involved can no

longer be ensured.

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

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
