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.

Install the device 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.

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.
