2.1.1 Subject to Changes

WAGO Kontakttechnik GmbH & Co. KG reserves the right to provide for any

alterations or modifications. 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.

Appropriate housing (per 2014/34/EU) is required when operating the WAGO-

I/O-SYSTEM 750 in hazardous environments. Please note that a prototype test

2.1.4 Technical Condition of Specified Devices

The devices to be supplied ex works are equipped with hardware and software

configurations, which meet the individual application requirements. WAGO

Kontakttechnik GmbH & Co. KG will be exempted from any liability in case of

changes in hardware or software as well as to non-compliant usage of devices.

Please send your request for modified and new hardware or software

configurations directly to WAGO Kontakttechnik GmbH & Co. KG.

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.

The I/O module has 2 input channels, providing a direct, intrinsically safe

connection to 2-wire sensors. The input signals are connected to the DI 1 or DI 2

CAGE CLAMP

terminals and the sensor supplies to the Uv 1 or Uv 2 CAGE

CLAMP

terminals.

The Uv terminals supply a short-circuit proof voltage of 8.2 V to the sensors.

Use shielded signal lines!

Only use shielded signal lines for analog signals and I/O modules which are

equipped with shield clamps. Only then can you ensure that the accuracy and

interference immunity specified for the respective I/O module can be achieved

even in the presence of interference acting on the signal cable.
