2.1
Legal Bases
2.1.1
Subject to Changes
WAGO GmbH & Co. KG reserves the right to provide for any alterations or
modifications. WAGO 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 750 Series in Compliance with Underlying
Provisions
Fieldbus 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
actuators or higher-level control systems. Using controllers, the signals can also
be (pre-) processed.
The devices fulfill the requirements of protection type IP20 and are designed for
use in dry interior spaces. There is protection against finger injury and solid
impurities
≥
12.5 mm diameter is assured; protection against water damage is not
ensured.
The devices represent open-type devices. They may only be installed in
enclosures (tool-secured enclosures or operating rooms) which fulfil the listed
requirements specified in the safety instructions in chapter “Safety Advice
(Precautions)”. Use without additional protective measures in environments within
which dust, corrosive fumes, gases or ionized radiation can occur is considered
improper use.
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
