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 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 750-479/000-001 I/O module operates with all couplers / controllers in sync
with the internal data bus. In connecting to the PROFIBUS 750-303 fieldbus
coupler, the measured values can also be recorded synchronously (fieldbus)
network-wide. The required triggering is then carried out via this special
PROFIBUS DP/FMS coupler (12 Mbaud). If it receives the “Global Control
Command”, it initiates measured value acquisition. For the measured value
scaling, a delay of one cycle can be expected. Sampling cycles of ≥1 ms can be
achieved.
