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 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 or controller.

Version 1.1.0
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
certificate must be obtained that confirms the correct installation of the system in
a housing or switch cabinet.
The implementation of safety functions such as EMERGENCY STOP or safety
door monitoring must only be performed by the F I/O modules within the modular
WAGO I/O SYSTEM 750. Only these safe F I/O modules ensure functional safety
in accordance with the latest international standards. WAGO's interference-free
output modules can be controlled by the safety function.

Avoid electrostatic discharge!
The devices are equipped with electronic components that may be destroyed by
electrostatic discharge when touched. Please observe the safety precautions
against electrostatic discharge per DIN EN 61340-5-1/-3. When handling the
devices, please ensure that environmental factors (personnel, work space and
packaging) are properly grounded.

Use only direct current (DC) for insulation testing!
Both the system voltage and field voltage side are capacitively coupled to the
DIN-rail. If an I/O module is mounted on the DIN-rail, application of an AC voltage
between the DIN-rail and at least one of these two potentials can lead to the
destruction of the module.
Use only direct current (DC) for insulation testing. To avoid destroying the I/O
module, you must discharge it completely before applying the test voltage again.
