WAGO I/O System 750 Important Notes 13
753-661/000-004 4FDI 24V PROFIsafe
Observe applicable standards!
In a safety-related application, both the control as well as the attached sensors
and actuators must meet the applicable normative safety requirements. Ensure
that switches, sensors and actuators comply with current applicable standards
before use.
Power from SELV/PELV power supply only!
All field signals and field supplies connected to this I/O module (753-661/000-
004) must be powered from SELV/PELV power supply(s)!
Inadequate wire cross sections can cause temperature increases!
To avoid increasing thermal risks, only use conductor cross-sections sufficient for
the required maximum load current. The conductor cross-sections specified in
the technical data refer exclusively to the mechanical connection capacity of the
clamping points.
Ensure proper contact with the DIN-rail!
Proper electrical contact between the DIN-rail and device is necessary to
maintain the EMC characteristics and function of the device.
Replace defective or damaged devices!
Replace defective or damaged device/module (e.g., in the event of deformed
contacts).
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.
