1.4 Safety Notes
Warning
Switch-off the system prior to working on bus modules!
In the event of deformed contacts, the module in question is to be replaced, as
its functionality can no longer be ensured on a long-term basis.
The components are not resistant against materials having seeping and insu-
lating properties. Members of this group include: aerosols, silicones, triglyc-
erides (found in some hand creams).
If it cannot determined that these materials appear in the component envi-
ronment, then additional measures must be taken:
- install of the components in an appropriate enclosure
- handle components only with clean tools and materials.
Attention
Soiled contacts may only be cleaned with ethyl alcohol and leather cloths.
This helps ensure compliance with ESD information.
Do not use any contact spray. The spray may impair the functioning of the
contact area.
The WAGO-I/O-SYSTEM 750 and its components are an open system. As
such, the system and its components must be installed in appropriate hous-
ings, cabinets, enclosures or in electrical operation rooms. Access must only
be provided via key or tool to authorized, qualified personnel.
The relevant valid and applicable standards and guidelines concerning the
installation of switch boxes are to be observed.
ESD (Electrostatic Discharge)
The modules are equipped with electronic components that may be destroyed
by electrostatic discharge. When handling the modules, ensure that the envi-
ronment (persons, workplace and packing) is well grounded. Avoid touching
conductive components; e.g., gold contacts.
