1.4 Safety Notes

Attention
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
insulating properties. Belonging to this group of materials is: e.g. aerosols,
silicones, triglycerides (found in some hand creams).
If it cannot be ruled out that these materials appear in the component
environment, then additional measures are to be taken:
- installation of the components into an appropriate enclosure
- handling of the components only with clean tools and materials.
Attention
Cleaning of soiled contacts may only be done with ethyl alcohol and leather
cloths. Thereby, the ESD information is to be regarded.
Do not use any contact spray. The spray may impair the functioning of the
contact area.
The AS-Interface Slaves IP20 from the WAGO-I/O-SYSTEM 751 are open
components. They must only be assembled in housings, cabinets or in
electrical operation rooms. Access must only be given via a 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.
