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 
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 WAGO-I/O-SYSTEM 750 and its components are an open system. It 
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.  

ESD (Electrostatic Discharge) 
The modules are equipped with electronic components that may be destroyed 
by electrostatic discharge. When handling the modules, ensure that the 
environment (persons, workplace and packing) is well grounded. Avoid 
touching conductive components, e.g. gold contacts. 

 

This manual describes the Analog Output Module 750-553 
4 AO DC 0-20 mA of the modular WAGO-I/O-SYSTEM 750. 

Handling, assembly and start-up are described in the manual of the Fieldbus 
Coupler. Therefore this documentation is valid only in the connection with the 
appropriate manual.
