Safety Regulations 

These Safety Regulations are user hints only and may not be complete!

 

 

User-implemented Protective Measures: 

  Please cover moving parts to protect 

against injury 

through seizure

  Place a cover on the magnetic part to protect 

against injury 

through high temperatures

 

Protection circuit: 

When using DC-side switching, the coil 

must be protected by a suitable protection circuit according 
to VDE 0580, which is integrated in 

mayr

 

®

-rectifiers. To 

protect the switching contact from consumption when using 
DC-side switching, additional protective measures are 
necessary (e.g. series connection of switching contacts). The 
switching contacts used should have a minimum contact 
opening of 3 mm and should be suitable for inductive load 
switching. Please make sure on selection that the rated 
voltage and the rated operating current are sufficient. 
Depending on the application, the switching contact can also 
be protected by other protection circuits (e.g. 

mayr

 

®

-spark 

quenching unit, half-wave and bridge rectifiers), although this 
may of course then alter the switching times. 

  Take precautions 

against freeze-up of the friction 

surfaces

 in high humidity and at low temperatures.
