When connecting the switch 

outputs, the overvoltage 

category must be respected !

 

 

*

When connecting an  

 

 

inductive load, such as relay,  

 

 

to the Solid State Relay 

 

 

output, it may be necessary 

to connect a snubber circuit 

in  parallel  to  the 

load  to  protect 

the output from 

engaging 

unexpectedly.  

The snubber 

circuit  must  be 

properly adapted 

to the load in order to prevent the output 

from engaging permanently.
