DIN rail 
Removal 
1.  Take off the terminal blocks without disconnecting the 
wires (Fig. 10) 
2.  Insert a screwdriver into the eyelet of the slide interlock 
(Fig. 11) 
3.  Loosen the slide interlock pushing the screwdriver in the 
direction of the arrow 1, and then remove the relay from the DIN 
rail pulling the device in the direction of the arrow 2.
