(1).Insert a screwdriver (its edge length≤6mm)into the downside
metal lock of the SPD;
(2).Push the screwdriver upwards to open the metal clip;
(3).Take the SPD out of the guide rail.
This SPD is designed for mounting on 35mm DIN guide rail.
Installation according with the following steps:
(1).Make the upside of the SPD locked into the guide rail;
(2).Push the downside of the SPD in the rail.
