15

Glue new adhesive tape strips (2.1, 3.1) to inside of mounting rail (2, 3).

When reusing the mounting rail (2, 3).

 Always glue two adhesive tape strips (2.1, 3.1) next to each other because they are narrower than the adhesive tape strips (2.1, 3.1) applied at the factory

 Cut the adhesive tape strips (2.1, 3.1) so that the protective foils protrude a bit (cross-hashed areas). This makes it possible to remove the protective foils after installing the mounting rail (2, 3).
