The modules are fixed using self-tapping screws. To mount modules, it is absolutely necessary to
use screws with metric thread with the same length as the original screws and locking elements
(washer and spring washer). When screwing modules to busbars and other assemblies, screws
with metric thread with the same length as the original screws and locking elements (washer and
spring washer) must also be used.
