Figure 2-9 Installation of an extension module
Open the fixing clamp of the extension module, push the exten-
sion module into the guide sleeve and carefully push the mod-
ule down until you reach the basic module (Figure 2-8h and i).
Connect both modules with one connection clamp (see photo to
the left) and tighten the nut (wrench size 13) such that there is
no gap any more between both modules. Tighten by approx. 2
turns, but do not use any force.
Now tighten the fixing clamp of the extension module.
If further extension modules are to be used, install them in the
same way.
Installing the end cap Before you install the last extension module, you have to install the
end cap on this module.
Take off the plastic protective cap at the end of the extension
module.
Place the block and then the spring of the end cap onto the
extension module (Figure 2-10a).
