1. In the left-hand bottom corner of the PV array, determine reference point EL (1), see Chapter
„Preparing the Roof“.
Notice
Do NOT fully screw in the screws that subsequently must be placed: tension lines or tape measures must
be tied to them!

2. Mount the other rows of battens at intervals of x × R_Ver (measured from the bottom row of battens) respectively and
mount them with two mounting screws each to each rafter/each counter batten.
3. Mount the wedge plank at a distance of ca. 10 mm from the bottom edge of the bottom row of battens, observing Chapter
„Rules for Mounting Battens“
