2. Lay the loop carefully into the groove and push it down by
means of a blunt object, such as a piece of wood. The
insulation must by no means be damaged.
3. To avoid slipping of the loop, fix the loop using small wooden
wedges. Remove the wooden wedges later on.
4. Push the loop feed line through the empty conduit in place into
the barrier housing.
5. Measure the induction loop according to chapter 8.4.3.
6. We recommend to cover the inserted loop using quartz sand.
Make sure that at least 0.98 in (25 mm) remain between the
upper edge of the roadway and the quartz sand for the potting
compound.
7. Seal the groove with the potting compound.
 The temperature resistance of the loop must match the
temperature of the potting compound.
8. Allow the potting compound to cure.
