5.4 Preparing the foundation box
The following applications are only examples, as the space required for unit installation and the accessories vary de-
pending on dimensions and therefore it is up to the installer to select the best solution.
Note: the following sketches show how to install the right-hand foundation box (CD).
- Dig a pit to place the foundation box into, set up the
required cable boxes and corrugated conduits – for the
connections coming from the branching pit – and the
drainage tube.
Note: the number of cables depends on the type of system
and the accessories installed.
- Level the foundation
box with the ground
and position the
pinion of the
foundation box in line
with the top hinge of
the gate.

- Fill the pit with concrete and sink the foundation box
into it, making sure that the corrugated and drainage
tubes pass through the proper holes.
