Deployment and installation
Regarding the installation process, the next steps explain how to correctly install the device under the ground:
Step 1 : Drill the hole.
Use a hole saw or other dedicated tool to drill a hole into the pavement bigger enough for the enclosure (minimum
diameter 202 mm). Try to perforate it deep enough to insert the Smart Parking node completely without rising over
the surface, be sure that the enclosure remains under the pavement line approximately 10 mm.

Step 2 : Place the node into the pavement hole.
Below the device, a layer of cement must be spread to elevate the device to the correct horizontal position
independently of the depth of the hole. The diameter of the hole must be at least 202 mm.

Step 3 : Fill the hole.
Finally, the node needs to be fi xed to the pavement using Epoxy resin (commonly used for fi lling road fi ssures).
This resin should fi ll all the space between enclosure and pavement. Also, it should completely cover the top of the
enclosure ensuring protection against water, bad environmental conditions and vandalism. The Epoxy resin tested
by Libelium provides a curing time around 6-12 hours at 20 ºC and RH 50%. So the parking installation must not be
used prior this curing time.
