Choose a ground spot with an appropriate IP value for outdoors. The higher the IP value, the better the protection. We recommend that a ground spot have an IP value of IP67 or IP68.
Make a watertight connection. The safest way to do this is by making a connection in a junction box and then filling the box with resin. The resin in the junction box ensures that both the connection and garden spot is completely sealed against water.
Install drainage for the ground spot to ensure that water does not remain on or around the spot. For example, you can lay down a raised gravel bed around the ground spot.
And, make sure the ground spot is not installed at the lowest part of the surface. This reduces the risk that rainwater flows in the direction of the ground spot and does not remain on or around your spot before the water dries up.
