According to the alignment of the power cable, the location of the installation pipe is determined. The pipe is placed into the foundation and used to connect the charging station to the network. It is recommended that the installation pipe ends over the foundation and not beneath the foundation. The bending radius of the power cables must be considered when placing the installation pipe. The dimension of the pipe depends on the number and diameter of power cables which will be inserted. In the case of clustering of charging stations in the same area, it must be considered that two power cables will be inserted into the installation pipe. The size of the opening at the top of foundation enables the installation of two installation pipes that are used when the clustering of charging stations is executed.

Important: Make sure that the anchoring structure is completely inserted, tha is in horizontal position and that the part with holes is oriented towards the sky.

The concrete base is placed into the construction pit to the level that enables the top of the underground anchoring element to reach the desired final height. The final height in this case is the level of surface finish after completed works (for example the top level of paving stones, tiles, or curb). The concrete base is levelled so that the anchoring element can be vertically aligned. It is of utmost importance that the anchoring element is aligned very precisely. Lean concrete mix should be used for the concrete base (with less cement than water).

Important: When inserting the anchoring structure be sure that the orientation is appropriate depending on how you want your charging station turned.

  1. The installation pipe is inserted through the opening of the underground foundation anchor and attached with a wire to prevent it from slipping into the foundation during concrete works. The installation pipe, which has been cut to its final length, must be clogged on both ends with paper or similar material, so that the concrete cannot enter the pipe.

  2. The concrete works can be started at this point. First the area around the installation pipe is concreted, where the pipe must remain accessible after the concrete works are finished.

  3. Once the concrete reaches the level of the frame, the concrete works continue through the upper opening of the underground anchoring element, where the installation pipe is placed. The entire space inside the frame must be filled with concrete. In the case of low temperatures, the concrete must contain anti-icing additives.

  4. The next step is precise levelling of the foundation and the concrete around the frame, where the finishing tiles will be placed. Precise levelling of the underground anchoring element is important for later installation of the charging station. After the construction of the foundation is finished, the charging station can be aligned only with the use of washers, placed on the bolts of the underground anchoring element.

  5. The concrete must be left to dry for at least 48 hours (two days) before the cables are inserted into the foundation and the charging station is installed on the foundation.

The figure above shows the upper plate of the underground anchoring structure, together with its dimensions. The installation pole for INCH charging station(s) is fixed to the bolts on the underground anchoring structure. A ring spanner is used to fix the station to the foundation. The pole has at the strategically located height weakened structure. This allows pole to break at that specific point in case a car hit it. A pole already has drilled holes where mounting bracket can be attached and secured with bolts.

Press the mounting bracket against the wall and mark the places where holes need to be drilled to insert the anchors and screws. If cables are routed through the wall, make sure that the electrical box has been installed at the right location before installing the mounting bracket. On the picture below screws location is shown with the red circles.

Important: In some cases for example when the mounting bracket is secured to the soft insulation e.g. Styrofoam special wall plugs are needed.

...

Remove the maintenance doors on the side either using hex key or regular key if the enclosure came with the keyhole.

Important: Key to unlock the key-lock comes with the charging station.

In the bigger gland you should make sure that the rubber inside is of correct size. For cable’s dimensions of up to 5x6 mm2 use the tighter rubber which should be already inside the gland by default. For the cables with the 5x10 mm2 use looser rubber.

Important: Diameter of gland rubbers are 1.5 cm for the tighter of the rubbers and 2.1 cm for the looser one.

...

  1. The rubber can be changed after the removal of the gland plastic top (it need to be unscrewed) and by simply pushing the rubber out of the gland. After the new rubber is inserted into the gland screw the plastic gland top back on.

  2. Proceed with the preparation of cables. First the cable jacket of power supply cables needs to be removed. Around 15 cm should be removed so that the wires lengths are sufficient to connect them to the elements inside the charging station.

  3. Pull the power supply cable through the gland. About 15 cm of power supply cable should be pulled to the other side of the gland. About 2 cm of cable jackets should be put through the cable gland as well. This will make cable manipulations inside the charging station easier.

Important: Inserting cables through the gland is easier by loosening the gland screw cap by turning it counter- clockwise.

Important: Make sure that cables are inserted in correct cable glands.

...

Insert the UTP cable through the gland. About 20 cm of UTP cable should be put out of the gland.

Important: UTP cabel used should be UTP Category 6, 4x2 AWG LSOH.

...

After the cable is through the gland put the UTP plug on the UTP cable without cable jacket.

...

Important: Make sure that each wire is in its own slot of the connector.
