Direct exposure to sunlight may have an adverse effect on the temperature range. NOTE If the product is exposed to lower or higher ambient temperatures, continuous operation cannot be guaranteed. If temperatures exceed the maximum values, the charging station will automatically decrease the charging current to decrease the internal temperature of the charging station. This stabilises the internal temperature and makes it less likely that a transaction will be unexpectedly paused. NOTE If the product is directly exposed to sunlight, the automated temperature management may automatically start below the maximum ambient temperature. Therefore, wherever possible, avoid exposing the charging station to direct sunlight. NOTE Where products are exposed to the elements of nature, the enclosure can be subject to gradual aging of the material, which can result in product discolouration over time. Therefore, wherever possible, place the product in a sheltered place to optimise the life of the materials. EV Ultra Dual Installation manual English 11 4. Preparing the installation First step is to prepare the physical installation of the EV Ultra as described in this chapter. 4.1.

Prepare the foundation of the EV Ultra Assemble the EV Ultra anchor The Smappee EV Ultra is designed to be installed at ground level using the supplied anchor. It is mandatory to use this anchor. NOTE Only top and bottom of the anchor are specified. There is no specified front or back on the EV Ultra anchor. To guarantee compact transportation, the anchor is supplied in a kit and needs assembling. Follow these instructions to assemble the different parts. 1. Disassemble the anchor kit and separate each part. Image 4: Parts of the EV Ultra anchor kit 2. Assemble the plates to the anchor. Image 5: View on the anchor assembly EV Ultra Dual Installation manual English 14 ID Description 1 Small side plate 2 Wide side plate 3 Bottom plates 4 Fasteners More information The left and right plate are the same and have slotted holes. The front and rear plate are the same and have hooks to slide in the slotted holes. These four plates have a bolted connection to the side plates. Tighten the bolted connection manually during this assembly step. 3. Put the dummy plate on top of the anchor. The six studs at the bottom of the dummy plate each fit into a hole in the anchor. Image 6: View on the dummy plate 4. Tighten the nuts for the dummy plate and the four bottom plates. Image 7: View on the fasteners EV Ultra Dual Installation manual English 15 5. If necessary, remove the round cut-outs. This can be useful for better fixation of the anchor and for connections to other EV chargers. Image 8: View on the cut-outs As a result, the anchor is ready for installation. EV Ultra Dual Installation manual English 16 Install the EV Ultra anchor NOTE To keep the dimensions of the EV Ultra during the installation of the anchor, there is a dummy plate attached to the top of the anchor. The anchor itself is symmetrical, or in other words, you can select which longest side will be the front.. NOTE Think about accessibility and usage of the charger for the driver: For example, placed lengthwise in the middle of 2 parking spots. Make sure that there is sufficient space around the charging station for service and maintenance operations as specified in the IEC 60204-1 standard. This also let adequate airflow for normal operation of the charging station. NOTE When dimensioning the foundation, it is advisable to carry out a static load capacity analysis according to the relevant standards. A stable and level ground needs to be prepared in advance. We advise a levelled concrete foundation at ground level minus the height of the anchor (705 mm). To correctly install the EV Ultra anchor: 1. Make a foundation hole large enough to accommodate the anchor. 2. Flatten the bottom of the foundation hole by creating a foundation layer made of a dry mixture of sand and cement. The minimum dimensions of this foundation layer are 450 mm by 750 mm. This is a bit larger than the dimensions of the anchor, to make sure a stable foundation is created. 3. Reinforce the corners of the foundation layer by placing concrete blocks on the foundation layer at the points where the corners of the anchor will be. Make sure the concrete blocks are level in both directions. If not, adjust until level. 4. Place the EV Ultra anchor on the concrete blocks. If needed, the anchor can be fixed to the concrete blocks by screwing a bolt in each corner of the anchor (hole diameter 16 mm). Image 9: View on the anchor fixation EV Ultra Dual Installation manual English 17 5. Route all necessary cables through the anchor. The final location of all cables may already be taken into account here (see picture below).
