- You must be able to approach both sides of the cabinet.
- It is advisable to provide traffic routes in addition to building walls or landmarks.
- It is advisable to select a part of the plot boundary that is protected from damage.
- The installation location of the cabinet should not be a “catchment”.
- When installing the cabinet, taking into account the dimensions of the cabinet, it is necessary to dig a pit 10-10 cm larger and 60 cm deep. The assembled cabinet (with plinth) must be inserted into the pit and temporarily fixed. (The “plinth depth” is 50-60 cm!) “Installation height” (ground level) is marked on the cabinet! If the soil conditions so require, the plinth must be bolted to concrete slabs and the cabinet installed at the same time.
- After removing the door, the front cover plates of the cabinet and plinth under the door must be unscrewed by screws in order to connect and secure the cables.
- A contact to the ground must be connected to the connection terminal of the cabinet for the ground conductor connection (lower end of the PEN rail). As a technically suitable solution to this, it is most expedient to “return” the ground conductor from the grounding system of the electricity-powered building on the same route as the cable serving as the measured main line. For this purpose, a corrosion-resistant (galvanized) round steel with a cross-section of at least 100 mm2 is recommended. If the length of this return exceeds 3-4 meters, it is advisable to install an grounding probe of suitable value independently in the cabinet.
- The relevant standards and general regulations of the power suppliers apply to the laying and installation of the connecting cables. The markings on the associated cables must be clearly provided.
- After completing the cable installation work, the front covers must be replaced in reverse order, the door can be refitted by snapping on the pins.
- Then, using the excavated soil, the final, stable fixation must be achieved by ramming, layered compaction, while continuously checking the setting in both directions with a spirit level. It is recommended to use dry sand or moisture trap granules to reduce soil evaporation.
- The material of the cabinet withstands the thermal and chemical effects of asphalting, so asphalt paving in the environment is not a problem either. In this case, however, a slight slope should be created outwards from the cabinet so that precipitation does not collect at the base of the cabinet.
- The cover plates under the cabinet door can be unscrewed with screws, so that the subsequent cable connection can also be easily solved.
Addition:
The regulations of the designer and the local Electricity Supplier must be fully complied with during the installation of the cabinets.
