F-series is available in two parallel versions: F and F NBS, which are nearly identical apart from the base structure. In the F NBS system, the side panels can be installed last after the cabinet has been furnished and cabled.
The enclosure structure can consist either of one section only, or of several modules and spaces. The cell centre can be constructed L- or even U-shaped, as required or as the available space allows.
Bus bars are installed at the back of the centre. The aluminium or copper bus bars can be installed at any height.
Most frame parts have been provided with pre-punched holes, which makes protective grounding easy. Doors are grounded through the frame structure via hinges and screws.
Screen-protected structures can be built on two levels with either plastic or metal partition covers and two alternative door solutions.
