The lockable housings each contain a mounting plate. They are supplied with a 3-point lock and a key. After the components have been assembled, on site or in the workshop, the housing is screwed onto the mounting plate. This means that external influences on the distribution are excluded. The housing also has openings on the narrow sides of the housing for cable entry (size 130 x 50 mm) and a connection, cable 120cm, between the door and the housing for potential equalization.
