Maximum cross-sections of the connection cables	120 mm²				240 mm²

cable boxes can be made in three types: free-standing, wall-mounted and built-in,
with regard to the built-in cable box, dimensions of the niche should be enlarged by 10 mm in relation to the box dimensions (similarly as in the picture of ZK-1 box),
it is possible to manufacture boxes with different dimensions adjusted to the localization needs.
