  • connection boxes may be made in three versions: free-standing, wall-mounted and recess-mounted,
  • in case of a recess-mounted connection box, the dimension of the recess should be increased by 10 mm compared to the connection box dimensions (as in the drawing of the ZK-1 connection box),
  • it is possible to manufacture connection boxes with different dimensions, adapted to the needs at the location.
