The check should be carried out for the total length of the bus. When using a TSX EF ACC 99 connection box to form a branch, it must be remembered that the Fipio standard does not authorize an electrical branch and that the length of the TSX FP CC •00 branch cable must be multiplied by 2.
The length of a section must never exceed 1000 m. If this is the case, a second section with an electrical or optical repeater must be used.
