Section 2.2.5 Grounding
3BSE 002 415R701 Rev A 2-23
Each unit takes up to four communication cables and it also provides the mechanical anchoring
of the cable. Two units can be mounted side by side or, if necessary, on top of each other.
Certain spacers are used then. This imply a maximum of 4 units on a mounting bar (16 buses).
A split ferrite core should be used on each communication cable. They should be mounted at the
cabinet entry, see Figure 2-11, and have a series impedance of at least 100 ohms in the frequency
range 50-300 MHz. The application of method with respect to communication type is given in
Table 2-1.
