In this configuration, when the Master unit reaches the set intervention threshold, it manages also the intervention
of the first Slave unit by means of the command MCMD (output terminals 5 and 6), which is cascade connected
to the input SIN of it (terminals 7 and 8). At its turne, the second Slave will be enabled by the command SOUT
(output terminals 9 and 10) of the first Slave.
In case of inverters provided with internal command for external brake units, all the 6KBU300 units must be set
as Slave. The terminals MCMD and 0V24 of the drive have to be connected to the terminals 7 and 8 (SIN) of the
first 6KBU300, which will be of course connected to the next through its own terminals 9 and 10 (SOUT), as
described in the next page.

When a very close mounting of several braking units is needed, it is necessary to keep among
them a minimum distance of 5 centimeters (2 inches).
