Wiring between master and slave
The master unit and the slave units are connected together
with a modular cable type VX 010. The modular cable carries
all information between the master and the slave units, i.e.
data in serial form and arc fault messages, as well as the
auxiliary supply of the slave units.
Connect the VX 010 cable to the X5 outlet (COM2) or the
connector X3-5...10 (COM1) of the master unit. Both COM ports
can be used simultaneously.
CAUTION!
If the connector X3-5...10 is used, pay special attention to the
wiring of the signals. Faulty wiring may damage the communi-
cation between the master and the slaves.
Connect the cable to COM1 or COM2 on the first slave unit.
Route the cable from the free connector of the first slave unit
(COM2 or COM1) to the COM1 (or COM2) connector of the next
slave unit, and so forth. See Figure 5.4.2-1.
