Cascading CC-CO

If 2 CC-CO routes are cascaded, the bridgeable distance can be significantly increased. A requirement for this is
for the converters in the center to be supplied with auxiliary power. The auxiliary power can be fed via a 2nd
pair of pilot wires.
NOTE

i
Pay attention to the voltage drop via the pilot wires if there is a maximum power consumption of 4 W/
10 VA for each communication converter.
Both devices in the center must be configured as main-unit devices. The main-unit device for route 2 must be
operated in cascade mode.
