HARDWARE
If the user intends to install QC-PDS system and requires to main power
supplies, two different groups should be created for the same system that
do not share the DC BUS between both groups
despite being part of the
same SERCOS bus.
WARNING. Never make a parallel connection between the power DC BUS
of several groups. If several main power supplies are to be installed,
always do this in separate groups, one for each power supply, by
connecting only the units belonging to each group to the DC BUS.
