1.
Earth the supply unit and each DC axis controller BG7 and BG6a separately!
Connect the PE connection X11/PE on the supply unit to the PE rail (main earth) in
the switch cabinet.
Select the protective earth conductor cross-section according to chap.4.5.
2.
Earth all other DC axis controllers BG5 to BG1 via a common protective earth
conductor! Connect in series all other PE connections X11/PE on the butt-mounted
DC axis controllers.
