Grounding on
the bus coupler
Dangerous voltages
A power pack without safe isolation may lead to
dangerous voltages in the event of a malfunction.
Injuries from electric shock and system damage may
be the consequences.
O Only use a power pack with safe isolation according
to EN 60747, VDE 0551 classification! This ensures
that the electric circuits comply with SELV/PELV
electric circuits in accordance with IEC 60364-4-41.
To connect the bus coupler load supply:
1. Set up the correct pin assignment (see Tab. 6 on
page 63) on the plug connections if you do not use
pre-assembled cables.
2. Connect the bus coupler operating voltages using the
plug connector (see "Spare parts and accessories" on
page 83).
3. Check the operating voltage specifications using the
electrical characteristics and comply with them (see
chapter "Technical data" on page 82).
4. Provide power according to Tab. 7, page 63. Select
the cable cross-section according to the cable length
and occurring currents.

6.3.5 FE connection

To discharge EMC interferences, connect the FE
O
connection (1) on the bus coupler via a low-
impedance line (with low resistance) with the
functional earth (FE).
Recommended cable cross section: 10 mm
