NOTICE
Shielding connection and functional earth connection!
Ä The shielding connection is done via the M12 connector housing.
Ä Ensure that the functional earth (FE) is connected correctly.
Unimpaired operation is only guaranteed when the functional earth is connected properly.
All electrical disturbances (EMC couplings) are discharged via the functional earth connec-
tion.
NOTICE
Network interruption with BPS in PROFINET linear topology!
Ä In the event of a device exchange, the PROFINET network is interrupted at this location.
Ä The PROFINET network is interrupted if the BPS is unplugged from the connection hood.
Ä If there is no voltage supply for the BPS, the PROFINET network is interrupted.
Ä Connect connection PWR/SWIN/OUT to the supply voltage or the switching inputs/outputs connec-
tion cable.
Ä PROFINET star topology: Connect the HOST/BUSIN connection to a switch with the interconnection
cable.
Ä PROFINET linear topology: Connect the HOST/BUSIN connection to the BUSOUT connection of the
upstream BPS with the interconnection cable.
Connect the BUSOUT connection to the HOST/BUSIN connection of the downstream BPS with the
interconnection cable.
