•
Keep the ground wire connections as short as
possible.
•
•
≥200 mm (7.9 in)
Ensure that all stations connected to the fieldbus
network are connected to the same ground
potential. When there are long distances between
the stations in a fieldbus network, connect the
individual station to the same ground potential.
Install equalizing cables between the system
components.
Electrical contact between the cable screen and
the frequency converter enclosure or ground is
not allowed in Ethernet installations. The RJ45
connector of the Ethernet interface provides an
electrical path for the burst transient to ground.

The BACnet/IP MCA 125 option features a built-in Ethernet
switch with 2 Ethernet RJ45 connectors. Where the
enclosure protection rating if higher than IP2x, the
frequency converter may be equipped with two M12
connectors instead.
The module enables the connection of several BACnet/IP
options in a line topology as an alternative to a traditional
star topology.
The 2 ports are equal. If only 1 connector is used, either
port can be used.

NOTICE
In line topology, activate the built-in switch by powering
all frequency converters, either by mains or a 24 V DC
option card.
NOTICE
Installing frequency converters of different power sizes in
line topology may result in unwanted power-off behavior
when using control word timeout (parameter 8-02 Control
Word Source to parameter 8-06 Reset Control Word
Timeout). Mount the frequency converters with the
longest discharge time first in the line topology. In
normal operation, the frequency converters with bigger
power sizes have a longer discharge time.
Illustration 3.2 Star Topology
3.5.1.2 Line Topology
In many installations, line topology enables simpler cabling
and the use of smaller or fewer Ethernet switches. The
BACnet/IP interface supports line topology with its 2 ports
and built-in Ethernet switch.
When line topology is used, take precautions to avoid
timeout in the BMS when more than 8 frequency
converters are installed in series. Each frequency converter
in the network adds a small delay to the communication
due to the built-in Ethernet switch. When the update time
is too short, the delay can lead to a timeout in the BMS.

3.6 Mounting
1.
Check whether the fieldbus option is already
mounted in the frequency converter. If the option
is already mounted, go to step 6.
2.
Remove the LCP or blind cover from the
frequency converter.
3.
Use a screwdriver to remove the front cover and
the LCP cradle.
4.
Mount the fieldbus option with the Ethernet port
facing upwards for top cable entry (see
Illustration 3.7), or with the Ethernet port facing
downwards for bottom cable entry (see
Illustration 3.8).
5.
Remove the knockout plate from the new LCP
cradle.
6.
Mount the new LCP cradle.
NOTICE
For ring/redundant topology, ensure that the redundancy
manager switch supports the detection of loss of line
topology. The switch inside the BACnet/IP interface does
not support this detection, as the redundancy manager
has to perform this task.
VLT
AutomationDrive
Illustration 3.5 Recommended Design Rules
Configure the redundancy manager switch to
clearly define the ports that connect to the ring.
When the ring is closed, the main redundancy manager
tests the ring for detects. If the redundancy manager
detects a fault in the ring, it reconfigures the ring into 2
lines instead. The transition time from ring topology into 2
lines can vary from 200 ms up to several seconds
depending on the components installed in the ring. Set
the timing of the BMS controller to ensure that the
transition time does not lead to a timeout fault.
