3 Installation
3.1 Safety Instructions
See chapter 2 Safety for general safety instructions.
3.2 EMC-compliant Installation
To obtain an EMC-compliant installation, follow the
instructions provided in the relevant frequency converter
operating instructions and design guide. Refer to the
BACnet/IP master manual from the BMS supplier for further
installation guidelines.
3.3 Grounding
•Ensure that all stations connected to the eldbus
network are connected to the same ground
potential. When there are long distances between
the stations in a eldbus network, connect the
individual station to the same ground potential.
Install equalizing cables between the system
components.
•Establish a grounding connection with low HF
impedance, for example by mounting the
frequency converter on a conductive backplate.
•Keep the ground wire connections as short as
possible.
•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.
•To reduce burst transient, use high-strand wire.
3.4 Cable Routing
NOTICE
EMC INTERFERENCE
Use shielded cables for motor and control wiring, and
separate cables for eldbus communication, motor
wiring, and brake resistor. Failure to isolate eldbus
communication, motor, and brake resistor cables can
result in unintended behavior or reduced performance.
Minimum 200 mm (7.9 in) clearance between power,
motor, and control cables is required. For power sizes
above 315 kW (450 hp), increase the minimum distance
to 500 mm (20 in).
NOTICE
When the eldbus cable crosses a motor cable or a brake
resistor cable, ensure that the cables cross at an angle of
90°.

3.5 Topology
3.5.1 Topology Types
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.
3.5.1.1 Star Topology
130BE799.10
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.
Set the update time as shown in Table 3.1. The numbers
given are typical values and can vary from installation to
installation.

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 dierent power sizes in
line topology may result in unwanted power-o 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 rst in the line topology. In
normal operation, the frequency converters with bigger
power sizes have a longer discharge time.

3.5.1.3 Ring/Redundant Topology
130BE801.10
Illustration 3.4 Ring/Redundant Topology
Ring topology can increase the availability of an Ethernet
network.
For ring topology:
•Install a special switch (redundancy manager)
between the BMS controller and the frequency
converters.
•Congure the redundancy manager switch to
clearly dene 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 recongures 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.
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.
3.5.1.4 Recommended Design Rules
•Pay special attention to active network
components when designing an Ethernet
network.
•For line topology, a small delay is added with
each additional switch in the line. For more
information, see Table 3.1.
•Do not connect more than 32 frequency
converters in series. To prevent unstable or faulty
communication, set the timing, if this limit is
exceeded.
