Product Overview
1.3
Use the BACnet MS/TP UBR-01 router to enable communication in a BACnet network. The router is the device
sending messages through the network. The messages can
be from master to slave or slave to master, and the router
can trigger alarms and/or warnings if the communication is
lost.

2.2 Cabling of the Networks
2.2.1 BACnet MS/TP Cabling (NW #2)
22
To ensure correct functionality of the BACnet MS/TP
network, be sure to do the cabling correctly. Pay special
attention to mounting of the cable shield and to
termination of the network.
2.2.2 Ethernet Cabling (NW #1)
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.
NOTICE
Never connect the shield to terminal 61 on the
frequency converter.
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°.
Illustration 2.2 Grounding Shielded Cables
Shielding of frequency converters connected to the same
ground potential
1. Use an adequate equalizing cable to eliminate
the risk of equalizing current running into the
shield of the BACnet cables.
2. Mount the shield at the terminal marked Shld on
the router.
3. On the frequency converters, connect the shield
to the ground shield brackets.
Shielding of frequency converters without the same
ground potential
If the frequency converters do not have the same ground
potential, only connect the shield to ground in 1 location.
Expect a lower EMC performance.

90° crossing
Illustration 2.3 Cable Routing
For the Ethernet, use standard shielded Cat5e patch cables.
Maximum cable length is 100 m (328 ft).
An Ethernet switch distributes the packets to the participants on the Ethernet network. For industrial installation,
only use industrial graded products as other products may
cause faults and sporadic loss of communication.

For testing the settings in the UBR-01 router and in the
frequency converters, a BMS tool is used for:
Scanning the network.
•
Find the BACnet devices.
•
Showing the device objects.

Illustration 4.1 BMS Tool Scanning the Network
By selecting the frequency converter with device instance
1001, the BMS starts the discovery of the frequency
converter objects and shows their present value. This
proves the correct function of the UBR-01 and the
frequency converters connected via BACnet.
