DANGER
!
Rotating shafts and electrical equipment can
be hazardous. Therefore, it is strongly
recommended that all electrical work
conform to National Electrical Code (NEC)
and all local regulations. Installation, start-
up and maintenance should be performed
only by qualified personnel.
Motor control equipment and electronic controls are connected to
hazardous line voltages. When servicing drives and electronic
controls, there will be exposed components at or above line
potential. Extreme care should be taken to protect against shock.
Stand on an insulating pad and make it a habit to use only one
hand when checking components. lways work with another
person in case of an emergency. Disconnect power whenever
possible to check controls or to perform maintenance. Be sure
equipment is properly grounded. Wear safety glasses whenever
working on electric control or rotating equipment.

WARNING
!
Warnings Against Unintended Start
1. While the drive is connected to the C line, the motor can be
brought to a stop by means of external switch closures, serial
bus commands or references. If personal safety
considerations make it necessary to ensure that no
unintended start occurs, these stops are not sufficient.
2. During programming of parameters, the motor may start. Be
certain that no one is in the area of the motor or driven
equipment when changing parameters.
3. motor that has been stopped may start unexpectedly if
faults occur in the electronics of the drive, or if an overload, a
fault in the supply C line or a fault in the motor connection or
other fault clears.
4. If the Local/Hand key is activated, the motor can only be
brought to a stop by means of the Stop/Off key or an
external safety interlock.
CAUTION
!
Electronic components of BACnet portal are
sensitive to electrostatic discharge (ESD).
ESD can reduce performance or destroy
sensitive electronic components. Follow
proper ESD procedures during installation
or servicing to prevent damage.
Touching electrical parts may be fatal, even after equipment has
been disconnected from AC line. To be sure that capacitors have
fully discharged, wait 14 minutes for 208 V and 460 V units and
30†minutes for 600 V units over 25 HP after power has been
removed before touching any internal component.

Introduction
The BACnet portal is a microprocessor based communication
server that provides seamless translation between BACnet and
Trane TR1 Series variable frequency drives. For TR1 Series
FD applications into Tracer Summit, BACnet/Ethernet and
BACnet/IP are the supported connection types. The BACnet
portal provides a dedicated Ethernet port and two serial
communication ports which can be configured for two different
protocols. Baud rates are software selectable and default to 9600
baud rate. Up to ten drives can be connected to a single BACnet
portal.
The BACnet portal serves as a gateway to the Johnson Controls
Metasys® N2 protocol resident in the TR1 Series FD. The
BACnet port operates with an internal BACnet server operating
protocol through standard CAT 5 Ethernet cabling. The serial port
(port 2) connection uses EIA-485, half duplex, 9600 baud,
shielded twisted-pair wiring. Data points from the N2 protocol are
mapped to Analog alue (A ) and Binary alue (B ) BACnet
objects.
Appendix A at the back of this manual contains the drive point
maps for BACnet.
About this manual
The information in this manual is intended to provide
comprehensive information on installation and set up of the TR1
Series FD for communication over a BACnet network.
It is assumed that the user has knowledge of the capabilities of the
BACnet network in addition to an understanding of the TR1 Series
FD. For specific information on operation of the drive, refer to the
TR1 Series VFD Installation and Operation Manual, document
number TR1-S X10A-EN.
Ordering information

Power switch. Two position on/off power switch.
Portal address label. Identifies factory-set or default portal
addresses used in BACnet.
Port connectors label. Identifies factory-settings for
communication ports 1 and 2. Default setting for port 1 is no
connection. Default setting for port 2 is EIA-485 2-wire to drive.
24 VAC connector. Input power for BACnet module.
Format button. Not used.
Address rotary switches. Rotary switches used to set BACnet
portal network addresses. Set addresses 01-99 with DIP switch 5
in the +0 position. Set addresses 100-199 with DIP switch 5 in the
+100 position.
Port 1. Preferred port for ARCnet connection. Selectable for
ARCnet or 2-wire EIA-485. Set DIP switch 4 (Port 1) to Other to
enable linking drives with EIA-485 wiring. Set DIP switch 4 (Port
1) to ARC156 for use as ARCnet connector. (See DIP switches.)
This port is not used for Tracer Summit connection.

LED indicators. Status indicator lights for functions as labeled.
Access port. Utility port for factory programming, set up, and to
assign the IP address. The access port cannot be used as a
communication point or to download memory to the BACnet.
D P switches. Two position switches used to enable selection of
IP address, module address, and network type. Sw1 and Sw2
are disabled in TR1 Series FD communication applications.
Keypad/Display port. Access port for optional keypad.
Port 2. Preferred port for EIA-485 connection to the drives. The
terminal is jumper selectable for 2-wire/4-wire EIA-485 or EIA-
232. Default setting is EIA-485 (2-wire).
Port 2 configuration jumpers. Jumper placement determines
the configuration for EIA-485 (2-wire), EIA-485 (4-wire), or
EIA-232 communication for Port 2. Default is EIA-485 2-wire.
Ethernet port. Ethernet network connector supports 10baseT
network communication with BACnet.
