DANGER
CAUTION
!
!
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, startup 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. Always 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 AC 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. A 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 AC 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.
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
About this manual
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
VFD 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 VFD. 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 Value (AV) and Binary Value (BV) BACnet
objects.
Appendix A at the back of this manual contains the drive point
maps for BACnet.
The information in this manual is intended to provide
comprehensive information on installation and set up of the TR1
Series VFD 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
VFD. For specific information on operation of the drive, refer to the
TR1 Series VFD Installation and Operation Manual, document
number TR1-SVX10A-EN.

Installation requirements
Wiring and terminal tightening specifications
Mount the BACnet enclosure as required using the predrilled
mounting holes (see Figure 2). The unit weighs approximately
15.3 pounds (7 kg).
For BACnet portals ordered without an enclosure, mount the unit
in an enclosed panel using the mounting holes provided on the
BACnet portal backplate (refer back to Figure 1). Leave about 2
inches (5 centimeters) on each side for wiring access. In addition,
the BACnet portal requires 24 VAC input power.
WARNING
!
BACnet portal is a Class 2 device (less than
30VAC, 100VA maximum). Take appropriate
isolation measures when mounting BACnet
portal in control panels where non-Class 2
devices (for example, 120VAC) or wiring are
present.
Terminal tightening and wire specifications for the TR1 Series VFD
are defined in Table I.
Total wiring length to connect up to 10 TR1 Series VFDs from the
BACnet portal should not exceed 3,000 feet (900m) at 9600 baud
rate.
