Safety Note
WARNING
Failure to follow instructions below could result in death or serious injury.
Safety Regulations
1. The frequency converter must be disconnected from mains if repair work is to be carried out. Check that the mains
supply has been disconnected and that the necessary time has passed before removing motor and mains plugs.
2. The [STOP/RESET] key on the keypad of the frequency converter does not disconnect the equipment from mains and is
thus not to be used as a safety switch.
3. Correct protective earthing of the equipment must be established, the user must be protected against supply voltage, and
the motor must be protected against overload in accordance with applicable national and local regulations.
4. The earth leakage currents are higher than 3.5 mA.
5. Protection against motor overload is set by par. 1-90 Motor Thermal Protection. If this function is desired, set par. 1-90
Motor Thermal Protection to data value [ETR trip] (default value) or data value [ETR warning]. Note: The function is
initialized at 1.16 x rated motor current and rated motor frequency. For the North American market: The ETR
functions provide class 20 motor overload protection in accordance with NEC.
6. Do not remove the plugs for the motor and mains supply while the frequency converter is connected to mains. Check
that the mains supply has been disconnected and that the necessary time has passed before removing motor and mains
plugs.
7. Please note that the frequency converter has more voltage inputs than L1, L2 and L3, when load sharing (linking of DC
intermediate circuit) and external 24 Vdc have been installed. Check that all voltage inputs have been disconnected
and that the necessary time has passed before commencing repair work. WARNING
Warning against Unintended Start
1. The motor can be brought to a stop by means of digital commands, bus commands, references or a local stop, while the
frequency converter is connected to mains. If personal safety considerations make it necessary to ensure that no
unintended start occurs, these stop functions are not sufficient.
2. While parameters are being changed, the motor may start. Consequently, the stop key [STOP/RESET] must always be
activated; following which data can be modified.
3. A motor that has been stopped may start if faults occur in the electronics of the frequency converter, or if a temporary
overload or a fault in the supply mains or the motor connection ceases.
Consequently, disconnect all electric power, including remote disconnects before servicing. Follow proper lockout/tagout
procedures to ensure the power can not be inadvertently energized. Failure to follow recommendations could result in death
or serious injury.

How to Install
The BACnet Interface
Cabling
Cable lengths and number of nodes
The maximum cable length allowable in one segment is dependent on the transmission speed. The total cable length
includes drop cables if any. A drop cable is the connection from the main bus cable to each node.
Drop cable connection (i.e. T-connection) is not recommended, due to the increased risk of reflection occurring. Instead,
Trane recommends direct connection of the frequency converter.
Note that a repeater is a node in both of the two segments it connects. The number of frequency converters is based on a
single #.4 system. If there are two or more devices (e.g. PC tools, Routers), the number of frequency converters must be
reduced correspondingly.
-Maximum length of an .4TP segment: 1200 meters (4000 feet)
-Impedance: 100 to 130 Ohm
-Resistance: <110 Ohm/km
-Capacitance: <100 pF/m
Distributed capacitance between conductors and shield shall be less that 200 pF per meter
-Cross section: 0.82 mm
2
conductor area, corresponding to AWG 18
-Cable type: twisted in pairs, 1 x 2, or 2 x 2 wires
-Screening: Copper-braided screen or braided screen and foil screen
Use of the same cable type throughout the entire segment is recommended to avoid impedance mismatch.
1757ZA145.11
Network Connection
Connect the frequency converter to the RS-485 network as follows (see also diagram):
1. Connect signal wires to terminal 68 (P+) and terminal 69 (N-) on the main control board of the frequency converter.
2. Connect the cable screen as described under chapter Bus Cabling.
Note
Screened, twisted-pair cables are recommended in order to reduce noise between conductors.

Switches S201, S202, and S801
Switches S201 (A53) and S202 (A54) are used to select a current (0-20 mA) or a voltage (-10 to 10 V) configuration of the analog
input terminals 53 and 54 respectively.
Switch S801 (BUS TER.) can be used to enable termination on the RS-485 port (terminals 68 and 69).
See drawing Diagram showing all electrical terminals in section Electrical Installation.
Default setting:
S201 (A53) = OFF (voltage input)
S202 (A54) = OFF (voltage input)
S801 (Bus termination) = OFF
Note
When changing the function of S201, S202 or S801 be careful not to use force for the switch over. It is recommended to
remove the keypad fixture (cradle) when operating the switches. The switches must not be operated with power on the
frequency converter.

Cable Routing
The BACnet communication cable must be kept away from motor and brake resistor cables to avoid coupling of high
frequency noise from one cable to the other. Normally a distance of 200 mm (7.9 in.) is sufficient, but maintaining the
greatest possible distance between cables is generally recommended, especially where cables run in parallel over long
distances.
When crossing is unavoidable, the BACnet cable must cross motor and brake resistor cables at an angle of 90 degrees.

TR200 Embedded BACnet Operating Instructions 11

Bus Cabling
EMC Precautions
The following EMC precautions are recommended to achieve interference-free operation of the BACnet network. Additional
EMC information is available in the TR200 Design Guide, MG.12.IX.YY . Please also consult the BACnet MS/TP manual for further
installation guidelines.
Note
Ensure compliance with relevant national and local regulations, for example in protective earth connection.
Single Ground Shielding
For installing the bus cable on TP, two different strategies can be followed, Single ground of shield and multiple ground of
shield. Each strategy has both advantages and disadvantages. The following chapter explains the different between the two
strategies. The single ground shield is specified in the ANSI/ASRAHE 135-2004 standard. The solution benefits by having only
one ground connection of the shield, by doing so the possibility for ground loop of equalizing current is heavily reduced. In
these systems the shield of the TP cables has to be isolated from ground at all stations, except one. At each station the shield
from the two cables has to be connected with each other, and isolated from ground. The best solution for this has been
proven to be the use of shrink tubes. The single ground shielding is a good approach where the system uses long bus cables.
If two buildings have to be connected over the same P bus cable, the use of fiber optic has to be considered. This will prevent
that a lightning stroke will be carried from one building to another, and problem with difference in earth potential can be
neglected.
Multiple Ground Shielding
If the distance between the individual drives is limited (e.g. inside a cabinet or in one control room) Trane recommends
connecting the screen to ground at both ends of the bus cable. This ensures the maximum protection from EMC noise.
Connecting the screen at each end will require that each BACnet device has the same earth potential or an equalizing current
will flow in the screen of the cable and cause disturbance and poor performance of the system. Low impedance to ground
connection of the screen can be achieved by connecting the surface of the screen to ground, by means of a cable clamp or a
conductive cable gland. The TR200 Series supplies various clamps and brackets to enable a proper ground connection of the
BACnet cable screen.
Trane recommends to connect the screen to ground at both ends of the bus cable. This ensures the maximum protection
from EMC noise. Connecting the screen at each end will require that each BACnet device has the same earth potential or else
an equalizing current will flow in the screen of the cable and cause disturbance and poor performance of the system. Where
this is not possible, the screen can be isolated from the chassis of the drive by use of shrink-tubing. It must be pointed out
that the routing of the BACnet cable must be established with a maximum distance to other cables such as mains, motor
cable, etc.
