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, 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.
CAUTION
!
Electronic components of BACLink 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 ñ even after equipment has
been disconnected from AC line. To be sure that capacitors have
fully discharged, wait 14 minutes after power has been removed
before touching any internal component.

Introduction
References
The Danfoss BACLink® is a microprocessor based communication
portal that provides seamless translation between BACnet and
Danfoss VLTs. The portal supports BACnet communications
through Ethernet, BACnet IP over Ethernet (often referred to as
Ethernet IP), ARCnet, EIA-485 (using MS/TP), or EIA-232 (PTP).
The BACLink portal provides a dedicated Ethernet port and two
serial communication ports which can be configured for different
protocols. Baud rates are software selectable. An optional EIA-485
4-wire connection is also available to extend network cable length
beyond 4000 feet.
Do not input multiple protocol formats to the portal at the same time
since this can cause a communications loop and generate
excessive electrical noise.
BACLink accesses the Johnson Controls Metasys
resident in the Danfoss VLT

2800 and VLT® 6000 Adjustable

N2 protocol
Frequency Drives. The BACLink port operates with an internal
ARCnet operating protocol. Recommended connection is through
EIA-485 compatible, half duplex, 9600 baud, shielded twisted-pair
wiring. Data points in the N2 database are classified as analog I/O
(floating point), binary I/O or integer data points. Each data type
has a unique structure defined in the Metasys N2 system Protocol
Specification for Vendors.

Mounting requirements
Wiring and terminal tightening specifications
Mount the BACLink enclosure as required using the predrilled
mounting holes (see Figure 2). The unit weighs approximately
15.3 pounds (7 kg).
For BACLink portals ordered without an enclosure, mount the unit
in an enclosed panel using the mounting holes provided on the
BACLink portal backplate (refer back to Figure 1). Leave about 2
inches (5 centimeters) on each side for wiring access. In addition,
the BACLink portal requires 24 VAC input power.
WARNING
!
BACLink portal is a Class 2 device (less
than 30VAC, 100VA maximum). Take
appropriate isolation measures when
mounting BACLink portal in control panels
where non-Class 2 devices (for example,
120V AC) or wiring are present.
Terminal tightening and wire specifications for the VLT2800 and
VLT 6000 are defined in Table I.
Total wiring length to connect up to 10 VLT 6000 and VLT 2800
drives from the BACLink portal should not exceed 3,000 feet
(900m) at 9600 baud rate.

Ethernet network connection
Procedure
The Ethernet network connects directly to the BACLink Ethernet
portal (refer back to Figure 1). The connection is a 10baseT port.
Both Ethernet and Ethernet IP (BACnet IP) connect through this
connector.
To establish Ethernet communication with the BACLink portal and
VLT drives, the following must be completed:
1. Wiring
2. Setting IP address of portal
3. For port 2 connection, setting port 2 configuration jumpers
Ethernet
Standard default
VLTÆ BACLink
1. Wiring
Wire Connections. Each BACLink portal can support up to 10
drives (see Figure 7). Any mix of VLT 2800 or VLT6000 drives is
supported.
The preferred portal-to-drive wiring is EIA-485 from port 2.
Connect portal Net+ to drive terminal 68 (+) and Net- to 69 (-).
Additional drives are connected pos-to-pos and neg-to-neg in
daisy chain fashion.
If required, port 1 can be factory-configured to connect the drives
through EIA-485.

NOTE
Steps 2 and 3 in the following connection
procedure may have already been factory-set
based upon customer ordering information.
Default IP address is 192.168.168.xxx.
Default subnet mask is 255.255.255.0.
Default gateway address is 0.0.0.0.
2. Set IP address of portal
C. Set BACLink portal address DIP switch. The BACLink
portal DIP switch 5 (refer back to Figure 8) must correspond to the
final portion of the IP address setting. Set the switch to +0 for
addresses 0to 99 or to +100 for addresses 100 to199.
3. Set configuration jumpers on portal
See the port connector label attached to the BACLink portal for the
factory-configured port assignments (refer back to Figure 1).
A. Set IP address to default or assigned. The BACLink portal
has either an internal default Internet Protocol (IP) address or a
factory-set IP address assigned from customer input. See the label
attached to the portal for the IP address in either case (refer back
to Figure 1). An IP address must always be present for Ethernet
IP network communication. Set the IP address DIP switch (switch
3 in Figure 8) on the BACLink portal as either default or assigned.

B. Set BACLink default address. The default IP address is
192.168.168.xxx. The xxx indicates the final portion of the IP
address which is set using the rotary switches on the BACLink
portal. The final portion of the address identifies the BACLink portal
with a unique address on the BACnet network. For example,
using the default address, Figure 9 shows the BACLink portal
address configured as 192.168.168.3. Set the user-assigned final
portion of the portal network address using the rotary switches.
Set port 2 configuration jumpers for communication type.
When using port 2 on the BACLink portal for communication with
the drives, set the port 2 configuration jumpers for EIA-485
(2-wire). Figure 10 illustrates the appropriate setting. EIA-485
(2-wire) is the factory default setting.

Power up
1. Turn BACLink power switch to OFF. This prevents
BACLink from power up before proper voltage is verified.
3. For VLT 6000, termination DIP switches 2 and 3 should be
in the ON position. Termination DIP switches are located on
VLT 6000 power board directly above drive terminals
where connections to terminals 68 and 69 are made.
2. Ensure that power is applied to the drives.
3. Plug connector from transformer to BACLink 24 VAC
power terminal.
4. Ensure that 24 VAC is present at BACLink power input
terminals.
5. Turn BACLink power switch to ON. Power, Run and Error
LEDs turn on. Run and Error LEDs then begin blinking.
Error LED turns off.
Troubleshooting drive communication
For use in the event of trouble communicating with the drives. Test
conditions for BACLink portal communications:
1. Test only one drive connected to portal at a time.
2. Portal power OFF.

TableV for test results.)
Troubleshooting Ethernet communication
With the BACLink portal connected to BACnet network through the
Ethernet connector, apply power to BACLink portal and switch
portal ON. See Table VI for test results.
Loss of signal recovery time
When serial communication is lost to the drive, recovery time to
reestablish communication with the network can take up to
5minutes.
Reverse wires to drive terminals 68
(+) and 69 (-) or remove short.
•
Apply power to drive.
•

•
Set drive address in

portal address (displayed on the IP
address label on the unit) and press
enter. If communicating, you will get a
reply. If not communicating, you will get
no response indication.
