BACLink accesses the Johnson Controls Metasys ® N2 protocol VLT ® is a Danfoss registered trademark. resident in the Danfoss VLT ® 2800 and VLT ® 6000 Adjustable 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.

VLT 6000 are defined in Table I. 15.3 pounds (7 kg). Total wiring length to connect up to 10 VLT 6000 and VLT 2800 For BACLink portals ordered without an enclosure, mount the unit drives from the BACLink portal should not exceed 3,000 feet in an enclosed panel using the mounting holes provided on the (900m) at 9600 baud rate.
1. Power must be supplied to the 115 VAC outlet from an external source (see Figure 3). 2. Plug transformer into 115 VAC outlet. 3. Connect transformer cable to 24 VAC connector on BACLink board. Figure 3. BACLink Enclosure Electrical Components VLT is a registered Danfoss trademark...

Power up 3. For VLT 6000, termination DIP switches 2 and 3 should be in the ON position. Termination DIP switches are located on 1. Turn BACLink power switch to OFF. This prevents VLT 6000 power board directly above drive terminals BACLink from power up before proper voltage is verified.
NOTE Binary input point 9 commands two different functions. For VLT 2800, it commands reverse function to change direction of motor rotation. For VLT 6000, it can command the state of Form C relay. VLT is a registered Danfoss trademark...
