(see Figure 4) are used to configure the drive for BACnet serial
bus termination. The switch position shown is the factory setting.
See Table II for setting information. The DIP switch are located
directly above terminals 61, 68 and 69 on the board.

VLT 6000 network wiring
1. Connect signal wires to drive terminal 68 (P+) and terminal
69 (N-) on main control board of drive (see figure 5).
2. If shielded cabling is used, connect one end of shield to
terminal 61. This terminal is connected to ground via an
internal RC link.
For additional wiring guidelines, see the procedures for specific
network-type connections in this manual.
NOTE
It is highly recommended to use shielded,
twisted-pair wires to reduce electrical noise
on drive communications. Ensure that
drive is grounded properly according to
instructions in the drive manual.
SWITCH
SETTING
Switch 1
Reserved/No function
Switches 2 & 3
Used for terminating an EIA-485 interface. When
the drive is the first, last, or only device on a
network, switches 2 and 3 must be ON.
When the drive is in any other location on the
network, switches 2 and 3 must be OFF.
Switch 4
Not applicable with BACnet.
