4.1

Connecting the Drive to the Network

Before connecting the drive to the network, verify that the module has been installed
in the drive according to the instructions provided in chapter 3. Then use the following
procedure to connect the drive to the network:

Step 1. Verify that power is removed from the network and drive.

Step 2. Use static control procedures.

Step 3. Route the network cable through the bottom of the drive (or as described in

the VTAC 7 User Manual). Refer to table 2.2 in chapter 2 for recommended
network cables.

Step 4. Connect the network cable to the 5-screw terminal block on the LonWorks

module. Refer to table 4.1 for the terminal definitions.

4.2

Terminating the Network

The LonWorks module does not provide built-in termination. Refer to the FTT-10A
Free Topology Transceiver User’s Guide (doc.id078-0156-01F) for more information
about terminating a LonWorks network (available at http://www.echelon.com).

ATTENTION: The drive may contain high voltages that can cause injury
or death. Remove all power from the drive, then verify power has been
removed before installing or removing a LonWorks module. Failure to
observe these precautions could result in severe bodily injury or loss of
life.
