Using the cable clamp included in the delivery of the drive, ground the shield of
the RS485 cable to the frame of the AC drive.

If drive is the last device on the bus, the bus termination must be set. Locate
the DIP switches to the right of the control keypad of the drive and turn the switch
for the RS485 bus termination resistor to position ON. Biasing is built in the ter-
mination resistor. See also step 9 on page 13.
