Unless already done for the other control cables,
cut free the opening on the AC drive cover for
the RS485 cable (protection class IP21).

Remount the AC drive cover and run the RS485
cables as shown in picture.
NOTE: When planning the cable runs, remem-
ber to keep the distance between the fieldbus
cable and the motor cable at a minimum of 30
cm.

The bus termination must be set for the first and the last device of the fieldbus
