RS485 Cabling
1. Remove approximately 15 mm (0.59 in) of the gray shield of the RS485 cable. Do this for the two fieldbus cables.
A Strip the cables for approximately 5 mm (0.20 in) to put them in the terminals. Do not keep more than 10 mm (0.39 in) of the
cable outside the terminals.
B Strip the cable at such a distance from the terminal that it can be attached to the frame with the grounding clamp for the
control cable. Strip the cable at a maximum length of 15 mm (0.59 in). Do not remove the aluminum shield of the cable.
2. Connect the cable to the default I/O board of the drive, in terminals A and B.
• A = negative
• B = positive
3. Attach the shield of the cable to the frame of the drive with a grounding clamp for the control cable to make a grounding
connection.
