Strip about 15 mm of the RS485 cable (see specification on page 7) and cut off
the grey cable shield. Remember to do this for both bus cables (except for the
last device).
Leave no more than 10 mm of the cable outside the terminal block and strip the
cables at about 5 mm to fit in the terminals. See picture below.
Also strip the cable now at such a distance from the terminal that you can fix it to
the frame with the grounding clamp. Strip the cable at a maximum length of 15
mm. Do not strip the aluminum cable shield!

Then connect the cable to its appropriate terminals on drive standard terminal
block, terminals A and B (A = negative, B = positive). See Figure 8.
