Wiring for connecting an external operating panel
To use an external operating panel, connect one end of the connecting cable to the
RJ45 port of the AC drive, and lead the other end of the cable out to the operating
panel from either side of the AC drive, as shown in "

7.4.3 Requirements on Selection and Routing of Control Circuit Cables
Note
Connect the control circuit cables according to EN 60204‑1.
Selection requirements
To prevent peripheral interference and noise, use shielded cables for the control
circuit. Install a shielding bracket at each end of the shield layer to reliably connect
the cable to the AC drive. Use a separate shielded cable for each type of analog signal.
Use shielded twisted pair cables for digital signals.

Requirements on shield grounding for analog terminals
Weak analog voltage signals are susceptible to external interference. Therefore, a
shielded cable is typically required, and the wiring distance should be as short as
