Follow the cabling recommendations of the drive Hardware Manual.
Leave at least 0.5 m space between the unit and the power cables and drive
module. If 0.5 m is impossible, install as far as possible.
Use shielded twisted-pair cables between the transformers and the RSYC unit.
Ground the shields with as short pigtails as possible. Cut and insulate any unused
conductors at both ends of the cables. See Connection diagram.
Use shielded twisted-pair cables between the RSYC unit and the drive. Ground the
