Control cables
Twisted-Pair shielded
cables for analog
control and motor
feedback signals.
Cable shield exposed
and 360° clamped to
grounded metal plate or PE
bar. All other 360° bonding
methods are acceptable.
Motor cable
3-phase and PE shielded cable.
Maintain shield as far as
possible along the cable
