Clamp on cores illustrates the use of multiple turns through a
clamp-on core. The more turns created, the more impedance is
added to the line. Avoid putting the shield in a clamp-on core. It is
undesirable to place an impedance in-line with the shield. The use
of ribbon cable may be common in many cabinets. Some ferrite
clamps are designed just for ribbon cable use.

Note 1 Input power - Enters enclosure from metal conduit. This
eliminates the need for shielded input power cable.
Note 2 Single point ground. A bus bar (ground bus) is an
excellent way to achieve this.
Note 3 High frequency ground between non-conductive back
panel and enclosure. Also, a high frequency ground is
required between the enclosure and earth ground.
Note 4 Bonding of the motor cables. The use of armored
(screened) motor cables that are bonded as close to the
drive as possible is essential for CE compliance and
strongly recommended to better the overall performance
and reliability of the system.
Note 5 Screened and bonded feedback cabling is recommended
for increased immunity and lower risk of radiation. Since
the motor cable and feedback cable are in close proximity
near the motor, feedback cable bonding is necessary.
Also, separate the feedback and motor cables as much as
possible. This decreases the chances of the feedback
signals getting corrupted.
Note 6 Control signals (I/O) should be kept separate from all
power and motor cables. Keep all control wiring as short
as possible and use screened wire. A separation distance
of 20 cm (8 in) is sufficient in most cases. Where control
cables must cross power cables, they should cross at a
90º angle.
Note 7 Connect safety grounds to filters. This is critical to keep
ground currents from causing personal injury.
Note 8 Where motor cables exit enclosure, keep in separate wire-
way or conduit from feedback and other control wiring. A
separation distance of 20 cm. or 8 in. is sufficient.
Note 9 Input power wires should be kept clear of I/O and signal
wires.
