performance. The selected cable must have a temperature rating that is
adequate for the expected operating temperature of the motor case.
All cables must maintain high-integrity 360° shielding. Do not use drain
wires to terminate shields. If shields cannot be properly terminated
within the connector shell, utilize a conductive R-clamp to terminate the
shield to chassis ground as close to the cable end as possible. This
requires carefully exposing ½ to ¾ inch of the cable shields as shown in
Figure 43 on page 105.
Whe
n you install limit switches and other inputs/outputs, you must
observe these same noise immunity procedures and practices.
• Route cables as shown in Figure 44 on page 109.
Route hi
gh power cables (motor and mains) at right angles to low power
cables (communications and inputs/outputs). Never route high and low
power cables parallel to each other.
Mount filters close to the drive/controller and keep the supply wiring as
short as practical. Attempt to layout the wiring in a way that minimizes
cross coupling between filtered and non-filtered conductors. This means
avoiding running wires from the output of a filter close to those
connected to its input. Where you wish to minimize the cross coupling
between wires avoid running them side-by-side one another, if they
must cross, cross them at 90° to each other. Use cable fasteners to
keep wiring supported and close to cabinet metalwork.
• Cables may require the use of ferrite core suppressors.
Some installations may require that you take additional EMC measures.
To further increase product immunity and reduce product emissions,
you may add clip-on ferrite absorbers to all cables. Parker recommends
ferrites with at least 200 ohm impedance at 100 MHz, such as the
following:
Make Part Number
Steward Ferrite 28A2024
Fair-Rite 0443164151
Note: These ferrites are also available from Parker Hannifin, part number
47-015956-01. For larger diameter cables (up to 0.722 in O.D.), Fair-Rite part
number 0444176451 is recommended.

• Your Installation may require additional EMC installation hardware (as
shown in illustrations).
The following clamp kits are available from Parker:
Clamp Type Parker Part Number
R-Clamp Kit (10 per) R CLAMP KIT
Clamshell Clamp Kit (2 per) CLAMSHELL KIT
Table 43 Enclosure Mounting Clamps
Note: The Control power input also requires a mains power line filter,
varistors, and fuses in order to comply with the relevant CE directives.
