The NEO Install Kit contains additional ferrite core, which can be applied to the Power
Supply at the AC/DC Adapter side on the DC cable (see below). The ferrite at the power
supply side is optional.
7.4.2 Optional Ferrite on DC Cord near PSU AC/DC Adapter
Although not required for FCC or ETSI compliance, the ferrite core shown below is
considered "optional." When the DC cord seems to be causing "noise" then applying any
of these types of ferrite cores may mitigate the noise conditions.
Figure 13: Common Ferrites
1 Ferrite Core is provided in the installation kit, however this ferrite is typically not
needed (see section 4.6.2 describing its intended use).
Figure 14: Optional Ferrite Core Placement, Near PSU Adapter
Shown above, the "Multi-Purpose Ferrite Core" (CKP P/N 7284760) is suitable to be used
here. Figure 13 shows other types which can be used. You can apply this (or any) ferrite
core with 4 turns near the DC output as shown.
