Shielding
Any wire or cable assembly entering or exiting the S2000 may act like an antenna
which will pick up noise and transmit it to the internal electronics. This may cause
the S2000 to operate erratically.
There are several ways in which the S2000 can be shielded (protected). Lumen
Dynamics recommends the use of shielded cables for all cable assemblies: the AC
line cord, the I/O cables and the foot switch. Furthermore, it is advised that clamp-
on ferrite shield beads be added to every cable assembly. Suitable ferrite shield
beads are: P/N: 0443164251 by Fair-Rite Products Corp. (or) P/N: 28A2025-0A0
by Steward.
Noise suppression products are also available in the form of AC power bars that
incorporate surge suppression and noise suppression circuitry. Either type will help
in protecting the S2000 from noise. Providing the S2000 with an AC line that is
separate from any other noise producing equipment will also be beneficial.
Depending on the noise Level in the environment, any combination or all of the
above shielding recommendations may be necessary to protect the S2000 from
noise and ensure smooth operation. We can help you to shield the S2000 from
electrical noise. Please contact
