output(s), etc.).
On the INTERFERING equipment
See common section.
(1) Ensure “LF” and “HF” equipotential bonding of exposed conductive parts.
Recommended
implementation (cont'd)
(See chapter 2)
(p. 8)
The power supply
(2) Avoid propagation of interference upstream of interfering equipment.
==> Use separate power supply lines and if necessary separate power sources to ensure
effective “HF” decoupling (double screen transformer, filters, etc.).
See common section.
The equipment
(3) Limit the radiation of interfering equipment.
==> Assemble the equipment in housing(s) that provide(s) adequate shielding (cabinet,
casing, etc.)
See common section.
The associated cables
(4) Limit the flow of interference upstream of the installation:
==> Set up decoupling systems (R, L, C), ferrite cores or suitable filters on the inputs and/
or outputs of the devices.
See common section.
