MODEL LFIL - GENERAL PURPOSE LINE FILTER
Bulletin No. LFIL-A
Drawing No. LP0380
Released 02/12
DESCRIPTION
This line filter can be used in AC or DC power supply lines to attenuate
conducted Electro-Magnetic Interference (EMI). EMI is the most common
cause of erratic operation in electronic equipment. Line filters should be
installed close to electronic equipment and mounted directly to a metal
enclosure that is connected to earth ground (protective earth).
Note: Always connect the earth lead of the filter to the power line ground
(protective earth).
METAL ENCLOSURE

Figure 1
The ideal location for the line filter is directly inside the metal enclosure in
which the unit is mounted when the source of EMI is external to the enclosure
(See Figure 1). Mount the filter where the power enters the enclosure. If the
enclosure contains many different types of equipment or EMI generating
devices, such as motors or contactors, then the EMI source may be inside the
enclosure. In this case, mount the line filter as close to the unit as possible (See
Figure 2).

Figure 2
If the panel and enclosure are non-conductive, then the power feed ground is
the only earth ground connection. Connecting only the earth lead of the filter to
the earth ground without mounting the filter directly to a metal enclosure will
not be as effective.
