3.3.3 General Safety Instructions
The following safety instructions have been included in compliance with
safety standard regulations. Please read them carefully.
• READ AND RETAIN INSTRUCTIONS - Read all safety and operating
instructions before operating the instrument. Retain all instructions for
future reference.
• HEED WARNINGS - Adhere to all warnings on the instrument and
operating instructions.
• FOLLOW INSTRUCTIONS - Follow all operating and use instructions.
• WATER AND MOISTURE - Do not use the instrument near water.
• VENTILATION - The instrument should be used/installed only in locations
where the flow of air through the ventilation openings is not impeded.
• MOUNTING – The instrument can be used in Horizontal or vertical
orientation as long as the ventilation holes are not obstructed and the
protective grounding is not defeated.
• HEAT - The instrument should be situated away from heat sources such as
heat registers or other instruments which produce heat.
• POWER SOURCES - Connect the instrument only to the type of power
source described in the operating instructions or as marked on the
instrument.
• GROUNDING - Take precautions to insure that the grounding of the
instrument is not defeated. Grounding conductor with adequate cross-
section must be connected between a grounding conductor connection
for the measurement area and the grounding conductor connection
(grounding bolt) on the back panel of the LISN and the LISN bottom plate,
before applying any power to the LISN. At shutdown or before dismantling
the LISN setup, ensure that the power to LISN is discontinued before the
ground conductor connection is disconnected.
• CAUTION - The specified minimum line to ground capacitance induces
leakage currents in excess of the value permitted under EN 61010-1
standard – safety requirements for electrical equipment for measurement,
control and laboratory use.
In addition, the basic insulation required for a category I protection
device cannot be assured. Therefore it is imperative to provide additional
measures safeguarding against direct or indirect contact by user.
The operator is responsible for ensuring that protection is maintained
during work with the line impedance stabilization network (LISN).
Before using the LISN, a secure ground connection must be made to the
LISN grounding bolt and/or the bottom metal plate (The bottom surface
of the LISN is left unpainted for effective ground connection). It must not
be removed until after the LISN has been disconnected from the mains
power supply, in order to avoid electric shock.
The safety notes in the accompanying operating instructions and on the
outside of the device must be followed at all times.

4.0 LISN Installation
4.1 LISN Theory
The LI-3P-1x Series Line Impedance Stabilization Networks are specifically
designed to provide the necessary measurement platform for power line
conducted emissions (disturbance measurements) compliance testing as
required for FCC regulations, CISPR/EN/ETSI and other worldwide standards for
commercial products. The LISNs are fully compliant with the requirements of both
CISPR 16-1-2 and ANSI C63.4.
Line Impedance Stabilization Networks provide standardized line impedance to
the EUT during conducted emissions testing which is independent of the external
power line impedance. The standardized impedance enables consistent
readings for RF noise measurements on the power line.
In addition to providing a standardized impedance, the LISN also acts as a low
pass filter for the power to equipment under test. The LISN provides isolation
between the power source or mains network in order to reduce the amplitude of
unwanted ambient signals/noise while allowing the power to pass with minimal
voltage drop. This filter is comprised of a single stage low pass LC filter. The
inductor (L) used in the all Com-Power LISNs are air core type to eliminate the
possibility of saturation and to provide stability.
The LISN also provides a low impedance, capacitively coupled, minimal loss path
for the RF noise from each EUT power conductor to the measurement port. The
loss incurred along each of these paths is referred to as Insertion Loss. Insertion
Loss factors are individually measured and provided for each line in the network.
These factors must be considered in order to achieve the highest measurement
accuracy. The insertion loss factors (in dB) are added to the measured values (in
dBμV). A basic example schematic of the LISN is illustrated in Figure 4 below.

REV083017
4.2 Safety Considerations
It is critical that the LISN be installed in a manner which ensures that EACH of
following conditions are satisfied:
• The metal enclosure of the LISN must be connected to the reference ground
plane of the site. The recommended connection method is via a direct,
surface to surface connection between the LISN base plate and an exposed,
conductive surface of the floor or wall of a shielded enclosure. The LISN base
plate should be bolted to the surface using the mounting holes on the front
and back of the LISN base plate.
Where installation as described in the previous paragraph is not possible, the
LISN may be connected to earth ground via the ground lug located on the
rear panel of the LISN. Thick metallic braid or heavy gauge wiring is
recommended, and the length shall be kept as short as possible.
In cases where no ground plane is available, a mains isolating transformer
shall be used.
Please refer to the safety instructions in section 3.3 for more information on the
importance of grounding. The grounding instructions are to be followed at all
times.
• The ventilation openings in the LISN enclosure must be unobstructed.
• No signal or operating voltages/currents shall exceed those specified in the
product specifications listed in section 3.5.
• The LISN power input port must connected to an appropriate power source
protected by a circuit breaker with a current rating which is greater than or
equal to the rating of the LISN.
Due to the high level of earth leakage current, the device cannot be
connected to any power source protected by a Ground Fault Circuit
Interrupter (GFCI), also called Ground Fault Interrupter (GFI) or Residual
Current Device (RCD).
Failure to comply with any of these points may damage the equipment and/or
pose an electrical hazard.

4.3 Test Equipment Setup and Connections
Illustrated in Figure 5 below is an example of a typical test setup for conducted
emissions testing for an LI-3P-1x Series LISN.
FIGURE 5 - Example Test Equipment Setup/Connections
Depending on the electromagnetic environment, the use of a shielded
enclosure, power line filters and/or isolation transformers may or may not be
necessary. The LISN will act as a filter, providing greater than 40 dB of isolation
between the Mains Port and EUT Port. However, this may not be sufficient for
some installations, and additional power line filtration may prove to be necessary.
The standard CISPR 16-1-2 requires the use of a 10 dB attenuation pad between
the LISN measurement port and the measuring instrument in order to assure
accurate termination. The VSWR of the input and output port of the attenuation
pad shall be less than or equal to 1.2:1. Com-Power Transient Limiters incorporate
two 5 dB attenuation pads; thereby satisfying the 10 dB requirement. The
transient limiters comply with the 1.2:1 VSWR requirement, as well.
Using a transient limiter will also protect the RF input of your EMI receiver or
spectrum analyzer, which are extremely sensitive, and easily damaged by high
voltage transients. In addition, Com-Power Transient Limiters also incorporate
both a low pass and high pass filter to further attenuate out of band signals,
thereby reducing the possibility of RF overload.
Transient Limiters and 10 dB attenuation pads are available from Com-Power.
