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/front 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 LI-1100C
is based on the 50Ω/50 µH artificial mains network (AMN)
circuit and component values (Figure 3) specified in ANSI C 63.4

American National Standard for Methods of Measurement of Radio-
Noise Emissions from Low-Voltage Electrical and Electronic Equipment
in
the Range of 9 kHz to 40 GHz
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’s grounding bolt and/or the bottom metal pl
ate (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.
•
POWER CORD PROTECTION
- Place power supply cords so that they are
not likely to be walked on or pinched by items placed on them or
against them.
•
CLEANING
–
Clean the instrument outside surfaces of the device with a
soft, lint-free cloth. If necessary, a mild detergent may be used.
•
NON-USE PERIODS
- Unplug the power cords of the instrument when it will
be left unused for a long period of time.
•
OBJECT AND LIQUID ENTRY
- Take care that objects do not fall into the
instruments and that liquids are not spilled into the enclosure through
openings.
