LISNs are designed according to CISPR 16-1-2 (EN 55016-1-2) and do not meet the
permissible limit for the leakage current as defined in EN 61010-1. In addition, LISNs
do not provide basic insulation, rated as measurement category II (protection class 1).
Therefore, only connect, set up and use LISNs if you are an electrically skilled person.
Electrically skilled persons have the relevant education and experience to enable them
to perceive risks and to avoid hazards that electricity can cause.
These users also need sound knowledge of at least one of the languages in which the
user interfaces and the product documentation are available.
LISNs can pose hazardous and even life-threatening risks:
●Electrical shock because of a high leakage current and live parts if the LISN is not
grounded.
●Electrical shock because the LISN does not have a fuse in the measuring circuit.
●Burns and fire hazard caused by overheating of the housing. Overheating can
occur if the ventilation is insufficient or if the cables' cross-section is too small.
If any part of the LISN is damaged or broken, stop using the LISN. Never open the cas-
ing of the LISN. Only service personnel authorized by Rohde & Schwarz are allowed to
repair the LISN. Contact Rohde & Schwarz customer service at http://www.rohde-
schwarz.com/support.
Lifting and carrying the product
Look up the weight in the data sheet. If the product is heavy, you cannot move or carry
it on your own. A single person can only carry a maximum of 18 kg safely, depending
on age, gender and physical condition. To move the product safely, you can also use
lifting or transporting equipment such as lift trucks or forklifts. Follow the instructions
provided by the lifting or transporting equipment manufacturer.
Choosing the operating site
Only use the LISN indoors in rooms equipped with a protective earth connection (for
example EMC test rooms). The product casing is not waterproof and water that enters
the casing can electrically connect the casing with live parts. This can lead to electric
shock, serious personal injury or death if you touch the casing.
You can operate the product up to an altitude of 2000 m above sea level. The product
is suitable for pollution degree 2 environments where nonconductive contamination can
occur.
For more information on environmental conditions such as ambient temperature and
humidity, see the data sheet.
Setting up the product
Always place the LISN on a stable, flat and level surface with the bottom of the LISN
facing down. Make sure that the air supply is not obstructed from any side.
Place the LISN on a nonflammable base, for example, a metal plate, to prevent a fire if
the ventilation system fails or if it gets too hot.
If the LISN has foldable feet, always fold the feet completely in or out to ensure stabil-
ity. The feet can collapse if they are not folded out completely or if the LISN is moved

without lifting it. The foldable feet are designed to carry the weight of the LISN, but not
an extra load.
Observe the applicable national regulations and standards as part of the installation
process.
Protective ground connection
Always establish a protective ground connection before connecting the LISN to a
power source. A protective ground protects you from electrically live parts on the cas-
ing caused by high leakage currents. High leakage currents can cause electric shock,
serious personal injury or death if you touch the casing.
●Only use ground cables that have a sufficient cross-section that complies with
VDE 0100-540 part 5-54 (IEC 60364-5-54).
●Validate that the ground connection is safe.
●The ground connection must remain until you have disconnected the LISN from the
power source.
●If the LISN has an auxiliary voltage, secure the test setup with a second protective
ground. The second ground connection protects you from live parts if the ground
connection of the auxiliary cable fails.
Connecting to power
The product is an overvoltage category II product and has to be connected to a fixed
installation used to supply energy-consuming equipment such as household applian-
ces and similar loads. Electrically powered products have risks, such as electric shock,
fire, personal injury or even death.
Observe the protective measures given by VDE 0100-410 (IEC60364-4-41) while
working with the LISN.
Take the following measures for your safety:
●Use double-insulated connecting cables with an appropriate minimum cross-sec-
tion and an appropriate minimum voltage rating.
Select the cable based on the maximum power consumption of the device under
test, the fuse rating of the building installation and the cable length. When installing
the supplied cable sockets, observe the assembly instructions and the require-
ments of the manufacturer.
●By design, LISNs do not have a fuse in the measuring circuit. Therefore, you have
to make sure that the operating circuit between the power supply and the power
connector of the LISN is fused correctly.
●Only use the power cable delivered with the product. It complies with country-spe-
cific safety requirements.
●Only use intact cables and route them carefully so that they cannot be damaged.
Check the power cables regularly to ensure that they are undamaged. Also ensure
that nobody can trip over loose cables.
●Only connect the product to a power source with a maximum fuse protection
according to the datasheet.

●Ensure that you can disconnect the product from the power source at any time.
Pull the power plug to disconnect the product. The power plug must be easily
accessible. If the product is integrated into a system that does not meet these
requirements, provide an easily accessible circuit breaker at the system level.
●If the LISN has an auxiliary voltage: Before taking the LISN auxiliary voltage into
operation, ensure that the voltage and frequency indicated on the product match
the available power source. If the values do not match, contact Rohde & Schwarz
customer service.
If the ventilation system is powered by an auxiliary voltage, always connect the
auxiliary voltage before taking the LISN into operation. Operation without the venti-
lation system leads to overheating and can cause a fire.
●If the LISN can be powered by an external power supply, make sure that the power
supply complies with the requirements for reinforced/double insulation in accord-
ance with DIN/EN/IEC/UL/CSA 61010-1, DIN/EN/IEC/UL/CSA 60950-1 or
DIN/EN/IEC/UL/CSA 62368-1.
Using accessories
Select accessories that are suitable for the product and the measurement task, espe-
cially if they are from 3rd party manufacturers.
Measurement accessories, such as current clamps or artificial hands must comply with
