Manual 1178.9932.02 ─ 01
Take the following measures for your safety:
●
Use double-insulated connecting cables with characteristics suitable for the appli-
cation:
–
Appropriate minimum cross-section.
–
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 LISN's
power connector 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.
Using accessories
Select accessories that are suitable for the instrument and the measurement task,
especially if they are not manufactured by Rohde
&
Schwarz.
Measurement accessories such as current clamps or artificial hands must comply with
the measurement category of your test setup.
Cleaning the product
Use a dry, lint-free cloth to clean the product. When cleaning, keep in mind that the
casing is not waterproof. Do not use liquid cleaning agents.
Meaning of safety labels
Safety labels on the product warn against potential hazards.
