R&S ENV4200
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.
