related product documentation and the related product. The use of tags in connection
with unrelated products or documentation can result in misinterpretation and in
personal injury or material damage.
Operating states and operating positions
The product may be operated only under the operating conditions and in the positions
specified by the manufacturer. If the manufacturer's specifications are not observed,
this can result in electric shock, fire and/or serious personal injury or death. Applicable
local or national safety regulations and rules for the prevention of accidents must be
observed in all work performed.
1. The R&S FSH is protected against dripping water and dust (IP degree 51). Unless
otherwise specified, the following requirements apply to Rohde & Schwarz
products: predefined operating position is always with the housing floor facing
down, IP protection 2X, pollution severity 2, overvoltage category 2, use only in
enclosed spaces, max. operation altitude 4600 m above sea level, max. transport
altitude 12000 m above sea level. A tolerance of ±10% shall apply to the nominal

R&S FSH Basic Safety Instructions
1175.6590.12 - 02 Page iii
2. Do not place the product on heat-generating devices such as radiators or fan
heaters. The ambient temperature must not exceed the maximum temperature
specified in the product documentation or in the data sheet. Product overheating
can cause electric shock, fire and/or serious personal injury or death.
Electrical Safety
If the information on electrical safety is not observed either at all to the extent
necessary, electric shock, fire and/or serious personal injury or death may occur.
1. Prior to switching on the product, always ensure that the nominal voltage setting on
the power supply matches the nominal voltage of the AC supply network.
2. If the product does not have a power switch for disconnection from the AC supply
network, the plug of the connecting cable is regarded as the disconnecting device.
In such cases, always ensure that the power plug is easily reachable and
accessible at all times (corresponding to the length of connecting cable, approx.
2 m). Functional or electronic switches are not suitable for providing disconnection
from the AC supply network. If products without power switches are integrated into
racks or systems, a disconnecting device must be provided at the system level.
3. Never use the product if the power cable is damaged. Check the power cable on a
regular basis to ensure that it is in proper operating condition. By taking
appropriate safety measures and carefully laying the power cable, you can ensure
that the cable will not be damaged and that no one can be hurt by, for example,
tripping over the cable or suffering an electric shock.
4. The product may be operated only from TN/TT supply networks fused with max.
16 A (higher fuse only after consulting with the Rohde & Schwarz group of
companies).
5. Do not insert the plug into sockets that are dusty or dirty. Insert the plug firmly and
all the way into the socket. Otherwise, sparks that result in fire and/or injuries may
occur.
6. Do not overload any sockets, extension cords or connector strips; doing so can
cause fire or electric shocks.
7. For measurements in circuits with voltages Vrms > 30 V, suitable measures (e.g.
appropriate measuring equipment, fusing, current limiting, electrical separation,
insulation) should be taken to avoid any hazards.
8. Ensure that the connections with information technology equipment, e.g. PCs or
other industrial computers, comply with the IEC60950-1/EN60950-1 or IEC61010-
1/EN 61010-1 standards that apply in each case.
9. Unless expressly permitted, never remove the cover or any part of the housing
while the product is in operation. Doing so will expose circuits and components and
can lead to injuries, fire or damage to the product.
10. For permanently installed equipment without built-in fuses, circuit breakers or
similar protective devices, the supply circuit must be fused in such a way that
anyone who has access to the product, as well as the product itself, is adequately
protected from injury or damage.

R&S FSH Basic Safety Instructions
1175.6590.12 - 02 Page iv
11. Use suitable overvoltage protection to ensure that no overvoltage (such as that
caused by a bolt of lightning) can reach the product. Otherwise, the person
operating the product will be exposed to the danger of an electric shock.
12. Any object that is not designed to be placed in the openings of the housing must
not be used for this purpose. Doing so can cause short circuits inside the product
and/or electric shocks, fire or injuries.
13. Unless specified otherwise, products are not liquid-proof (see also section
"Operating states and operating positions", item 1. Therefore, the equipment must
be protected against penetration by liquids. If the necessary precautions are not
taken, the user may suffer electric shock or the product itself may be damaged,
which can also lead to personal injury.
14. Prior to cleaning the product, disconnect it completely from the power supply (e.g.
AC supply network or battery). Use a soft, non-linting cloth to clean the product.
Never use chemical cleaning agents such as alcohol, acetone or diluents for
cellulose lacquers.
Operation
1. Operating the products requires special training and intense concentration. Make
sure that persons who use the products are physically, mentally and emotionally fit
enough to do so; otherwise, injuries or material damage may occur. It is the
responsibility of the employer/operator to select suitable personnel for operating
the products.
2. Before you move or transport the product, read and observe the section titled
"Transport".
3. As with all industrially manufactured goods, the use of substances that induce an
allergic reaction (allergens) such as nickel cannot be generally excluded. If you
develop an allergic reaction (such as a skin rash, frequent sneezing, red eyes or
respiratory difficulties) when using a Rohde & Schwarz product, consult a
physician immediately to determine the cause and to prevent health problems or
stress.
4. Before you start processing the product mechanically and/or thermally, or before
you take it apart, be sure to read and pay special attention to the section titled
"Waste disposal", item 1.
5. Depending on the function, certain products such as RF radio equipment can
produce an elevated level of electromagnetic radiation. Considering that unborn
babies require increased protection, pregnant women must be protected by
appropriate measures. Persons with pacemakers may also be exposed to risks
from electromagnetic radiation. The employer/operator must evaluate workplaces
where there is a special risk of exposure to radiation and, if necessary, take
measures to avert the potential danger.
6. Should a fire occur, the product may release hazardous substances (gases, fluids,
etc.) that can cause health problems. Therefore, suitable measures must be taken,
e.g. protective masks and protective clothing must be worn.

R&S FSH Basic Safety Instructions

Repair and service
1. The product may be opened only by authorized, specially trained personnel.
Before any work is performed on the product or before the product is opened, it
must be disconnected from the AC supply network. Otherwise, personnel will be
exposed to the risk of an electric shock.
2. Adjustments, replacement of parts, maintenance and repair may be performed only
by electrical experts authorized by Rohde & Schwarz. Only original parts may be
used for replacing parts relevant to safety (e.g. power switches, power
transformers, fuses). A safety test must always be performed after parts relevant to
safety have been replaced (visual inspection, PE conductor test, insulation
resistance measurement, leakage current measurement, functional test). This
helps ensure the continued safety of the product.
Batteries and rechargeable batteries/cells
If the information regarding batteries and rechargeable batteries/cells is not observed
either at all or to the extent necessary, product users may be exposed to the risk of
explosions, fire and/or serious personal injury, and, in some cases, death. Batteries
and rechargeable batteries with alkaline electrolytes (e.g. lithium cells) must be
handled in accordance with the EN 62133 standard.
1. Cells must not be taken apart or crushed.
2. Cells or batteries must not be exposed to heat or fire. Storage in direct sunlight
must be avoided. Keep cells and batteries clean and dry. Clean soiled connectors
using a dry, clean cloth.
3. Cells or batteries must not be short-circuited. Cells or batteries must not be stored
in a box or in a drawer where they can short-circuit each other, or where they can
be short-circuited by other conductive materials. Cells and batteries must not be
removed from their original packaging until they are ready to be used.
4. Keep cells and batteries out of the hands of children. If a cell or a battery has been
swallowed, seek medical aid immediately.
5. Cells and batteries must not be exposed to any mechanical shocks that are
stronger than permitted.
6. If a cell develops a leak, the fluid must not be allowed to come into contact with the
skin or eyes. If contact occurs, wash the affected area with plenty of water and
seek medical aid.
7. Improperly replacing or charging cells or batteries that contain alkaline electrolytes
(e.g. lithium cells) can cause explosions. Replace cells or batteries only with the
matching Rohde & Schwarz type (see parts list) in order to ensure the safety of the
product.
8. Cells and batteries must be recycled and kept separate from residual waste.
Rechargeable batteries and normal batteries that contain lead, mercury or
cadmium are hazardous waste. Observe the national regulations regarding waste
disposal and recycling.
