1. The product may be operated only
under the operating conditions and in
the positions specified by the
manufacturer. Its ventilation must not
be obstructed during operation.
Unless otherwise specified, the
following requirements apply to
Rohde & Schwarz products:
prescribed 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 max. 2000 m.
Unless specified otherwise in the
data sheet, a tolerance of ±10% shall
apply to the nominal voltage and of
±5% to the nominal frequency.
2. Applicable local or national safety
regulations and rules for the
prevention of accidents must be
observed in all work performed. The
product may be opened only by
authorized, specially trained
personnel. Prior to performing any
work on the product or opening the
product, the product must be
disconnected from the supply
network. Any adjustments,
replacements of parts, maintenance
or repair must be carried out only by
technical personnel authorized by

Safety Instructions
1171.0000.52-02.00 Sheet 3
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).
3. As with all industrially manufactured
goods, the use of substances that
induce an allergic reaction (allergens,
e.g. nickel) such as aluminum cannot
be generally excluded. If you develop
an allergic reaction (such as a skin
rash, frequent sneezing, red eyes or
respiratory difficulties), consult a
physician immediately to determine
the cause.
4. If products/components are
mechanically and/or thermically
processed in a manner that goes
beyond their intended use, hazardous
substances (heavy-metal dust such
as lead, beryllium, nickel) may be
released. For this reason, the product
may only be disassembled, e.g. for
disposal purposes, by specially
trained personnel. Improper
disassembly may be hazardous to
your health. National waste disposal
regulations must be observed.
5. If handling the product yields
hazardous substances or fuels that
must be disposed of in a special way,
e.g. coolants or engine oils that must
be replenished regularly, the safety
instructions of the manufacturer of
the hazardous substances or fuels
and the applicable regional waste
disposal regulations must be
observed. Also observe the relevant
safety instructions in the product
documentation.
6. Depending on the function, certain
products such as RF radio equipment
can produce an elevated level of
electromagnetic radiation.
Considering that unborn life requires
increased protection, pregnant
women should be protected by
appropriate measures. Persons with
pacemakers may also be endangered
by electromagnetic radiation. The
employer is required to assess
workplaces where there is a special
risk of exposure to radiation and, if
necessary, take measures to avert
the danger.
7. Operating the products requires
special training and intense
concentration. Make certain that
persons who use the products are
physically, mentally and emotionally
fit enough to handle operating the
products; otherwise injuries or
material damage may occur. It is the
responsibility of the employer to
select suitable personnel for
operating the products.
8. Prior to switching on the product, it
must be ensured that the nominal
voltage setting on the product
matches the nominal voltage of the
AC supply network. If a different
voltage is to be set, the power fuse of
the product may have to be changed
accordingly.
9. In the case of products of safety class
I with movable power cord and
connector, operation is permitted only
on sockets with earthing contact and
protective earth connection.
10.Intentionally breaking the protective
earth connection either in the feed
line or in the product itself is not
permitted. Doing so can result in the
danger of an electric shock from the
product. If extension cords or
connector strips are implemented,
they must be checked on a regular
basis to ensure that they are safe to
use.

Safety Instructions
1171.0000.52-02.00 Sheet 4
11.If the product has no power switch for
disconnection from the AC supply,
the plug of the connecting cable is
regarded as the disconnecting
device. In such cases, it must be
ensured that the power plug is easily
reachable and accessible at all times
(length of connecting cable approx.
2 m). Functional or electronic
switches are not suitable for providing
disconnection from the AC supply. If
products without power switches are
integrated in racks or systems, a
disconnecting device must be
provided at the system level.
12.Never use the product if the power
cable is damaged. By taking
appropriate safety measures and
carefully laying the power cable,
ensure that the cable cannot be
damaged and that no one can be hurt
by e.g. tripping over the cable or
suffering an electric shock.
13.The product may be operated only
from TN/TT supply networks fused
with max. 16 A.
14.Do not insert the plug into sockets
that are dusty or dirty. Insert the plug
firmly and all the way into the socket.
Otherwise this can result in sparks,
fire and/or injuries.
15.Do not overload any sockets,
extension cords or connector strips;
doing so can cause fire or electric
shocks.
16.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.
17.Ensure that the connections with
information technology equipment
comply with IEC 950/EN 60950.
18.Never remove the cover or part of the
housing while you are operating the
product. This will expose circuits and
components and can lead to injuries,
fire or damage to the product.
19.If a product is to be permanently
installed, the connection between the
PE terminal on site and the product's
PE conductor must be made first
before any other connection is made.
The product may be installed and
connected only by a skilled
electrician.
20.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 suitable protection is
provided for users and products.
21.Do not insert any objects into the
openings in the housing that are not
designed for this purpose. Never pour
any liquids onto or into the housing.
This can cause short circuits inside
the product and/or electric shocks,
fire or injuries.
22.Use suitable overvoltage protection to
ensure that no overvoltage (such as
that caused by a thunderstorm) can
reach the product. Otherwise the
operating personnel will be
endangered by electric shocks.
23.Rohde & Schwarz products are not
protected against penetration of
water, unless otherwise specified
(see also safety instruction 1.). If this
is not taken into account, there exists
the danger of electric shock or
damage to the product, which can
also lead to personal injury.
24.Never use the product under
conditions in which condensation has
formed or can form in or on the
product, e.g. if the product was
moved from a cold to a warm
environment.
