Basic Safety Instructions
Operating states and operating positions
The product may be operated only under the operating conditions and in the positions specified by the
manufacturer, without the product's ventilation being obstructed. 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. 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, use only
indoors, max. operating altitude 2000 m above sea level, max. transport altitude 4500 m above sea
level. A tolerance of ±10 % shall apply to the nominal voltage and ±5 % to the nominal frequency,
overvoltage category 2, pollution degree 2.
2. Do not place the product on surfaces, vehicles, cabinets or tables that for reasons of weight or stability
are unsuitable for this purpose. Always follow the manufacturer's installation instructions when
installing the product and fastening it to objects or structures (e.g. walls and shelves). An installation
that is not carried out as described in the product documentation could result in personal injury or
even death.
3. 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
even death.
Electrical safety
If the information on electrical safety is not observed either at all or 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 product
matches the nominal voltage of the mains-supply network. If a different voltage is to be set, the power
fuse of the product may have to be changed accordingly.
2. In the case of products of safety class I with movable power cord and connector, operation is
permitted only on sockets with a protective conductor contact and protective conductor.
3. Intentionally breaking the protective conductor 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.
4. If there is no power switch for disconnecting the product from the mains, or if the power switch is not
suitable for this purpose, use the plug of the connecting cable to disconnect the product from the
mains. In such cases, always ensure that the power plug is easily reachable and accessible at all
times. For example, if the power plug is the disconnecting device, the length of the connecting cable
must not exceed 3 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,
the disconnecting device must be provided at the system level.
5. Never use the product if the power cable is damaged. Check the power cables on a regular basis to
ensure that they are in proper operating condition. 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, for example, tripping over the cable or suffering an electric shock.
1171.0000.42 - 09 Page 3
Basic Safety Instructions
6. The product may be operated only from TN/TT supply networks fuse-protected with max. 16 A (higher
fuse only after consulting with the Rohde & Schwarz group of companies).
7. Do not insert the plug into sockets that are dusty or dirty. Insert the plug firmly and all the way into the
socket provided for this purpose. Otherwise, sparks that result in fire and/or injuries may occur.
8. Do not overload any sockets, extension cords or connector strips; doing so can cause fire or electric
shocks.
9. For measurements in circuits with voltages V
> 30 V, suitable measures (e.g. appropriate
rms
measuring equipment, fuse protection, current limiting, electrical separation, insulation) should be
taken to avoid any hazards.
10. Ensure that the connections with information technology equipment, e.g. PCs or other industrial
computers, comply with the IEC 60950-1 / EN 60950-1 or IEC 61010-1 / EN 61010-1 standards that
apply in each case.
11. 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.
12. If a product is to be permanently installed, the connection between the protective conductor terminal
on site and the product's protective conductor must be made first before any other connection is
made. The product may be installed and connected only by a licensed electrician.
13. For permanently installed equipment without built-in fuses, circuit breakers or similar protective
devices, the supply circuit must be fuse-protected 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.
14. 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.
15. 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.
16. 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.
17. Never use the product under conditions in which condensation has formed or can form in or on the
product, e.g. if the product has been moved from a cold to a warm environment. Penetration by water
increases the risk of electric shock.
18. 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.
1171.0000.42 - 09 Page 4
Basic Safety Instructions
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/Environmental protection",
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.
7. Laser products are given warning labels that are standardized according to their laser class. Lasers
can cause biological harm due to the properties of their radiation and due to their extremely
concentrated electromagnetic power. If a laser product (e.g. a CD/DVD drive) is integrated into a
Rohde & Schwarz product, absolutely no other settings or functions may be used as described in the
product documentation. The objective is to prevent personal injury (e.g. due to laser beams).
8. EMC classes (in line with EN 55011/CISPR 11, and analogously with EN 55022/CISPR 22,
EN 55032/CISPR 32)
Class A equipment:
Equipment suitable for use in all environments except residential environments and environments
that are directly connected to a low-voltage supply network that supplies residential buildings
Note: Class A equipment is intended for use in an industrial environment. This equipment may
cause radio disturbances in residential environments, due to possible conducted as well as
radiated disturbances. In this case, the operator may be required to take appropriate measures to
eliminate these disturbances.
Class B equipment:
Equipment suitable for use in residential environments and environments that are directly
connected to a low-voltage supply network that supplies residential buildings
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.
1171.0000.42 - 09 Page 5
Basic Safety Instructions
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, protective 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. Cells and batteries must not be exposed to any mechanical shocks that are stronger than permitted.
5. 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.
6. 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.
7. 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.
8. Follow the transport stipulations of the carrier (IATA-DGR, IMDG-Code, ADR, RID) when returning
lithium batteries to Rohde & Schwarz subsidiaries.
Transport
1. The product may be very heavy. Therefore, the product must be handled with care. In some cases,
the user may require a suitable means of lifting or moving the product (e.g. with a lift-truck) to avoid
back or other physical injuries.
2. Handles on the products are designed exclusively to enable personnel to transport the product. It is
therefore not permissible to use handles to fasten the product to or on transport equipment such as
cranes, fork lifts, wagons, etc. The user is responsible for securely fastening the products to or on the
means of transport or lifting. Observe the safety regulations of the manufacturer of the means of
transport or lifting. Noncompliance can result in personal injury or material damage.
