contact and connected protective conductor.
12System Manual 2506.5060.02 ─ 03
R&S®TLx9
Safety Instructions
General Safety Instructions
3. Intentional interruption of the protective conductor either along 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 cables or multipoint connectors are used, they
must be checked on a regular basis to ensure that they are safe to use.
4. If the product does not have a mains switch for disconnecting the product from the
power supply
, the plug attached to the connecting cable must be used as a disconnect device. In such cases, it must be ensured that the power plug is within easy
reach and accessible at all times (length of connecting cable approx. 2 m). Functional switches or electronic switches are not suitable for disconnecting the product
from the power supply. If products without mains switches are integrated in racks or
systems, a disconnect device must be provided at the system level.
5. 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. Take appropriate
safety measures and lay the power cable carefully to ensure that the cable will not
be damaged and that no one can be hurt by, for example, suffering an electric
shock or tripping over the cable.
6. Operation is only permitted in TN/TT supply networks which are fuse-protected with
max. 16 A (higher fuse ratings should only be used after consultation 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
completely into the socket provided. Disregard of these points can lead to sparks,
fire and/or injury.
8. Do not overload the sockets, extension cables or multipoint connectors as this can
cause fire or electric shocks.
9. For measurements in electric circuits with voltages V
> 30 V, suitable measures
rms
(e.g. appropriate measuring equipment, fusing, current limiting, electrical separation, insulation) must be taken to avoid any hazards.
10. In the case of connections to IT equipment (e.g. PCs or industrial computers), it
must be ensured that such connections satisfy the IEC60950‑1/EN60950‑1 or
IEC61010‑1/EN61010‑1 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 would expose electrical lines and components and could 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 qualified electrician.
13. 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.
13System Manual 2506.5060.02 ─ 03
R&S®TLx9
Safety Instructions
General Safety Instructions
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. Do not insert foreign objects into the housing openings. Doing so can cause short
circuits inside the product and/or electric shocks, fire or injuries.
Unless otherwise specified, products are not protected against the penetration of
16.
fluids; see also the section "Operating conditions, operating positions and operating locations", item 1. The instruments must therefore be protected against the
penetration of fluids. Failure to observe this point may result in the user suffering
an electric shock or the product being damaged, which in turn can endanger personnel.
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. mains or battery). Clean instruments using a damp, soft, lint-free paper towel
or cotton cloth. Warm water or a mild cleaner (good results have been achieved
using glass cleaner (Mat. No. 0041.5336.00)) is recommended as a cleaning
agent. If any other cleaning agent is to be used, it must be checked beforehand
whether the cleaning agent is compatible with the surface to be cleaned.
Operation
1. Operating the product requires special training and intense concentration. It must
be ensured that persons who operate the product are fit to do so from a physical,
intellectual and mental viewpoint, otherwise there is a risk of injury or damage. It is
the responsibility of the employer/operator to select suitable personnel for operating the product.
2. Before moving or transporting the product, read and observe the information in the
section "Transport" on page 16.
3. As with all industrially manufactured goods, it is not possible to completely rule out
the use of materials which cause allergies, i.e. "allergens" (e.g. nickel). If, when
using Rohde & Schwarz products, allergic reactions occur (e.g. skin rash, frequent
sneezing, red eyes or respiratory problems), consult a doctor immediately in order
to determine the cause and to prevent health problems.
4. Before mechanically and/or thermally processing or dismantling the product, it is
essential to refer to the section "Disposal" on page 16, item 1.
5. Depending on the function, certain products such as RF radio systems can produce an elevated level of electromagnetic radiation. In order to protect unborn life,
pregnant women must be protected by means of suitable measures. Electromagnetic radiation also poses a risk to persons with pacemakers. The employer/operator is obliged to assess and identify workplaces where there is a particular risk of
exposure to radiation, and to take precautions to prevent potential hazards.

General Safety Instructions
6. In the event of fire, toxic substances (gases, fluids, etc.) can be discharged from
the product and damage the health of personnel. If a fire occurs, appropriate measures must therefore be taken (e.g. breathing masks and protective clothing).
7. If a laser product is integrated in a Rohde & Schwarz product (e.g. CD/DVD drive),
no settings or functions other than those described in the product documentation
should be used in order to prevent injury (e.g. from the laser beam).
Repair and service
The product may be opened only by authorized, specially trained personnel. Before
1.
any work is performed on the product or before the product is opened, it must be
disconnected from the supply voltage, otherwise there is a risk of electric shock.
2. Any adjustments, part replacements, maintenance or repairs may be performed
only by authorized Rohde & Schwarz electricians. Only original parts may be used
for replacing safety-relevant parts (e.g. mains switches, power transformers,
fuses). A safety check must be performed after safety‑relevant parts have been
replaced (visual inspection, protective conductor test, insulation resistance measurement, leaking current measurement, functional test). This ensures that the
product remains safe to use.
Batteries and accumulators/cells
If the instructions regarding batteries and accumulators/cells are 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 even death. Batteries and accumulators with
alkaline electrolytes (e.g. lithium cells) must be handled in line with EN 62133.
1. Cells must not be disassembled, opened or crushed.
2. Cells and 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 terminals
using a dry, clean cloth.
3. Cells and 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. A cell or battery should
only be taken out of its original packaging when it is to be used.
4. Keep cells and batteries out of the reach of children. If a cell or battery has been
swallowed, seek medical assistance immediately.
5. Cells and batteries must not be subjected to severe mechanical jolts or impacts.
6. If a cell develops a leak, the fluid must not come into contact with the skin or eyes.
If contact occurs, wash the affected area with plenty of water and seek medical
assistance.
7. There is a risk of explosion if cells or batteries containing alkaline electrolyte
(e.g. lithium cells) are replaced or charged incorrectly. To ensure that the product

the product.
3. If you use the product in a vehicle, it is the responsibility of the driver to drive the
vehicle in a safe and appropriate manner. The manufacturer shall not accept liability for accidents or collisions. Never use the product in a moving vehicle if there is a
risk that this could distract the vehicle driver. Make sure that the product is adequately secured in order to prevent injury or other damage in the event of an accident.
Disposal
1. If products or their components are processed mechanically and/or thermally
beyond the scope of the operating conditions for which they were intended, hazardous materials (dust containing heavy metals such as lead, beryllium, nickel) can
be released. For this reason, the product may only be disassembled by specially
trained personnel. Improper disassembly may be hazardous to your health.
National waste disposal regulations must be observed.
2. If, when handling the product, hazardous materials or operating fluids are encountered which must be disposed of separately (e.g. coolant or engine oils that have to
be changed at regular intervals), the safety instructions from the manufacturer of
these hazardous materials and operating fluids, and the applicable local disposal
regulations must be observed. Also observe any additional relevant safety instructions in the product documentation. Incorrect disposal of hazardous materials or
operating fluids can result in damage to health and the environment.

2.3.1 Hazards from AC Supply Voltage
2.3.1.1 AC Power Supply
2.3 Special Hazard Information
All voltages of Urms > 30 V AC or U > 60 V DC must be regarded as constituting a
shock hazard. When working with voltages that constitute a shock hazard, appropriate
measures must be taken to prevent exposure to danger
nents. Work on live parts should only be performed in exceptional cases and only if
special safety precautions are taken.
●
Before connecting the AC power supply, it is important to ensure that the power
supply specifications given for the system or instruments match the nominal specifications for the local power supply network. The power supply circuit must be protected by means of fuses in order to prevent overloads and short circuits.
●
Miniature modules have neutral conductor fuses. As a result, the power supply
may still be connected even after interruption of the circuit by a fuse.

2.3.1.2 Changing Fuses
●
Fuses which are accessible to the operator should only be changed after the
instruments have been disconnected from the power supply. They must always be
replaced with fuses that have the same electrical rating, tripping characteristics and
breaking capacity.
●
Motor protection switches and automatic line fuses in those parts of a transmitter
system that can be accessed by users must be tripped. If their response range is
adjustable, the ex‑factory setting must not be altered. If settings are changed inadvertently, the correct values specified in this documentation must be set.
2.3.2 Hazards from High‑Energy Electric Circuits
The instruments contain low-voltage circuits that can be fed from a voltage source with
an extremely low impedance (e.g. amplifier operating voltage). These circuits carry
dangerously high levels of energy. At Rohde & Schwarz, we treat these circuits in the
same way as circuits with hazardous contact voltages. Normally, these circuits are protected by covers to prevent unintentional contact. The cover has a warning label.
In practice it has been repeatedly shown that short circuits caused by small metallic
tools result in severe burns. For safety reasons, any high‑energy electric circuits in
areas of the equipment that can be accessed by users are concealed by protective
covers.
●
Exercise the same amount of caution for measurements on low‑impedance voltages (e.g. for repair purposes) that you would when performing measurements on
operating voltages which constitute a shock hazard.

2.3.3 Hazards from RF Radiation
2.3.3.1 Obligation to Instruct Personnel
Safety Instructions
Special Hazard Information
Wear suitable protective gear when necessary.
●
Before opening any equipment or removing a particular cover, turn of
supply and wait 5 minutes to ensure that capacitors have discharged sufficiently.
●
Do not discharge capacitors by short‑circuiting them.
●
The operator must train all personnel in the operation of this transmitter or instrument in line with EN60215 and/or IEC215. It is essential that these regular training
sessions emphasize the dangers related to high frequency that exist at the respective transmitter or instrument. Operating personnel are only authorized to adjust
and operate the equipment after they have completed the respective training sessions and their participation has been documented.
f the power
High‑energy RF circuits inside the transmitter or instrument are routed via conventional
removable RF connectors (e.g. type N). Depending on the output power, the output
ports of the transmitter and instrument are equipped with screw-type or plug-in RF
lines or ducts.
If RF lines or modules carry high power, the connection point or the entire module is
tagged with the general danger warning label (yellow triangle with a black exclamation
mark).
2.3.3.2 RF Shielding
Transmitters and instruments from Rohde & Schwarz are shielded so that even in the
immediate vicinity there is no danger from RF radiation when all RF lines are connected. This applies to statutory provisions in Germany, i.e. the regulation concerning electromagnetic fields:
Limits for electrical and magnetic field strengths of high‑frequency installations are
defined in the 26th ordinance of the German Federal Government's Emission Control
Act of December 16, 1996 (26. BImSchV).
2.3.3.3 Rules When Operating an Amplifier
Disconnecting RF lines that are in operation can result in arcs. These can cause burns
and eye injuries.
●
Operation of the amplifier is only permitted if a main or dummy antenna is connected
●
Never disconnect RF lines when the amplifier is in operation
●
Never open the amplifier or modules when the amplifier is in operation
●
Never operate the amplifier if RF lines are exposed
