1 Safety and regulatory information
The product documentation helps you use the product safely and efficiently. Follow the
instructions provided here and in the following chapters.
Intended use
The product is intended for the development, production and verification of electronic
components and devices in industrial, administrative, and laboratory environments.
Use the product only for its designated purpose. Observe the operating conditions and
performance limits stated in the data sheet.
Where do I find safety information?
Safety information is part of the product documentation. It warns you of potential dan-
gers and gives instructions on how to prevent personal injury or damage caused by
dangerous situations. Safety information is provided as follows:
●In Chapter 1.1, "Safety instructions", on page 15. The same information is provi-
ded in many languages as printed "Safety Instructions". The printed "Safety
Instructions" are delivered with the product.
●Throughout the documentation, safety instructions are provided when you need to
take care during setup or operation.
1.1 Safety instructions
Products from the Rohde & Schwarz group of companies are manufactured according
to the highest technical standards. To use the products safely, follow the instructions
provided here and in the product documentation. Keep the product documentation
nearby and offer it to other users.
Use the product only for its intended use and within its performance limits. Intended
use and limits are described in the product documentation such as the data sheet,
manuals and the printed "Safety Instructions". If you are unsure about the appropriate
use, contact Rohde & Schwarz customer service.
Using the product requires specialists or specially trained personnel. These users also
need sound knowledge of at least one of the languages in which the user interfaces
and the product documentation are available.
Never open the casing of the product. Only service personnel authorized by
Rohde & Schwarz are allowed to repair the product. If any part of the product is dam-
aged or broken, stop using the product. Contact Rohde & Schwarz customer service at
http://www.customersupport.rohde-schwarz.com.
Lifting and carrying the product
The product is heavy. Do not move or carry the product by yourself. A single person
can only carry a maximum of 18 kg safely depending on age, gender and physical con-
dition. Look up the maximum weight in the data sheet. Use the product handles to
Safety instructions

Safety and regulatory information
R&S®ZNA
16User Manual 1178.6462.02 ─ 29
move or carry the product. Do not lift by the accessories mounted on the product.
Accessories are not designed to carry the weight of the product.
To move the product safely, you can use lifting or transporting equipment such as lift
trucks and forklifts. Follow the instructions provided by the equipment manufacturer.
Choosing the operating site
Only use the product indoors. The product casing is not waterproof. Water that enters
can electrically connect the casing with live parts, which can lead to electric shock,
serious personal injury or death if you touch the casing. If Rohde & Schwarz provides
accessories designed for your product, e.g. a carrying bag, you can use the product
outdoors.
Unless otherwise specified, you can operate the product up to an altitude of 2000 m
above sea level. The product is suitable for pollution degree 2 environments where
nonconductive contamination can occur. For more information on environmental condi-
tions such as ambient temperature and humidity, see the data sheet.
Setting up the product
Always place the product on a stable, flat and level surface with the bottom of the prod-
uct facing down. If the product is designed for different positions, secure the product so
that it cannot fall over.
If the product has foldable feet, always fold the feet completely in or out to ensure sta-
bility. The feet can collapse if they are not folded out completely or if the product is
moved without lifting it. The foldable feet are designed to carry the weight of the prod-
uct, but not an extra load.
If stacking is possible, keep in mind that a stack of products can fall over and cause
injury.
If you mount products in a rack, ensure that the rack has sufficient load capacity and
stability. Observe the specifications of the rack manufacturer. Always install the prod-
ucts from the bottom shelf to the top shelf so that the rack stands securely. Secure the
product so that it cannot fall off the rack.
Connecting to power
The product is an overvoltage category II product. Connect the product to a fixed
installation used to supply energy-consuming equipment such as household applian-
ces and similar loads. Keep in mind that electrically powered products have risks, such
as electric shock, fire, personal injury or even death. Replace parts that are relevant to
safety only by original parts, e.g. power cables or fuses.
Take the following measures for your safety:
●Before switching on the product, ensure that the voltage and frequency indicated
on the product match the available power source. If the power adapter does not
adjust automatically, set the correct value and check the rating of the fuse.
●Only use the power cable delivered with the product. It complies with country-spe-
cific safety requirements. Only insert the plug into an outlet with protective conduc-
tor terminal.
Safety instructions

Safety and regulatory information
R&S®ZNA
17User Manual 1178.6462.02 ─ 29
●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.
●If you connect the product to an external power supply, use the one delivered with
the product or recommended in the product documentation. The external power
supply must conform to the country-specific regulations.
●Only connect the product to a power source with a fuse protection of maximum
20 A.
●Ensure that you can disconnect the product from the power source at any time.
Pull the power plug to disconnect the product. The power plug must be easily
accessible. If the product is integrated into a system that does not meet these
requirements, provide an easily accessible circuit breaker at the system level.
Cleaning the product
Use a dry, lint-free cloth to clean the product. When cleaning, keep in mind that the
casing is not waterproof. Do not use liquid cleaning agents.
Meaning of safety labels
Safety labels on the product warn against potential hazards.
Potential hazard
Read the product documentation to avoid personal injury or product damage.
Heavy product
Be careful when lifting, moving or carrying the product. Carrying the product requires a suffi-
cient number of persons or transport equipment.
Electrical hazard
Indicates live parts. Risk of electric shock, fire, personal injury or even death.
Hot surface
Do not touch. Risk of skin burns. Risk of fire.
Protective conductor terminal
Connect this terminal to a grounded external conductor or to protective ground. This connec-
tion protects you against electric shock if an electric problem occurs.
1.2 Warning messages in the documentation
A warning message points out a risk or danger that you need to be aware of. The sig-
nal word indicates the severity of the safety hazard and how likely it will occur if you do
not follow the safety precautions.
WARNING
Potentially hazardous situation. Could result in death or serious injury if not avoided.
