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 by
personnel familiar with the potential risks of measuring electrical quantities.
Use the product only for its designated purpose. Observe the operating conditions and
performance limits stated in the data sheet.
Target audience
Only connect, set up and use a power supply if you are an electrically skilled person.
Electrically skilled persons have the relevant education and experience to enable them
to perceive risks and to avoid hazards that electricity can cause.
This document targets at all users, including installers, operators, technicians, mainte-
nance and service personnel.
Follow the safety instructions provided in Chapter 1.1, "Safety instructions",
on page 9 and the additional information provided during setup or operation proce-
dures.
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 9. 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.

10User Manual 5601.8919.02 ─ 08
Only people skilled in electrical work should connect, set up and use the product. Such
persons have the education and experience needed to recognize risks and avoid haz-
ards of working with electricity. These users also need sound knowledge of at least one
of the languages in which the user interfaces and the product documentation are avail-
able.
Reconfigure or adjust the product only as described in the product documentation or
the data sheet. Any other modifications can affect safety and are not permitted.
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
https://www.rohde-schwarz.com/support.
Lifting and carrying the product
Look up the maximum weight in the data sheet. A single person can only carry a maxi-
mum of 18 kg safely depending on age, gender and physical condition. If your product
is heavier than 18 kg, do not move or carry it by yourself.
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 to live parts, which can lead to electric shock, seri-
ous personal injury or death if you touch the casing.
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.
