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.
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 Vrms > 30 V, suitable measures
(e.g. appropriate 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.
