2. 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 death.
Electrical Safety
If the information on electrical safety is not observed either at all 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 power supply matches the nominal voltage of the AC supply network.
2. If the product does not have a power switch for disconnection from the AC supply
network, the plug of the connecting cable is regarded as the disconnecting device.
In such cases, always ensure that the power plug is easily reachable and
accessible at all times (corresponding to the length of connecting cable, approx.
2 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, a disconnecting device must be provided at the system level.
3. 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. By taking
appropriate safety measures and carefully laying the power cable, you can ensure
that the cable will not be damaged and that no one can be hurt by, for example,
tripping over the cable or suffering an electric shock.
4. The product may be operated only from TN/TT supply networks fused with max.
16 A (higher fuse only after consulting with the Rohde & Schwarz group of
companies).
5. Do not insert the plug into sockets that are dusty or dirty. Insert the plug firmly and
all the way into the socket. Otherwise, sparks that result in fire and/or injuries may
occur.
6. Do not overload any sockets, extension cords or connector strips; doing so can
cause fire or electric shocks.
7. For measurements in circuits with voltages V
rms
> 30 V, suitable measures (e.g.
appropriate measuring equipment, fusing, current limiting, electrical separation,
insulation) should be taken to avoid any hazards.
8. Ensure that the connections with information technology equipment, e.g. PCs or
other industrial computers, comply with the IEC60950-1/EN60950-1 or IEC61010-
1/EN 61010-1 standards that apply in each case.
9. 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.
10. 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.
